ing memory channel scanning.
Selected memory channel: You can specify selected memory channels so that only the
specific memory channels are scanned during memory scan-
ning.
1 Switch to the Memory mode, and then recall the memory
channel you want to specify as a skip memory channel or a
selected memory channel.
2 Press and hold M over 1 second.
Enters the Set mode.

Programmable Memory Channel Scan (PMS)
Registering to a Programmable Memory Channel
50 sets of PMS memory channels (L1/U1 to L50/U50) are available.
Specify the lower limit frequency of the frequency range you want to scan for memory
channel [L], and the upper limit frequency for [U].
Enter a number between 1 and 50 for . Use the same number for the lower and upper
limit memory channels.
Specify the lower limit frequency and upper limit frequency for the PMS memory channel
(See page 43).
PMS memory channels are located next to the last memory channel.
Pressing M scans PMS memory channels quickly in steps of 100 memory channels.
Example: When registering the lower limit frequency 145.160 MHz and the upper limit
frequency 145.460 MHz to a PMS memory channel.
Lower limit frequency L1 Upper limit frequency U1
Caution
When the upper and lower limit frequencies have been set in different step, be sure to set 100 kHz or
more in between.

Performing Programmable Memory Channel Scan
The programmable memory channel scan allows you to scan a specified frequency range
within the same frequency band.
1 Switch to the Memory mode.
Recall a PMS memory channel to which the lower limit fre-
quency or upper limit frequency is registered.
2 Press F and then 2.
Programmable memory channel scanning starts.
Tips • Turn O clockwise: Scanning is performed toward higher fre-
quencies.
Turn O counterclockwise: Scanning is performed toward
lower frequencies.
• When a signal is received during scanning, scanning stops for
5 seconds and this frequency is received.

Using the Digital GM Function
Using the Digital GM Function
(Digital Group Monitor Function)
What is the GM function?
The Digital GM (Group Monitor) Function automatically checks if there is another trans-
ceiver operating on the same frequency with the GM function within transmission range,
and displays the direction, distance and other information for each detected callsign on
the LCD. This convenient function not only lets you know if a friend is within transmission
range, but also enables instant confirmation of position information between group mem-
bers. Furthermore, by using this function, you can send messages and images between
group members.
Caution
The GM function does not function in the analog mode. Using the % key, switch the communication
mode to AMS (Auto Mode Select Function) or digital mode.
Tip
When transmitting image data while GM function is active, the transmission mode automatically switches
to FR mode (High Speed Data Communication Mode).The transmission mode will automatically return
to the previous V/D mode (Voice/Data Simultaneous Communication Mode).
Standard Operation of the GM Function
Using the GM Function
There are 2 ways of using the Digital GM Function.
(1) Show all stations (up to 24 stations) operating with the GM function.
(2) Register IDs of friends in a group and use it only between registered members.
Displaying all stations (up to 24 stations) operating with the GM function.
1 Adjust frequency to A band.
2 Press D to open the group list.
3 Turn O to select [ALL].
4 Press H.
The ID, distance, and direction of all stations (up to 24) with-
in communication range operating with the GM function on
the same frequency are displayed.
If there are more than 3 stations, turn O to scroll through
the display.
When the GM function is active, not only can you verify if a station is in or out of com-
munication range but the position (direction and distance) information as well.

Using the APRS Function
Using the APRS Function
What is the APRS (Automatic Packet Reporting System)?
Although there are several functions that display position information using GPS in ama-
teur radios, the APRS is data communication system that transmits data such as position
information and messages using a format proposed by Bob Bruninga of WB4APR.
Upon receiving an APRS signal from the remote station, information such as direction and
distance to the remote station from your station and speed of the remote station appear
on the LCD of your transceiver.

Example of display when APRS signal is received
The settings (initial settings) such as callsign and symbol for your station must be applied
before using the APRS function.
For details, refer to the APRS function instruction manual (please download it from our
company website).

Using the GPS Function
Using the GPS Function
What is GPS?
GPS (Global Positioning System) is a space-based satellite navigation system that pro-
vides location and time information anywhere on the earth. It was developed by the U.S.
Department of Defense as a military system. It receives signals from three or more of
about 30 GPS satellites flying at an altitude of about 20,000 km, and displays the current
position (latitude, longitude, and altitude) within a tolerance of several meters. In addition,
GPS can receive the exact time from the satellite’s onboard atomic clock.
Activating the GPS Function
To activate the GPS function, select [9 APROS] → [23GPS POWER], and then select
[GPS ON] in the Set mode.
Tips
• Default: ON
When the GPS function on the transceiver is turned ON, internal clock settings and posi-
tion settings for your station are automatically obtained from the GPS data.
1 Press and hold M for over 1 second to enter the Set mode.
2 Turn O to select [9 APRS].
3 Press H.
4 Turn O to select [20 GPS POWER].
5 Press H.
6 Turn O to select [GPS ON].
7 Press p to set the GPS Function to ON, and exit the Set
mode.
Tips
• Tip Information about the current positions of radio stations provided by GPS can be registered to
10 memory channels (P1 to P10). Registered position information can be used to set the position of
your station.
• When the GPS function is active, the power consumption increases by about 40 mA. As a result, the
battery life is reduced by about 20% compared to when the GPS function is deactivated.
• To use the GPS function during APRS operation, be sure to select [9 APRS] → [24MY POSITION],
and then select [GPS] in the Set mode.

Method of Positioning by GPS
Displaying Current Position Information of Your Station
1 Turn on the transceiver.
2 Press and hold M for over 1 second to enter the Set mode.
3 Turn O to select [1 DISPLAY].
4 Press H.
5 Turn O to select [1 GPS POWER].
6 Press H.
7 GPS data appears on the LCD.
An arrow icon (the direction in which you are heading), your
current position, number of satellites, longitude, latitude,
and altitude appear on the LCD.
Tips • The arrow icon (the direction in which you are heading) will not
appear and the latitude/altitude blinks until GPS satellite data is acquired.
• When GPS satellite data has been acquired, the arrow icon (the direction in which you are
heading) will appear, the latitude/altitude will change from blinking to lit, and your current posi-
tion will be displayed.
• If acquisition of GPS satellite data is interrupted due to an obstacle, such as a building or tun-
nel, only the arrow icon (the direction in which you are heading) disappears.
8 Press O to scroll the screen, and display the current time.
Pressing O again displays GPS data.
The GPS screens will transition each time H is pressed.
9. Press p.
The screen returns from the GPS screen to the normal fre-
quency display. (Not return to the transmission state)
Displaying Position Information of Remote Station in Digital Mode
With the V/D mode C4FM digital, because GPS position information is transmitted si-
multaneously with voice signals, the direction and position of the remote station can be
displayed in real-time even while communicating.
For details, see “Real-Time Navigation Function” on page 73.
Tip
• Even if the GPS function of your station is set to OFF, position information of the remote station can
be displayed in V/D mode.
Caution
If the GPS function is not active, the remote station will not be able to acquire position information for
your station.
