(6) RF Level Indicator Check
Procedure
n
The checking procedures describe that the URX-M2 (to be
adjusted) is installed into the Tuner [1] slot on the MB-X6 or
MB-806.
1. Set the URX-M2 and MB-X6/MB-806 as follows :
. URX-M2 Front panel (Tuner [1])
Channel setting :
U30 model ; Group 03, 32-01 channel (578.125 MHz)
U42 model ; Group 03, 44-01 channel (650.125 MHz)
CE62 model ; Group 04, 63-32 channel (810.000 MHz)
CE67 model ; Group 04, 68-32 channel (850.000 MHz)
KR model ; Group 12, 60-01 channel (746.125 MHz)
Muting : ON (Normal mode)
. MB-X6/MB-806 Rear panel
ATT (ANTENNA A, B) switch : 0 dB
2. Connect the signal generator to the ANTENNA A IN
connector with DC cut fixture.
3. Set the signal generator as follows :

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) : 0 dBuVEMF (= _113 dBm)
MODULATION (Modulation frequency) : 1 kHz
DEVIATION (Frequency deviation)
4. Increase gradually the output level from the signal gen-
erator, and check that the output level of the signal gen-
erator is as follows when the RF input level indicator
(Tuner [1]) lights.

5. Connect the signal generator to the ANTENNA B IN
connector with DC cut fixture.
6. Perform the procedures 3 to 4 above.
7. Set the channel setting (Tuner [1]) and FREQUENCY
(carrier frequency) of the signal generator as shown 1
and 2 below.
