To search for a repeater’s sub-audible tone frequency,
a tone scan is available.
By monitoring a repeater signal with a tone squelch or
DTCS, you can determine the tone frequency neces-
sary to open the repeater or the squelch.
Select the desired frequency band. (p. 35) q

code and its polarity is displayed. You can select the de-
sired polarity by pushing [POL](D).
“NN”: Normal polarity for both transmit and receive.
“NR”: Normal polarity for transmit and reverse polarity for
receive.
“RN”: Reverse polarity for transmit and normal polarity for
receive.
“RR”: Reverse polarity for both transmit and receive.

• “Repeater Tone SCAN,” “TSQL Tone SCAN” or “DTCS

decreases.
• If
“Up/Down” is selected as

or DTCS code is set.

setting.
Touch [SCAN]( i D) to cancel the scan.
When the tone scan or DTCS code scan is used in
the Memory or Call channel mode, the detected tone
frequency or code can be temporarily used.
To save the detected tone frequency or code setting,
you must overwrite the Memory or Call channel data.
