CTCSS tone Detect
1. Set CH7/CODE1and SG to –122dBm with 67Hz tone
frequency, 400Hz deviation.
2. Check the Pin31 of IC105 to have square-wave, and low
for RF modulation off.
3. Repeat item 1 and 2 for code38(250.3Hz).
4. Repeat item 1 and 3 for CH14.
14.
Quiet tone det
1.Set unit to quiet noise mode.
2.Set CH1/CODE 1and SG to –60dBm with 67Hz tone
frequency, 400Hz deviation and 55Hz audio frequency,
400Hz deviation..
4. 55Hz tone frequency appear on TP 117.
15.
Normal Batter level
Detect
1. Provide 1.5V DC at BP102.
2. Battery level : 4.18+/-0.15V level 1, 3.8+ /-0.15V level 2,
level 3: 2.88+ /-0.15V.
3. Disconnect 1.5V DC at BP102.
4. Battery level : 3.85+/-0.15V level 1, 3.4+/-0.15V level 2,
level 3: 2.88+ /-0.15V.
16.
SCAN
1. Set SG RF level to –50dBm with 500Hz deviation,
100Hz modulation.
2. Press "Mon" key.
3. Unit shows channels 9 and code 13.
