The preamps amplify received signals in the receiver
front end to improve the signal-to-noise ratio and
sensitivity. A preamp is used when receiving weak
signals.

NOTE When you use the preamp while receiving
strong signals, the receiving signal may be distorted.
In such case, turn OFF the preamp.
Attenuator
The Attenuator prevents a desired signal from
becoming distorted when a very strong signal is near

RIT frequency
(3 digits)
RIT function
The RIT (Receive Increment Tuning) function
compensates for differences in frequencies of other
stations.
The function shifts the receive frequency up to .
without shifting the transmit frequency.
1. Push
RIT
.
• The RIT function turns ON.
LWhile using the Fine Tuning function (p. 3-3), the RIT
frequency is displayed in 4 digits, instead of 3.
LPushing
RIT
again turns OFF the RIT function.
2. Set the RIT frequency to match the receiving
station’s frequency.
LYou can reset the RIT frequency to “0.00” by holding
down
CLEAR
for 1 second.
LYou can add the frequency shift to the operating
frequency by holding down
RIT
for 1 second.
3. After communicating, push
