RF Tuning Instructions
General
All tuning operations of the TME-1 are carried out using the WinTesla ser vice software.WinTesla interfaces with TME-1 via the FLA-26 service adapter.
For tuning the TME-1, use the same setup as for flashing the unit.
The tuning values of the phone are stored on the non-volatile memory of the RPM-3
GSM transceiver.. The contents of this memory can be read by the service software and
saved as a file. The program also enables writing the default tuning pa rameters, in which
case all tuning steps should be carried out.
During tuning, proceed as follows:
• Take care not to damage sensitive measuring instruments with exces sive RF
power. A spectrum analyzer may require an attenuator. TME-1 maximum output power may exceed 33 dBm (2 W) in GSM 900 band and 30 dBm (1 W) in
GSM1800 band.
• 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!
Required Equipment
• PC/AT computer with WinTesla service software; see separate section for
instructions on installation and use.
• Service accessories; see equipment setup lists.
• GSM radio telephone test station or separate measuring equipment as follows:
- RF generator
- pulse power meter
- spectrum analyzer
- attenuator
Equipment Setup
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 PKD1 between the PC and your printer cable.
Next see the following lists for correct equipment.

• 4. Pull out the TME-1 antenna
• 5. Connect the XRP-3 RF cable in the TME-1antenna socket for measurments.
NOTE! DO NOT IN ANY CIRCUMSTANCE CONNECT THE PCS-1 CABLE IN THE TME-1
SOCKET!
Tuning Steps
RX Calibration (AGC + AFC) for both bands
Reference values for the received signal strength meter are program tuned.
RSSI reference signal level programming:
• Select Product -> Band -> GSM
• Select Tuning -> RX Calibration
• Connect RF generator to TME-1 antenna conn at 947.067710 MHz.
• Adjust signal generator level to -55 dBm + cable attenuation.
• Press OK button
• Adjust signal generator level to -80 dBm + cable attenuation.
• Press OK button.
