For more details on registering frequencies to the memory channel, see the operating
manual.
zMake sure to use the corresponding numbers for the lower and upper limit memory channels.
zSet the PMS memory channel for performing the Programmable Memory scanning (PMS) as
follows.
•The scan width of the upper and lower limit frequencies must be 100 kHz or more.
•The lower and upper limit memory channels must be within the same frequency band.

Dual Receive (DW) Function
The transceiver is equipped with the following 3 types of Dual Receive Functions:
⿠VFO Dual Receive
⿠Memory Channel Dual Receive
⿠Home Channel Dual Receive
The transceiver checks for signals on the frequency registered to the selected memory
channel (Priority Memory Channel) once approximately every 5 seconds. When receiv-
ing a signal on the frequency registered to a priority memory channel, the Dual Receive
function temporarily pauses, and allows reception of the signals.
Example: Checking the priority memory channel “1” (145.000 MHz), while receiving
“432.500 MHz”.
VFO Priority
Memory Channel
The transceiver monitors signals
on the frequency registered to the
Priority Memory Channel, once
approximately every 5 seconds.
When the transceiver
receives a signal on the
frequency registered to the
priority memory channel,
dual reception stops and
signal receiver switches to
priority memory channel.
The transceiver returns to the
previous frequency quickly and
continues to receive mode when
there is no signal.

ARTS (Automatic Range Transponder System)
The ARTS feature uses DCS signaling to inform both parties when another ARTS
equipped station is within communications range. This may be particularly useful during
Search and Rescue situations, where it is important to stay in contact with the other
members of the group.
The stations must set up their DCS codes to the same code number, and then activate
their ARTS feature using the command appropriate for their transceiver. Alert ringers
may be activated, if desired.
Whenever the PTT switch is pressed, or every 15 or 25 seconds after ARTS is activated,
the transceiver will transmit a signal which includes a (subaudible) DCS code for about
one second. If another ARTS enabled transceiver is in range, the beeper will sound and
the display will show “IN.RNG”. When the other transceiver is out of range, “OUT.RNG”
is shown when the ARTS function is in operation.
Whether or not the PTT switch is pressed, the transceiver
may be programmed to transmit a CW ID, every 10 min-
utes.
If you move out of range for more than one minute (four pollings), the transceiver will
sense that no signal has been received, three beeps will sound, and the display will re-
vert to “OUT.RNG” If you move back into range, the transceiver will again beep, and the
display will change back to the “IN.RNG” indication.
During ARTS operation, it is not possible to change the operating frequency or other set-
tings. In order to resume normal operation, ARTS must be terminated. This is a safety
feature designed to prevent accidental loss of contact due to channel change, etc.
Basic ARTS Setup and Operation
1. Set all the transceivers to the same DCS code number, per the instructions on page
6.
2. Press and hold the [2] key.
• ARTS polling will starts.
• “OUT.RNG” will be displayed on the LCD.
3. Every 25 seconds, the transceiver will transmit a “polling” call to the other station.
• When that station responds with its own ARTS polling
signal, the display will change to “IN.RNG” to confirm
that the other station’s polling code response was re-
ceived.

19
4. Press the Function key (or press and hold the [2] key) to exit ARTS operation and
resume normal transceiver operation.
ARTS Polling Time Options
