Compenser™Functional Description
Functional Description
The COMPENSER™ is a bi-directional transmitting and receiving booster which
compensates for all cable and plug losses which occur in the signal path
between the mobile phone and the external antenna. This provides optimum
call quality through optimized transmitting and receiving characteristics.
The COMPENSER™ is ready for operation when the vehicle's ignition is turned
on. When there is no telephone call in progress, only the two receiving
amplifiers are active. During a telephone call the two transmitting amplifiers are
also active. The COMPENSER™ continues to be operational for approx. 2 hours
after turning off the ignition. Only after the end of this time the COMPENSER™
switches off completely (standby); this allows continued use during short stops.
In the standby mode the power consumption is minimal (< 0.1 mA), thereby
sparing the car battery. When the ignition is turned on again, the
COMPENSER™ is active again.
The timer function can be put out of operation by wiring the ignition connection
to the permanent plus (fig. 3, terminal 30, +). The COMPENSER™ is always on
then (CAUTION! This means constant power consumption and use of the car
battery!)
