(6) Set the channel setting and FREQUENCY (carrier
frequency) of the signal generator as shown 1 and 2
below.
Perform the procedures (2) through (5) above, for each
channel setting (1 and 2).
1 Channel setting:
U64 model: Group 00, 6401 channel (770.125 MHz)
U66 model: Group 00, 6601 channel (782.125 MHz)
U68 model: Group 00, 6801 channel (794.125 MHz)
Signal generator setting:
FREQUENCY(Carrier frequency)
U64 model : 770.125 MHz
U66 model : 782.125 MHz
U68 model : 794.125 MHz
2 Channel setting:
U64 model : Group 00, 6547 channel (781.875 MHz)
U66 model : Group 00, 6747 channel (793.875 MHz)
U68 model : Group 00, 6947 channel (805.875 MHz)
Signal generator setting:
FREQUENCY (Carrier frequency)
U64 model: 781.875 MHz
U66 model: 793.875 MHz

6. AF level indicator/AF indicator check
Procedure
(1) Set the WRR-802A as follows;
Channel setting:
U64 model; Group 00, 6501 channel (776.125 MHz)
U66 model; Group 00, 6701 channel (788.125 MHz)
U68 model; Group 00, 6901 channel (800.125 MHz)
VOL. control: Any position
Muting: OFF
(2) Connect the signal generator to the ANTENNA A IN
connector.
(3) Set the signal generator as follows:
Signal generator setting
FREQUENCY(carrier frequency)
U64 model; 776.125 MHz
U66 model; 788.125 MHz
U68 model; 800.125 MHz
RF OUTPUT (Output level): 60 dBuV
MODULATION (Modulation frequency): 1 kHz
(4) Increase gradually DEVIATION (frequency deviation)
of the signal generator starting from ± 3 kHz, and
check that the deviation of the signal generator is
± (5.0 ± 1.0) kHz with the AF indicator as follows.
