DV Fast Data

Fast Data 

(Default: OFF)

Selects whether or not to use the DV Fast Data 

function for data communication in the DV mode.

The DV Fast Data function uses the data and the 

audio frames to send data approximately 3.5 times 

faster than the normal speed. So, no audio can be 

sent.

 •

OFF:  Sends data at a slow speed (approximately 

950 bps).

 • ON:   Sends data at a fast speed (approximately 

3480 bps).

 

L

Even if “ON” is selected, when you push the microphone’s 

[PTT], the data is sent at the slow speed, because the 

audio frame is used for the audio transmission. 

The GPS data speed is set in “GPS Data Speed.”

GPS Data Speed 

(Default: Slow)

Sets the GPS data speed when the data is sent using 

the DV Fast Data function.

 • Slow:  Sends GPS data in the slow speed 

(approximately 950 bps).

 •

Fast:  Sends GPS data in the fast speed 

(approximately 3480 bps).

TX Delay (PTT) 

(Default: 2sec)

Sets the time for when the transceiver returns to 

receive after sending DV data in the DV Fast Data 

mode using the microphone’s [PTT].

 •

OFF: 

 After releasing [PTT], the transceiver 

returns to receive.

 • 1 ~ 10sec:  After releasing [PTT], the transceiver 

sends data using the DV Fast Data 

mode for this set period. 

When the TX data is completely sent 

within this set period, the transceiver 

automatically returns to receive.

NOTE:

 This function is usable only when “DV Data 

TX” is set to “PTT.”

DV/DD Set

Standby Beep 

 

(Default: ON (to me:Alarm/High Tone)

Turns the Standby Beep function ON or OFF.

This function sounds a beep after a received signal 

disappears, in the DV mode.

 •

OFF:  Does not sound a beep after a received signal 

disappears.

 • ON:   Sounds a beep after a received signal 

disappears.

 • ON (to me:High Tone): 

       Sounds a high pitched beep when a received 

signal that is addressed to your call sign (MY) 

disappears. When any other received signal 

disappears, a regular beep sounds.

 • ON (to me:Alarm/High Tone): 

       Sounds alarm (PiRoPiRoPiRo) when a 

received signal that is addressed to your 

call sign (MY) disappears. When any other 

received signal disappears, a regular beep 

sounds.

 

L

The standby beep sounds even when “Beep 

(Confirmation)” is set to “OFF.”

 

L

The standby beep output level depends on the “Beep 

level” setting.

Auto Reply 

(Default: OFF)

Sets the Automatic Reply function to ON, OFF, or 

Voice. This function automatically replies to a call 

addressed to your own call sign (MY), even if you are 

away from the transceiver.

 •

OFF:  Turns OFF the function.

 • ON:   Replies with your own call sign (MY). (No 

audio reply is sent)

 • Voice:  Replies with your call sign (MY) and any 

Auto Reply message recorded on the SD 

card (up to 10 seconds). If no SD card is 

inserted, or no message is recorded, only 

your call sign is transmitted. The transmitted 

audio can be monitored.

 

L

When “ON” or “Voice” is selected, the Automatic Reply 

function is automatically turned OFF when you push the 

microphone’s [PTT].

DV Data TX 

(Default: Auto)

Selects whether to manually or automatically transmit 

data in the DV mode.

 • PTT:  Push the microphone’s [PTT] to manually 

transmit data.

 • Auto:  When data is input from a PC through the 

[USB] port, the transceiver automatically 

transmits it.
