The signal of the infrared transmitter keys or of the infrared spare keys can be rendered visible using an infrared indicator card (e.g. IR-A2, available from the electronics trade, e.g. Conrad Elektronik).

The indicator card must first of all be charged in daylight. After this, hold the indicator card in a darkened room directly in front of the transmission line of the infrared transmitter key and press the transmit button. If the infrared transmitter key transmits a signal, This is recognizable from the green dot-shaped illuminated area in the indicator field.

Whether a signal transmitted by the infrared key reaches the infrared control module can also be checked as stated in the diagnosis information (test step IR signal control cable).

It is not possible to determine whether the signal transmitted is correctly coded (lock system number).
