Teaching Control Unit For Garage Door Opener
WARNING:
Danger of accident if persons, animals or objects lie in the swinging range of the controlled mechanism during operation of the garage door opener.
- Ensure there are no persons, animals or objects in the swinging range of the controlled mechanism during operation of the garage door opener.
- Observe the safety instructions for the original hand-held transmitter.
To operate the particular device (e.g. garage door, gate to property, alarm system):
- Press the appropriate key on keypad "A". LED "B" lights up during signal transmission.
Operating instructions:
- Always use the garage door opener in the direction of travel. Otherwise range limitations cannot be ruled out.
- Before selling the vehicle, erase the programmed garage door opener signals on keypad "A".
- To determine whether the original hand-held transmitter is equipped with a fixed or variable code, please read the instructions for the original hand-held transmitter.
- In the case of a standard fixed code, the LED in the roof console is permanently lit during the transmission process. No further steps are necessary for the operation of compatible systems.
- If the system set is not activated by the garage door opener control unit, this may be because the original hand-held transmitter is equipped with a variable code.
Assigning Garage Door Opener Signals To Keys
Garage door opener with fixed code system
Observe the operating instructions for the original hand-held transmitter (e.g. of the garage door opener).
1. Press the two outer keys "A" I and III in the roof console. Do not release these again keys until the LED "B" begins to flash after approx. 20 seconds.
NOTE: This operation erases the standard codes set in the factory. Do not repeat this operation if additional hand-held transmitters are to be taught.
2. Hold the original hand-held transmitter for the unit that is to be taught at a constant distance of 5 - 20 cm from the roof console and observe the LED in the roof console "B".
NOTE: The distance required between the hand-held transmitter and the garage door opener control unit depends on the system used. A number of attempts may be necessary. Each setting tried must be maintained for at least 15 seconds before trying out another position.
3. Simultaneously press the key on the hand-held transmitter and the desired key on the roof console I, II or III. Hold keys depressed until step 4 has been completed.
4. The LED in the roof console first flashes slowly and then rapidly. As soon as the LED flashes rapidly, release both keys. The rapidly flashing LED "B" confirms that the new frequency signal has been successfully programmed.
5. To assign garage door opener signals to further keys, repeat steps 2 to 3.
Garage door opener with variable code system
Using the following steps, it can be checked whether the garage door drive (or other system) is equipped with a variable code.
- Check operating instructions for the garage door drive (or other system) for specification of a variable code.
- The hand-held transmitter appears to program the garage door opener control unit but fails to actuate the garage door (or other system).
- Press the programmed key "A" in the roof console and hold. In the case of a variable code system, the LED "B" flashes rapidly for a short time and then remains constantly on for two seconds. This pattern is repeated for up to 20 seconds.
If the garage door opener control unit has been programmed to a variable code system, it will still have to be synchronized with this system on completion of programming before it will work correctly.
Variable code synchronization
The vehicle must be in range of the radio remote controlled garage door drive (or other system).
1. Locate the setup button at the top part of the motor on the garage door drive. The exact position and colour can vary depending on the manufacturer of the garage door opener (operating instructions of the garage door drive - Teaching additional hand-held transmitter).
2. Press the Setup button at the top part of the motor on the garage door drive (this then normally activates a Setup LED display).
NOTE: After step 2, it takes on average 30 seconds to initiate step 3.
3. Press and release the programmed key "A" in the roof console. Press the same key a second time and release again to complete the setup procedure (for some garage door openers it may be necessary to repeat this procedure a third time to complete the adjustment).
4. To assign garage door opener signals to further keys, repeat steps 1 to 3.
Re-programming individual keys for the garage door opener control unit
If another radio remote controlled system is to be programmed to an already assigned transmitter channel, perform the following steps. The existing programming of the particular transmitter channel will be lost.
1. Keep the desired key "A" I, II, or III depressed until step 4 has been performed.
2. If the LED "B" starts to flash slowly (after 20 seconds), hold the hand-held transmitter at a distance of 5 - 20 cm in front of the keys "A" in the roof console.
NOTE: Observe the LED and maintain the required distance between the hand-held transmitter and garage door opener control unit for at least 15 seconds. A number of attempts may be necessary as different hand-held transmitters require different distances.
3. Press the programmed key A in the roof console and hold.
4. The LED "B" in the roof console first flashes slowly and then rapidly. As soon as the LED begins to flash more rapidly, release both keys.
Erasing programmed keys for the garage door opener control unit
The keys can only be re-programmed individually but cannot be erased individually. To erase the existing programming of all three transmitter channels, proceed as follows:
1. Press the two outer keys I and III in the roof console and hold for 20 seconds until the indicator lamp begins to flash.
2. Release the keys.
The integrated garage door opener control unit is now in setup mode (learning mode) and can be re-programmed at any time.
NOTE: As a precautionary measure, it is advisable to erase the programming of the garage door opener control unit before selling the vehicle.
Coding country coding
NOTE: The Euro Home Link (RoW variant) must be coded for various countries because of diverse national frequency registrations and modulations.
Press keys I and III on the Home Link to set regional codes (country codes for Europe) and keep them pressed for approx. 30 seconds until the LED goes out (the LED flashes after 20 seconds and goes out after another 10 seconds).
1. Release the keys.
2. Press keys I and III on the Home Link again and press key II briefly after approx. 1 second.
One flash Rest of Europe (e.g. Germany)
Two flashes France
Three flashes U.K.
Four flashes Italy
3. The number of flashes indicates the country code (continue to hold down the outer keys I and III).
4. The country code can now be incremented by pressing the II key. Each time you press the II key, another country is set. After 4 flashes, it returns to one flash, e.g. for Germany.
5. Release all keys once you have set the country coding.
6. Press keys I and III for approx. 20 seconds to get into Training mode (the LED flashes slowly after about 20 seconds).
7. Original hand-held transmitters can now be taught. Refer to 'Assigning garage door opener signals
