4 FUNCTION OPERATIONS
W Dualwatch operation
Dualwatch monitors 2 same mode frequencies simul-
taneously.
During dualwatch, both frequencies should be on the
same band because the bandpass filter in the RF
circuit is selected for the MAIN readout frequency.
@ Seta desired frequency.
®© Push [DUALWATCH] for 2 sec.
- Equalized receive frequency and " (DUALWATCH)" ap-
pear in the SUB readout. This quick dualwatch func-
tion can be turned OFF. (p. 46)
- Pushing [DUALWATCH] momentarily activates the
dualwatch with the previously operated frequency.

(3) Set another desired frequency using the sub dial
or SUB [F-INP].
@ Adjust [BALANCE] to set a suitable signal
strength balance between the MAIN and SUB
readout frequencies. |
- S-meter shows the combined signal strength.
©) To transmit on the SUB readout frequency, push
[CHANGE] or [SPLIT].
RIT function can be used for the MAIN readout
readout (MAIN readout when the split function is
Z OFF; SUB readout when the split function is ON).

W Monitor function
The monitor function allows you to monitor your
transmit IF signals in any mode through the speaker.
Use for checking the voice characteristics when
[MIC TONE] is adjusted or the transmit low-pass/
high-pass filters* are in use. The CW sidetone
functions when [MONITOR] is OFF in CW mode.
* For equipped type.
@ Push [MONITOR] IN.
CG) Adjust [MONI GAIN] while transmitting if desired.

e Scanning during dualwatch
Scanning operates only for the MAIN readout. To
operate the scan during dualwatch, scan on the MAIN
readout and use the SUB readout for your QSO using
both dualwatch and split frequency operation.
OU Program the desired programmed scan edges in
the same amateur band. See p. 52 for program-
ming.
@ Push [SPLIT] to turn the split frequency function
ON.

-The MAIN and SUB readout frequencies are
equalized and the dualwatch function is turned ON.
© Push [SCAN] to start the programmed scan.
- Scan activates on the MAIN readout between the
programmed scan edges.
- Transmitting on the SUB readout stops the scan.
