■Activating the Tone Function
1Confirm that FM mode has been selected on the VFO(s) {page 19}.
•When using 2 VFOs, you must select FM mode on both VFOs.
2Press [NB/T/ 7].
•“T” appears.
Note:
◆You can select a tone frequency independent of a CTCSS frequency.
◆When 1750 Hz is selected, the transceiver sends a 500 ms tone burst each time transmission starts. You cannot transmit 1750 Hz tone manually.
TONE FREQ. ID SCAN
Note: You cannot use the Tone function with the CTCSS
function.
■Selecting a Tone Frequency
1While “T” appears (Tone function is ON), press [NB/T/ 7] (1 s).
•The current tone frequency appears. The default is 88.5 Hz.
2Turn the MULTI control to select the desired tone frequency.
•The available tone frequencies are listed in the following table.
3Press [MTR/ CLR] to complete the setting.
This function scans through all tone frequencies to identify the incoming tone frequency on a received signal. You may find this useful when you do not know the tone frequency that the repeater uses.
1While the Tone function is ON (“T” is visible), press [NB/T/ 7] (1 s).
•The current tone frequency appears.
2Press [SCAN/ SG.SEL] to activate the Tone frequency ID scan.
•While the transceiver is receiving a signal, “T” blinks and every tone frequency is scanned. When the tone frequency is identified, the transceiver stops scanning and the identified frequency is displayed.
•Press [SCAN/ SG.SEL] to stop scanning while the tone frequency ID scan is active.
•Press [SCAN/ SG.SEL] again to resume scanning.
Note: Received signals are audible while scanning is in progress.
