RF Front-end Tuning
1. Connect the DC voltmeter to
TP5001
(BAND A)
and
TP5002
(BAND B) on the RX-MAIN unit,
then inject a 439.050 MHz signal at a level of +10
dBμV (with 1kHz modulation ± 3.5 kHz devia-
tion) from the RF signal generator.
2.
Set the RX-MAIN-UNIT frequency to 439.050
MHz.
3.
Press t
he [
P1
]
key of the
Microphone to set the
alignment menu Item to "
Adj 01 TUN/A
".
4. Adjust the
DIAL
knob for maximum deflection
on the DC Voltmeter and then turn the dialin
the opposite direction until the meter deflection
drops slightly lower than maximum.
5. Set the RX-MAIN-UNIT and RF signal genera-
tor frequency to 145.050 MHz.
6. Adjust the
DIAL
knob for maximum deflection
on the DC Voltmeter and then turn the dialin
the opposite direction until the meter deflection
drops slightly lower than maximum.
7.
Set the RF signal generator frequency to
439.050MHz.
8.
Set the RX-MAIN-UNIT frequency to 439.050
MHz of the Band B.
9.
Press t
he [
P2
]
key of the
Microphone to set the
alignment menu Item to "
Adj 01 TUN/B
".
10. Adjust the
DIAL
knob for maximum deflection
