4-5 Test Procedure
1. AMPS(FM)
TEST ITEMS PROCEDURE
1. PREPARATION Set test equipments up.
Confirm that the phone is in the Analog Mode!
( “10000” or “10001” at Test Command “2 0”.)
“* 7 5 9 # 8 1 3 5 8 0” : Enter the Test Mode
“0 1” : Suspend
“4 6” : Initialize Vocoder in Analog mode
If a wrong key would be selected, press “#”, and then enter new command.
To exit the Test Mode at any time, just press [0 2].
2. RF “0 1” : Suspend.
POWER “4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“1 0 2” : RF Power level selection, “2” means one of the power levels (0~7).
Measurement of the Power Output Levels
Level RF Power
0 ~ 2 + 27 dBm + 0.3/-4 dB
3 + 23 dBm + 2/-4 dB
4 + 19 dBm + 2/-4dB
5 + 15 dBm + 2/-4dB
6 + 12 dBm + 2/-4dB
7 + 9 dBm + 2/-4dB
“0 8” : Carrier off
Note 1 : In case of using the antenna cable, compensation for th cable loss should be added
(about 1.5dB).
Note 2 : To prevent phones from being damaged, they must be measured only by calibrated test
equipments.
Warning !
Adjustments without calibrated equipments can cause phones to be heated excessively and
would void the warranty.
3. TX “0 1” : Suspend.
FREQUENCY “4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
Measure the TX frequency : 835.89 MHz ± 2.5ppm.
4. VOICE “0 1” : Suspend.
DEVIATION “4 6” : Initialize Vocoder in Analog mode.
“0 9 0 3 6 3 #” : Set channel to 363.
“0 7” : Carrier On.
“1 4” : TX Audio unmute.
Set the audio generator output to 1kHz, 3.0Vrms.
Measure the Tx voice deviation by using the HPF of 20Hz and the LPF of 99kHz
(spec : less than ±12kHz).
