WRR-805A (CE, AU)
Switch and Control Setting
MONITOR control (RV361) : Minimum position
MUTING switch (S605) :
OFF
Channel setting : Setting of the channel is to be perform
with the MODE switch (S601) , SET
switch (S604) , “
+
” switch (S602) and
“
_
” switch (S603).
CE62 model :
Group 00, 6301 channel (806.125 MHz)
CE69 model :
Group 00, 6933 channel (858.125 MHz)
AU66 model :
Group 00, 6701 channel (799.250 MHz)
Procedure
(1) Connect the audio analyzer to the OUTPUT connector
via MIC amp.
(2) Connect the signal generator to the ANTENNA
connector.
(3) Set the signal generator as follows :
FREQUENCY(Carrier frequency)
CE62 model : 806.125 MHz
CE69 model : 858.125 MHz
AU66 model : 799.250 MHz
RF OUTPUT (Output level) : 60 dB
u
V
EMF
(=
_
53 dBm)
MODULATION (Modulation frequency) : 1 kHz
DEVIATION (Frequency deviation) :
±
5 kHz
(4) Read the output level of the OUTPUT connector (Audio
analyzer indication level).
This level is specified to be 0 dB.
(5) Turn OFF the MODULATION of the signal generator
(No modulation).
(6) Check that output level of the OUTPUT is
_
61 dB or
less (S/N is 61 dB or more with A-weighted filter) as
compared with the level of procedure (4) above.
(7) Change the RF OUTPUT (output level) of the signal
generator as shown below.
RF OUTPUT (output level) : 10 dB
u
V
EMF
(=
_
103 dBm)
(8) Check that output level of the TUNER OUTPUT is
_
38
dB or less (S/N is 38 dB or more with A-weighted filter)
as compared with the level of procedure (4) above.
(9) Change the RF OUTPUT (output level) of the signal
generator as shown below.
RF OUTPUT (output level) : 60 dB
u
V
EMF
(=
_
53 dBm)
(10)Set the audio analyzer to the distortion mode.
(11)Turn ON the MODULATION of the signal generator.
(12)Check that distortion ratio is 0.9 % or less (
_
41 dB or
less) with A-weighted filter.
(13)Set the channel and FREQUENCY (carrier frequency)
of the signal generator as shown
1
and
2
below.
Perform the procedures (1) to (12) above, for each
channel setting (
1
and
2
).
