The transmitter and the battery are housed in the housing of the remote con-
trol. The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few
hundred metres. Obstacles between the radio remote control and the vehicle,
bad weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating on or off, hold the remote control vertically,
with the aerial
A
» Fig. 128 pointing upwards. The antenna must not be cov-
ered with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio re-
mote control, if the distance between the radio remote control and the vehicle
is at least 2 m.
After pressing the button, the warning light in the remote control gives the
user different kinds of feedback.
