Noise- Detector
1. Set SG to –120dBm with 1.5KHz deviation., 1KHz AF
on CH7.
2. Press ”Mon” key and Adjust VR502 for transient state @
10dB SINAD.
3. Check high state @8 to 15dB SINAD.
15.
CTCSS Tone Detect
1. Set CH15/CODE1 and SG to –60dBm with 67Hz tone
frequency, 400Hz deviation.
2. Check the Pin22 of IC101 to have square-wave, and low
for RF modulation off.
3. Repeat item 1 and 2 for code38 (250.3Hz).
4. Repeat item 1 ~ 3 for CH14.
16.
CDCSS Tone Detect
1. Set CH15/CODE99 and SG to –60dBm with 503 Octal
Code tone frequency, 400Hz deviation.
2. Check the Pin22 of IC101 to have square-wave, and low
for RF modulation off.
3. Repeat item 1 and 2 for code39 (023 Octal Code).
4. Repeat item 1 ~ 3 for CH14.
17.
Quiet Noise Detect
1. Set unit to quiet noise mode
2. Set CH15/CODE1and SG to –60dBm with 67Hz tone
frequency, 400Hz deviation and 55 Hz audio frequency,
1K deviation..
3. 55 Hz tone frequency appear on
TP117
.
18.
Normal Batter level
Detect
1. If the battery voltage level less than 4.3V, the battery
icon display as
.
2. If the battery voltage level more than 5.2V, the battery
icon display as
.

Weather Alert Detect
1. Set unit to Weather Alert mode
2. Set SG RF level to –60dBm with 3KHz deviation at
1050Hz audio frequency.
3. Check auto open WX mode of two way mode.
20. SCAN
4. Set SG RF level to –50dBm with 500Hz deviation,
100Hz modulation.
5. Press "Mon" key.
6. Unit shows channels 9 and code 13.
