Introduction

The HFL system works only with Acura approved Bluetooth(R)-enabled cell phones with a hands-free profile. If you are not sure if your cell phone is compatible with the HFL system, Acura has a dedicated call center and web site www.acura.com/handsfreelink, to answer your questions.

The HFL system allows you to make and receive hands-free calls. It cannot control the phone's performance (call quality and signal strength). For more information about performance and performance problems, refer to Dropped Calls.

Most HFL complaints are due to pairing, configuration, or compatibility issues. Contact the Acura call center before replacing the HandsFreeLink control unit.

Checking Cell Phone Compatibility

The most important step in troubleshooting HFL issues is to identify the client's phone model, the software version, and the callular carrier that experiences the HFL problem. Not all phones with the Bluetooth feature and a hands-free profile are compatible with the Acura HFL system.

Go to www.acura.com/handsfreelink or call Acura's dedicated call center, and check if the client's phone is approved to work with the Acura HFL system.

NOTE:

- These approved, archived, and currently testing phone model lists are constantly changing, so make sure you view them frequently.

- Phones are added as they are approved.

- Phones can be removed from the approved list if a software bug is discovered that makes the phone incompatible. There phones can be added back to the approved list if the phone manufacturer corrects the bug.

- If the software bug is corrected, a new software version is created and may be listed in the Supported Features section of the phone.

- The Acura web site now includes the software versions that are tested and approved. When software versions are listed, you need to know which version is loaded on the phone to help you troubleshoot the client's complaint. If you cannot access the Acura web site, call the HFL call center for further assistance. The call center is open Monday thru Friday from 6:00 a.m. to 6:00 p.m. CST; Saturday from 7:00 a.m. to 6:00 p.m. CST; and Sunday from 8:00 a.m. to 6:00 p.m. CST.

Voice Control Tips and Improving Voice Recognition

To give a voice command to the HFL system, press and release the HFL TALK button. Always wait for the beep, then give your command in a clear, natural voice. The HFL microphone is on the ceiling by the map lights.

'09 model: If the HFL system doesn't recognize your voice command, you'll hear "Pardon." If your command isn't recognized a second time, you'll hear "Please repeat." If your command isn't recognized a third time, the HFL system sends you to its Help menu.

'10 model: If the HFL system doesn't recognize your voice command, you'll hear "Pardon? Press the TALK button and say a command. For a list of commands, say handsfreehelp." If your command isn't recognized a second time, you'll hear "Bluetooth handsfreelink main menu. Available calling options are call, dial, redial, and transfer. Available setup options are phone setup, phone book, and system setup. For more detailed help, say handsfreehelp." If your command isn't recognized a third time, the HFL system sends you to its Help menu.

To hear a list of available options at any time, press the HFL TALK button and say "Hands-free help."

The HFL system may have problems recognizing some voices. To improve voice recognition:

- Close the windows and the moonroof.

- Set the fan speed to low (1 or 2) or off.

- Adjust the airflow from the center vents down, so that it's not blowing against the microphone on the ceiling.

- Speak in a clear and natural voice. If the system cannot recognize your command, try speaking louder, in a deeper tone.

- If the background noise is too loud, you may need to speak louder.

- If you speak with something in your mouth, or your voice is too high, the system may not interpret your command correctly.

- Find out if the problem is with one person or with everyone who uses the system. If the system has a problem with only one person's voice, this is a system limitation.

Many issues result from the client not using the system properly. Make sure the client is using the HFL buttons and not the navigation TALK/navigation BACK buttons. When the HFL TALK button is pressed, the client hears one audible tone. When the HFL BACK button is pressed, the client hears two audible tones. Make sure to press the HFL BACK button to exit the HFL main menu after completing a call and before giving any navigation commands.

The HFL system may experience a number recognition issue, such as when a client says a set of numbers in a group unrecognized by the system. The HFL system understands phone numbers in specific blocks of 1, 3, 4, 7, and 10 numbers. For example, the system understands:





The system may become confused if numbers are stated in other blocks, as the following:





Navigation Through Menus

To skip a voice prompt, press and release the HFL TALK button while the HFL system is speaking. The system beings listening for your next voice command.

To go back a step in a voice command sequence, press and release the HFL BACK button, or press the HFL TALK button and say "Go back." If you don't say anything while the HFL system is listening for your voice command, it times out and stops voice recognition. The next time you press and release the HFL TALK button, the HFL system begins listening from the point it timed out.

If you've finished or want to stop a voice command sequence at any time, press and release the HFL BACK button, or press and release the HFL TALK button, wait for the beep, and say "Cancel." The next time you press and release the HFL TALK button, the HFL system begins from its main menu. To avoid keeping the audio system muted, press and release the HFL BACK button when you are finished.

NOTE: You can say multiple commands in one sequence, like "Phone setup-pair" after pressing the HFL TALK button.

Pairing a Cell Phone ('09 model)

You must pair an approved Bluetooth-compatible phone to the HFL system before you can make and receive calls. For a current list of approved phones and specific phone pairing instructions for each phone, see Checking Cell Phone Compatibility, go to www.acura.com/handsfreelink.

The following procedure works for most phones. If you cannot pair a phone to the HFL system with this procedure, refer to the phone's operating manual, visit www.acura.com/handsfreelink.

NOTE:

- You cannot pair a phone while the vehicle is moving.

- Your phone must be in Discovery Mode.

- A maximum of six Bluetooth-compatible phones can be paired to the system.

1. With the phone on and the ignition switch in ACCESSORY (I) or ON (II), press and release the HFL TALK button. After the beep, say "Phone setup." The HFL responds, "Phone setup options are status, pair, edit, delete, and list."

2. Press and release the HFL TALK button. After the beep, say "Pair." The HFL responds, "The pairing process requires operation of your mobile phone. For safety, only perform this function while the vehicle is stopped. State a four-digit code for pairing. Note this code. It will be requested by the phone."

3. Press and release the HFL TALK button. After the beep, say the four-digit code you want to use. This can be any four-digit number you want. For example, say "1, 2, 3, 4." The HFL responds, "1, 2, 3, 4. Is this correct?"

4. Press and release the HFL TALK button. After the beep, say "Yes." The HFL responds, "HFL is now searching for a Bluetooth phone. Make sure the phone you are trying to pair is in Discovery mode." If these steps do not work on the phone you are pairing, refer to the phone's operating manual.

5. Follow the prompts on your phone to get it into its Discovery mode. The phone will search for the HFL. When it comes up, select HandsFreeLink from the list of options displayed on your phone.

6. When asked by the phone, enter the four-digit code from step 3 into your phone. The HFL responds, "A new phone has been found. What would you like to name this phone?"

7. Press and release the HFL TALK button. After the beep, say the name you want to use. For example, say "Tom's phone." The HFL responds, "Tom's phone has been successfully paired. Returning to the main menu."

Pairing a Cell Phone ('10 model)

You must pair an approved Bluetooth-compatible phone to the HFL system before you can make and receive calls. For a current list of approved phones and specific phone pairing instructions for each phone, see Checking Cell Phone Compatibility, go to www.acura.com/handsfreelink.

The following procedure works for most phones. If you cannot pair a phone to the HFL system with this procedure, refer to the phone's operating manual, visit www.acura.com/handsfreelink.

NOTE:

- You cannot pair a phone while the vehicle is moving.

- A maximum of six Bluetooth-compatible phones can be paired to the system.

1. With the phone on and the ignition switch in ACCESSORY (I) or ON (II), press and release the HFL TALK button. After the beep, say "Phone setup." The HFL responds, "Phone setup options are pair, edit, delete, list, status, next phone, set pairing code."

2. Press and release the HFL TALK button. After the beep, say "Pair." The HFL responds, "The pairing process requires operation of your mobile phone. For safety, only perform this function while the vehicle is stopped. For proper system function a compatible Bluetooth phone is required. Please visit www.acura.com/handsfreelink for a list of approved phones and other system information. Handsfreelink is waiting to pair with a Bluetooth phone. From your phone, search for Bluetooth devices, and select handsfreelink. When prompted by your mobile phone enter the pairing code 0000."

3. When prompted by your mobile phone, enter the pairing code 0000. Refer to your cell phone user guide for more information about searching for a Bluetooth device.

4. Once the phone is recognized by the HFL system, it responds, "HandsFreeLink has connected to a new phone. A name is needed to identify this phone. Press the talk button and say a name. For example, John's phone. "

5. Press and release the HFL TALK button. After the beep, say the name you want to use. For example, say "Tom's phone." The HFL responds, "Tom's phone has been successfully paired. Returning to the main menu."

Pairing Troubleshooting

Many pairing issues are resolved by altering the client's phone settings.

Bluetooth feature settings must be turned on. Phone manufacturers set the default to disable Bluetooth features to conserve battery life. Cell phones may provide procedures to Temporary Power On Bluetooth, or Power On Bluetooth. Turn the Bluetooth feature on, pair the phone to the vehicle, and confirm the phone is linked. Do this by turning the phone off and back on. Make or receive a call to confirm that the cell phone is successfully paired.

When the phone's Bluetooth feature is on, other handsfree accessories such as earpieces or headsets may automatically reconnect to the phone when you turn on the accessory or move it within range of the cell phone. This results in the phone not connecting to the HFL system when the client enters the vehicle. You must unlink the hands-free accessory from the phone before the HFL system can reconnect.

Some phones have an Auto Answer setting that functions with a headset. This setting must be turned off or the HFL system cannot accept any incoming calls. When this setting is on, it blocks the HFL system from answering the call, and the call goes to voice mail. This can cause the client to think that the cell phone is not paired properly.

If the HFL system has six phones paired, it will not tell you that it has reached its maximum, and will not allow you to pair a new phone. To check how many phones are paired, press and release the HFL TALK button. After the beep, say "Phone setup list." The HFL system lists every assigned phone name paired with it, then finishes by saying "The entire list has been read. Returning to the main menu." Count the number of phones listed. If there are six, you must delete one phone before adding a new one.

Pairing Checks

For more information about pairing, refer to the cell phone owner's manual, or go to www.acura.com/handsfreelink.

1. Is the cell phone compatible with the HFL?

2. Is the Bluetooth feature turned on?

3. Is the client using the HFL buttons, not the navigation TALK/navigation BACK buttons, when pairing?

4. Is the cell phone battery fully charged, and is there good signal strength when pairing?

5. Do a soft reset on the cell phone.

6. If the client is trying to pair a Blackberry(R) or Palm TreoTM device, make sure the client uses the shift key when entering the pass code. If the shift key is not pressed, the client may be entering letters. The HFL does not recognize letters.
