Tuning Instructions
General
The tuning operations of the TFF-3 are carried out using the Service Soft-
ware. The Service Software program turns the phone into Locals Mode,
in which the phone can be outwardly controlled via the M2BUS interface.
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 XCM-3 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 13.5 V .
Equipment Setup
Turn off the computer before connecting the cable to avoid possible damage to the serial port.

Connect the modular cable between the terminal and the modular adapter. The modular adapter must be connected to the D9–D25 cable. Connect the 9–pin male D–connector in your PC serial port.
For transmit, audio measuring and adjustment connect ADS–1 EAR/MIC
breakout cables as follows:
– EAR line to test equipment AF INPUT
– MIC line to test equipment AF GEN OUTPUT
Connect PCS-1 power cable to the power supply. Supply voltage is set to
13.5 V.

Manual Tuning Steps
General
If any repairs or replacements have not been made, manual tuning is not
necessary on the phone. Spare modules have been tuned at the factory.
If some repair or replacements have been made, manual tuning is nessessary.
If you do not want to use phone country version dependent tuning channels, proceed as follows:
1. Choose RF controls from the Configure menu.
2. Change channel values.
3. Choose Write File –button in order to save channel values in
”TESLA.ini” –file.
TFF-3
Tuning Instructions
The program saves the channel settings and uses them every time when
Tunings or Testing menu is chosen. The program uses ordinary channels
depending on the phone country version, if you don’t change channels.
