Introduction

Thank you for choosing an COMPENSER UMTS/GSM-MMC from Funkwerk
Dabendorf!
The COMPENSER ensures optimum transmitting and receiving power in your
vehicle and therefore enhances the operation of your GSM and UMTS end
devices.

Functional description

The COMPENSER UMTS/GSM MMC contains bidirectional transmitting and
receiving amplifiers for the respective frequency ranges of GSM 900, GSM 1800
and UMTS Band I. All cable and connector losses that arise on the signal's path
from the mobile phone to the external antenna are compensated for. Even
mobile phone cradles with an antenna connection are included here. Optimum
call quality is therefore achieved, as the transmitting and receiving properties
are optimised.
The COMPENSER is ready for operation as the vehicle's ignition is switched on.
If no telephone call is in progress, only the receiving amplifiers will be active.
When a telephone call is in progress, the corresponding transmitting amplifier
is also active.
The device remains ready for operation for approx. 2 hours after the ignition is
switched off. The COMPENSER does not switch off completely until this time has
elapsed (standby); this means it can continue to be used when journeys are
briefly interrupted. Current consumption in standby mode is minimal (< 0.1 mA),
thereby avoiding load on the car battery. The COMPENSER is reactivated when
the ignition is switched back on.
The timer function can be disabled by wiring the ignition connection (Ign.) to con-
stant positive (Fig. 3, terminal 30, +). This means that the COMPENSER is always
switched on. (CAUTION! Please note that a constant current consumption of
approx. 250 mA occurs in the process and a load is placed on the car battery!)
