Individual Test Options

A list describing the use of the test program options follows below. A summary of the test options and possible parameter values is given as well.

1 CH NUMBER

2 TX POWER

4 FLASHER

Setting of channel number Choose any chanel in the ETACS system (0-600, 1329-2047). Default setting is channel 1. To change channel number; enter a 4-digit decimal number followed by #. Use * and # to step backwards/forwards. Channel number and signal strength are displayed.

power level 2; maximum output power When the power reduction function is activated in menu 76, power level 2 will be displayed as ‘S’. When the extra power option in menu 76 is activated, power level 2 will be displayed as ‘X’.

Used only when loading the program into a terminal.

5 PWR CAL

6 TX DETECT

Calibration of power levels. Transmitter is turned on and tuned to the calibration channel. Modify the power levels with the following keys:

# / *

mitter test and a transmitter leakage test. To start the test, press any key except The result is displayed when the test is finished:

leakage test failed Factory and level 5 repair only

Test/Service Programs

9 RF CAL

10 RX SENS

Calibrates the RSSI levels based on the level of the signal cur-

rently being received.

The value determined for each level is the minimum strength

signal for that level, averaged over 16 readings to provide a

more reliable value.

The value for level 0 is used to update the Receiver Carrier

Detect (RXCD) such that signals below this level are ignored.

This value (plus a fixed offset) also determines the minimum

signal threshold for the AFC.

When the received signal is below this threshold, the AFC pro-

vides TCXO compensation based on a default temperature com-

pensation table.

The values for level 1 and 5 are used to determine the RSSI

graph to display.

The values for level 2, 3 and 4 are interpolated from these two

reference levels.
