Important safety notes G
WARNING
When you operate or program the garage door with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

Problems when programming
If you have problems when programming the

garage door drive remote control Aand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control Afor the garage door drive.
R Replace the batteries in garage door drive
remote control A. This increases the likeli-
hood that garage door drive remote control
A will transmit a strong and precise signal to
the integrated garage door opener.
R When programming, hold remote control A
at varying distances and angles from but-
tons ;to? that you are programming. Try
various angles at a distance between 5and
20 cm or at the same angle but at varying
distances.
R If another remote control Ais available for
the same garage door drive, perform the pro-
gramming steps again using this remote con- trol A. Before performing these steps, make
sure that new batteries have been fitted in
garage door drive remote control A.R
Note that some remote controls transmit only
for a limited period (the indicator lamp on theremote control goes out). Press button Bon
remote control Aagain before transmission
ends.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
