Test Program
How to Use
This document will describe the use of the built-in test program for the EF738.
After the more extensive descriptions found in Individual Test Options, an overview
follows in the form of a table with data referring to the different options.
This table will become a handy alternative after having some experience of the test
program.
Initiating the Test Program
The test program is initiated from the special test handset;
by holding down the M button and pressing 90 40 59 or
by pressing 90 40 59 followed by M M
However, if the Test Program Enter function is enabled in the telephone, the pro-
gram can be initiated and run directly from the keypad by pressing the same
sequence (M = MENU).
When the phone enters the test mode, the hardware becomes initialized and the text
TEST INPUT appears in the display.
To step forward and backwards in the test program; press SEND and RCL.
To choose a specific test; press its number followed by the # button.
Return to TEST INPUT
Press the C or M button to return to the input mode where the TEST INPUT prompt
is displayed.
Exit
To exit from the test program; select test option 99 and press the # button.

Test/Service Programs
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 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 fol-
lowed by #.
Use * and # to step backwards/forwards.
Channel number and signal strength are displayed.
2 TX POWER Sets the transmitter on and offF and determines the output power
level.
8 off
7 power level 7; minimum output power
6 power level 6
5 power level 5
4 power level 4
3 power level 3
2 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'.
4 FLASHER Used only when loading the program into a terminal.
5 PWR CAL Calibration of power levels.
Transmitter is turned on and tuned to the calibration channel.
Modify the power levels with the following keys:
# / * increases/decreases the power level
M+S stores the value and steps to next power level;
transmitter is turned on
M+# starts calibration and displays power level;
steps forward to next power level (2->3->...->7->2).
C turns off TX, restores channel no., returns to menu 0.
6 TX DETECT Performs two simple transmitter tests: a general Go/NoGo trans-
mitter test and a transmitter leakage test.
To start the test, press any key except C.
The result is displayed when the test is finished:
FF both tests passed
01 general transmitter test failed
02 leakage test failed
7 TX SENS Factory and level 5 repair only
8
Test/Service Programs
9 RF CAL 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.
M+# displays the next RSSI level number and its current value
M+S reads an averaged RSSI value and stores it

temp + age + (frozen) freq. error for up to 30 sec.)
5 locked using short count;
(RSSI good, use smoothed freqcompensation);
only entered when current savings is active;
short freq. measurements is used to find freq. error com-
pensation
