FAULT FINDING

Warning!
Neither the Power button, nor the rear panel Power switch, isolates the input supply from the
equipment. Lethal voltages are still present in the base station's internal power supply. To
ensure safe working during maintenance, the ac and dc input supplies must be
disconnected from the base station.
The T6M base station contains the following replaceable modules (see Figures 6, 7, and 8):
A T6M radio module (a self-contained transceiver).
q
An interface module that interconnects the various external signals, and the power supplies, to
q
the radio module.
A switched mode power supply (SMPS).
q
The base station's modules are manufactured using surface mount technology. Because of this, and the
specialist test equipment required to set up the circuits, spares are limited to modules and components
as listed on page 47.
The following table gives help in fault diagnosis.
