Technical Documentation
Some vehicles have a main switch (e.g. gas trucks), which separates the
vehicles chassis from the negative lead of the battery. Do under no cir-
cumstances pass this switch, i.e. the grounding of the reducer must be
taken from the body of the vehicle, NOT directly from the battery.
WARNING : DO NOT INSTALL REDUCER
– To engine compartment
– Where there isn't adequate amount of air for cooling (under the
carpet, etc.)
– Where there is risk of moisture (condensed water, etc.)
Car Radio Muting (XCRM)
The phone offers a feature that can mute the car radio automatically dur-
ing a conversation. This feature is convenient and provides for safer
handsfree operation. The car radio muting feature based on grounded
line, so it means that in standby, the yellow wire (XCRM) is not grounded
and car radio works normally, but during a call, line is grounded and car
radio is muted. The maximum load that this line can handle is 100 mA.
Note: an auxiliary relay or muting unit must be used when the car radio doesn't have a
mute feature available.
