(5) RF Squelch Level/RF Indicator Check
1. Set the URX-P2 as follows :
Channel setting :
U30 model ; Group 03, 3201 channel
U42 model ; Group 03, 4401 channel
CE62 model ; Group 04, 6332 channel
CE67 model ; Group 04, 6832 channel
KR model ; Group 12, 6001 channel (746.125 MHz)
RF squelch : ON (Normal mode)
Monitor level :MON.01 (minimum value)
2. Connect the signal generator to the CN201/RF-130
board with the MM-SMA conversion connector and the
RF adjusting cable.
3. Set the signal generator as follows :
Signal generator setting
FREQUENCY (carrier frequency) :
U30 model ; 578.125 MHz
U42 model ; 650.125 MHz
CE62 model ; 810.000 MHz
CE67 model ; 850.000 MHz
KR model ; 746.125 MHz
RF OUTPUT (Output level) : 60 dBuV
MODULATION (Modulation frequency) : 1 kHz

4. Check that RF Indicator LED lights (green) and "NO
TONE" message appears on LCD (URX-P2).
5. Change the RF OUTPUT (output level) of the signal
generator as shown below.
RF OUTPUT (output level) : 5 dBuV
6. Check that RF Indicator LED goes off (green) and "NO
TONE" message disappears on LCD (URX-P2).
7. Increase gradually the RF OUTPUT (output level) of
the signal generator. Check that RF OUTPUT (output
± 5 dB at when RF Indicator lights
level) is 15 dBuV
