Tuning Instructions

General

The tuning operations of the THF-13 are carried out using the Service

Software. The Service Software program turns the phone into Locals

Mode, in which the phone can be outwardly controlled via the M2BUS in-

terface.

Tuning is based on the Service Software communicating with the D/A and

A/D converters of the phone.

The calibration data of the phone resides on the EEPROM. The contents

of the EEPROM can be read by the Service Software. The program also

enables writing of the factory preset calibration data to the EEPROM, af-

ter which the whole tuning process should be carried out again.

If a repair has been carried out on the RF section of a system module

then the appropriate tunings should be performed as described in the fol-

lowing section and using th on-screen help menus as a guide. Spare sys-

tem modules will be delivered pre-tuned from the factory and will not re-

quire retuning.

PAMS Technical Documentation

During tuning, proceed as follows:

– Take care not to damage sensitive measuring instruments with exces-

sive RF power.

– Carry out all tuning steps in the shortest possible time to avoid exces-

sive heating of RF units.
– Perform all tuning steps in the order presented.
– Never try to mask a fault by tuning it out!

Minimum Required Servicing Equipment

–PC/AT Computer with Service Software installed: See Service Software
instructions.

–M2BUS cable DAU–9P and other service software accessories; see
equipment set–up pictures.

–Audio analyzer.
–RF power meter, power measurement sensitivity –10 dBm.
–RF generator.
–Device to provide specified test modulation to modulate RF generator.
–Multimeter or DVM.
–Attenuator and branching unit.
–Power supply, nom. voltage 3.6 V (with service battery BBD–3 voltage

is 8.2 V).

Equipment Setup

Turn off the computer before connecting the cable to avoid possible dam­age to the serial port.
