Tuning Instructions
General
All tuning operations of the NSC–1/3 and NSW–1/3 phones are carried
out using the service software. The service software turns the phone into
the locals mode, in which the phone can be outwardly controlled via the
MBUS interface.
Tuning is based on the software communicating with the D/A and A/D
converters of the phone. In some instances the phone processor will also
calculate the required correction parameter.
The tuning values of the phone reside on the EEPROM. The contents of
the EEPROM can be read by the service software and saved as a file.
This is advisable when there is need to retain that information, e.g. in
view of replacement of the circuit. The program also enables writing the
default parameters on the EEPROM, in which case all tuning steps should
be carried out.
Technical Documentation
Note: NSC–1 and –3 do not have upper band componets. NSC–1 and –3
are only 800 Mhz tranceivers.
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!

Equipment Setup
Tuning Instructions
Caution: Make sure that you have switched off the PC and the printer
before making connections !
Caution: Do not connect the PKD–1 key to the serial port. You may
damage your PKD–1 !
Attach the protection key PKD–1 to parallel port one (25–pin female
D–connector) of the PC. When connecting the PKD–1 to the parallel port
be sure that you insert the PC end of the PKD–1 to the PC (male side). If
you use a printer on parallel port one, place the PKD–1 between the PC
and your printer cable.
Next connect the M2BUS service cable, DAU–9P, to the serial port
(RS–232) of the computer. Attach one end of the service cable to the PC
serial port and the other end to the service box, JBA–4. For servicing the
phone with the covers in place the service box should always be used.
When the phone covers are removed the jigs should be used.
For audio measurements connect the audio cable, ADS–1, as follows:
– EAR line to AF INPUT of test equipment
– MIC line to MOD GEN OUTPUT of test equipment

Tuning Steps
1. AFC Tuning (Analog)
This tuning adjusts reference oscillators frequency so that network’s frequency criterias will be met.
This adjustment loads the Analog center frequency DAC value into the
EEPROM. When doing this, a spectrum analyzer must be used.
Note: Do not leave tuning on. The analog transmitting takes maximium
current. The tunning can damage the phone or service battery. The service battery will be heated.
The Spectrum analyzer settings are shown in AFC tuning window.
–Set power supply voltage 8.4 V to service battery (or 3.6 V to jig).
– Connect the spectrum analyzer to antenna connector.
Technical Documentation
– Check that spectrum analyzer frequence is correct.
– Tune the center frequence 832.500 Mhz +/– 200 kHz.
– Once Center frequence (CFR) is correct, press
2. VCTCXO Tuning
This tuning is to check that the radio unit has correct adjustment to meet
networks criteria for frequency stability.
This adjustment loads the VCTCXO DAC value into the EEPROM. RF

5. TX Power... LOW BAND / HIGH BAND
NOTE: Use Service Battery connected to 1.5A 8.4V power supply or use
phone’s own battery.
This tuning is to adjust radio unit’s output power level values according to
system specification.
This adjustment loads the power levels of the phone transmitter into the
EEPROM. When doing this, a pulse power meter or spectrum analyzer
must be used.
The <Settings> shows spectrum analyzer settings.
