DV Set items (Continued)
Fast Data
DV Set > DV Fast Data > Fast Data
Select 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 the slow speed (approximately
950 bps).
• ON: Sends data at the fast speed (approximately
3480 bps).
L Even if "ON" is selected, while holding down [PTT],
the data is sent at the slow speed, because the
audio frame is used for the microphone audio
transmission and the audio transmission has
priority.
The GPS data speed is set in "GPS Data Speed."
GPS Data Speed
DV Set > DV Fast Data > GPS Data Speed
Set the GPS data speed when the data is sent using
the DV Fast Data function.
L When you send the GPS data to other transceivers
that can receive only slow speed data, set to
"Slow."
• 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)
DV Set > DV Fast Data > TX Delay (PTT)
Set the TX delay time.
In the data communication mode and after releasing
[PTT], the transceiver automatically sends the data
using the DV Fast Data function for this set period.
• OFF: After releasing [PTT], the transceiver
returns to receive.
• 1 ~ 10sec: After releasing [PTT], the transceiver
sends data by using the DV Fast Data
function for this set period.
The transceiver automatically returns to
receive when the TX data is completely
sent, or when this set period ends,
whichever is sooner.
NOTE: This function is usable only when "DV Data
TX" is set to "PTT."
(Default: OFF) Digital Monitor
DV Set > Digital Monitor
Select a receive mode when [MONI] is pushed in the
DV mode.

Digital Repeater Set
DV Set > Digital Repeater Set
Turn the Digital Repeater Setting function ON or OFF.
In any DV mode except when using the DR function,
and when accessing a repeater that has a call sign
that is different than the transceiver's setting, this
function reads the repeater's signal and automatically
sets the repeater call sign in R1 and R2.
• OFF: Turns OFF the function.
• ON:
(Default: Slow)
DV Auto Detect
DV Set > DV Auto Detect
Turn the DV mode automatic detect function ON or
OFF. If you receive an FM signal in the DV mode, this
function temporarily switches to the FM mode.
• OFF: Turns OFF the function. The operating mode

RX Record (RPT)
(Default: 2sec)
DV Set > RX Record (RPT)
The transceiver can record the data of up to 50
individual calls. When the received signal includes a
status message ("UR?" or "RPT?") that is sent back
from the access repeater, you can record up to 50
messages, or only the last call, in the Received Call
Record.
• ALL:
• Latest Only: Records only the last call.
