Activating the Tone Function

 

 

 

 

 

 

 

 

Note:

 

 

 

 

 

 

 

1Confirm that FM mode has been selected on the VFO(s).

When using two VFOs, you must select FM mode on both VFOs.

2Press [4/ TONE/SEL] to switch the Tone function ON (or OFF).

“T” appears when the function is ON.

Note:

You cannot use the Tone function with the CTCSS or DCS functions.

You need to activate the Tone function only when selecting one of the 38 standard frequencies. The selection you make here will not affect the transmission of the 1750 Hz tone.

Selecting a Tone Frequency

1 Press [FUNC], [4/ TONE/SEL].

The current tone frequency appears. The default is 88.5 Hz.

2Turn the MULTI/ CH control to select the appropriate tone frequency.

The available tone frequencies are listed in the following table.

3Press [FUNC], [4/ TONE/SEL] to complete the setting.

Use Nos. 01 to 39 shown in the table above when selecting tone frequencies via Wireless Remote Control {page 82}.

You can select a tone frequency independent of a CTCSS frequency.

Selecting Continuous or Burst

Access Menu No. 42 to select “Continuous” or “Burst”. With Continuous selected, the transceiver sends the tone continuously during the transmission. With Burst selected, the transceiver sends a 500 ms tone each time transmission starts. When using the 144, 430/ 440 MHz, or 1.2 GHz band, continuous tones are always transmitted, regardless of the selection.

Transmitting a 1750 Hz Tone

Most repeaters in Europe require transceivers to transmit a 1750 Hz tone. With 1750 Hz tone selected, pressing [4/ TONE/SEL] causes the transceiver to transmit the 1750 Hz tone. Releasing the key ceases transmission of the code. Some repeaters in Europe must receive continuous signals for a certain period of time, following a 1750 Hz tone. This transceiver is capable of remaining in transmit mode for

2 seconds after transmitting the 1750 Hz tone. Access Menu No. 44 and select “ON”.
