INSTALLATION INSTALLATION
This chapter describes the installation procedure for integrating this radio into a typical
amateur radio station. It is presumed that you possess technical knowledge and conceptu-
al understanding consistent with your status as a licensed radio amateur. Please take some
extra time to make certain that the important safety and technical requirements detailed in
this chapter are followed closely.
INSTALLATION TIPS
To ensure long life of the components, be certain to provide adequate ventilation around
the cabinet of this transceiver. Do not install the transceiver on top of another heat-gen-
erating device (such as a power supply or amplier), and do not place equipment, books,
or papers on top of this transceiver.Avoid heating vents and window locations that could
expose the transceiver to excessive direct sunlight, especially in hot climates. This trans-
ceiver should not be used in an environment where the ambient temperature exceeds +140
°F (+60 °C).
SAFETY INFORMATION
This transceiver is an electrical apparatus, as well as a generator of RF (Radio Frequency)
energy, and you should exercise all safety precautions as are appropriate for this type of
device. These safety tips apply to any device installed in a well-designed amateur radio
station.
Never allow unsupervised children to play in the vicinity of your transceiver or an-
tenna installation.
Be certain to wrap any wire or cable splices thoroughly with insulating electrical
tape, to prevent short circuits.
Do not route cables or wires through door jambs or other locations where, through
wear and tear, they may become frayed and shorted to ground or to each other.
Do not stand in front of a directional antenna while you are transmitting into that
antenna.
Do not install a directional antenna in any location where humans or pets may be
walking in the main directional lobe of the antenna’s radiation pattern.
In mobile installations, it is preferable to mount your antenna on top of the roof of
the vehicle, if feasible, so as to utilize the car body as a counterpoise for the anten-
na and raise the radiation pattern as far away from passengers as possible.
During vehicular operation when stopped (in a parking lot, for example), make it a
practice to switch to Low power if there are people walking nearby.
Never wear dual-earmuff headphones while driving a vehicle.
Do not attempt to drive your vehicle while making a telephone call on an auto-
patch using the DTMF microphone. Pull over to the side of the road, whether dial-
ing manually or using the auto-dial feature.

INSTALLATION INSTALLATION
MOBILE INSTALLATION
This transceiver must only be installed in vehicles having a 13.8 Volt negative ground
electrical system. Mount the transceiver where the display, controls, and microphone are
easily accessible, using the supplied mounting bracket.
The transceiver may be installed in almost any location, but should not be positioned near
a heating vent nor anywhere where it might interfere with driving (either visually or me-
chanically). Make sure to provide plenty of space on all sides of the transceiver so that air
can ow freely around the radio’s case. Refer to the diagrams showing proper installation
procedures.
Mobile Power Connections
To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the supplied DC
power cable directly to the battery terminals. Do not attempt to defeat or bypass the DC
cable’s fuse - it is there to protect you, your transceiver, and your vehicle’s electrical
system.
Warining!
Never apply AC power to the power cable of the transceiver, nor DC voltage great-
erthan 15.8 Volts. When replacing the fuse, only use a 15-A fast-blow type. Failure
to observe these safety precautions will void the Limited Warranty on this product.
Before connecting the transceiver, check the voltage at the battery terminals while
revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regu-
lator before proceeding with installation.
Connect the RED power cable lead to the POSITIVE (+) battery terminal, and the
BLACK power cable lead to the NEGATIVE (–) terminal. If you need to extend the
power cable, use #12 AWG or larger insulated, stranded copper wire. Solder the splice
connections carefully, and wrap the connections thoroughly with insulating electrical
tape.
Before connecting the cable to the transceiver, verify the voltage and polarity of the
voltage at the transceiver end of the DC cable using a DC voltmeter. Now connect the
transceiver to the DC cable.

INSTALLATION INSTALLATION
BASE STATION INSTALLATION
The transceiver is ideal for base station use as well as in mobile installations. The trans-
ceiver is specically designed to integrate into your station easily, using the information
to follow as a reference.
AC Power Supplies
Operation of this transceiver from an AC line requires a power source capable of provid-
ing at least 10 Amps continuously at 13.8 Volts DC. The FP-1023 and FP-1030A AC
Power Supplies are available from your dealer to satisfy these requirements. Other well-
regulated power supplies may be used, as well, if they meet the above voltage and current
specications.
Use the DC power cable supplied with your transceiver for making power connections to
the power supply. Connect the RED power cable lead to the POSITIVE (+) power supply
terminal, and connect the BLACK power cable lead to the NEGATIVE (–) power supply
terminal.
Packet Radio Terminal Node Controller (TNC)
The transceiver provides a convenient rear-panel DATA jack for easy connections to your
TNC. This connector is a standard mini-DIN connector. A pre-wired connector and cable
assembly option, model CT-39A, is available from your local dealer.
The transceiver’s DATA jack connections are optimized for the data transmission and re-
ception speed in use. In accordance with industry standards, the signal levels, impedanc-
es, and bandwidths are signicantly different on 9600 bps as opposed to 1200 bps. If your
TNC does not provide multiple lines to accommodate such optimization, you may still be
able to utilize your TNC, if it is designed for multiple-radio use, by connecting the TNC
“Radio 1” port to the 1200 bps lines on the TRANSCEIVER, and the “Radio 2” port to
the 9600 bps lines.
The pin connections of the Data connector are shown below.

BASE STATION INSTALLATION
Note that 9600 bps packet transmit-deviation adjustment is very critical to successful opera-
tion, and can only be accomplished using a calibrated deviation meter (such as that found on
an FM Service Monitor used in a communications service center). In most cases, the Packet
Data Input level (set via a potentiometer inside the TNC) must be adjusted to provide a devi-
ation of ±2.75 kHz (±0.25 kHz). Check with your packet node’s sysop if you have any ques-
tions about the appropriate deviation level for your network. Note also that high throughput
on 9600 bps frequently requires strong signals, so you may wish to consider the use of a
directional antenna such as a Yagi for communication with high-speed packet nodes.
The setting of the 1200 bps Packet Data Input level is much less critical than it is at 9600 bps,
and satisfactory adjustment to the optimum (±2.5 ~ ±3.5 kHz) deviation can usually be done
“by ear” by adjusting the TNC’s 1200 bps TX Audio Level potentiometer so that the outgo-
ing packets (as monitored on a separate VHF or UHF receiver) are approximately the same
level as (A) the DTMF tones or (B) the 1750 Hz Burst tone produced using the microphone.
Finally, note that the Menu (“Set”) mode allows you to set the Packet data rate (1200 or
9600 bps) independently for each band. If you have trouble getting your TRANSCEIVER
to respond correctly during packet operation, check to be certain that you do not have
Menu #26 (P K T. S P D ) set to the wrong data rate.
You may activate the microphone input while operating on the packet mode via the Menu
#25 (P K T. M I C ), if desired. Generally, we do not recommend this, as a “live” micro-
phone’s audio input will tend to reduce throughput by interfering with the packets being
transmitted by your radio.

BASIC OPERATION BASIC OPERATION
TURNING THE TRANSCEIVER ON AND OFF
1. To turn the transceiver on, press and hold in the
PWR ( ) switch for 1/2 second.
When you turn on the transceiver, the current DC
supply voltage is indicated on the LCD for 2 sec-
onds. After this interval, the display will switch its
normal indication of the operating frequency.
2. To turn the transceiver off, again press and hold in
the PWR ( ) switch for 1/2 second.
ADJUSTING THE AUDIO VOLUME LEVEL AND SQUELCH SETTING
At first, set the SQL knob fully counter-clockwise.
Now, you may rotate the VOL knob clockwise to ad-
just the receiver volume for a comfortable listening
level, using the background noise as a reference.
To set the squelch, turn the SQL knob clockwise a
slightly past the point where the background noise is
muted. This is the point of best sensitivity to weak
signals, and we recommend that you not rotate the SQL knob very much past the point
where the background noise is just silenced.
A special “RF Squelch” feature is provided on this radio. This feature allows you to set
the squelch so that only signals exceeding a certain S-meter level will open the squelch.
SELECTING THE OPERATING BAND
Press the [BAND(SET)] key to move the operating
band:
144 MHz  250 MHz  350 MHz 
430 MHz  850 MHz  144 MHz ......
You may select the operating band by pressing
the microphone’s [P1] key.
FREQUENCY NAVAGATION
1) Tuning Dial
Rotating the DIAL knob allows tuning in the pre-programmed steps established for the
VFO frequency. Clockwise rotation of the DIAL knob causes the transceiver to be tuned
toward a higher frequency, while counter-clockwise
rotation will lower the operating frequency.
Press the [MHz(PRI)] key momentarily, then rotate
the DIAL knob, to change the frequency steps to 1
MHz per step. This feature is extremely useful for
making rapid frequency excursions over the wide tun-
ing range of the transceiver.
2) Direct Keypad Frequency Entry
The keypad of the MH-RM50 DTMF Microphone may be used for direct entry of the op-
erating frequency.
To enter a frequency from the MH-RM50 keypad, just press the numbered digits in the
proper sequence. There is no “Decimal point” key on the MH-RM50 keypad.
Examples: To enter 146.480 MHz, press [1]  [4]  [6]  [4]  [8]  [0]
To enter 433.000 MHz, press [4]  [3]  [3]  [0]  [0]  [0]
3) Scanning
From the VFO mode, press and hold in the [SCAN(SEL)] key for 1/2 second, then rotate
the DIAL knob to select the bandwidth for the VFO scanner. Now, press the [SCAN(SEL)]
key momentarily to initiate scanning toward a higher frequency. The transceiver will stop
when it receives a signal strong enough to break through the squelch threshold. The trans-
ceiver will then hold on that frequency according to the setting of the “Resume” mode
(Menu #37 (SCAN).
If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a
higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction
while the transceiver is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the [SCAN(SEL)] key (or the PTT key) again to stop scanning.
You may also initiate the scanner by pressing and holding in the microphone’s
[UP] or [DWN] key. However, in this case, the scanner will sweep frequencies
only on the current band. If you would like the scanner not to be restricted to the cur-
rent band, you may change Menu #46 (VFO.BND) to allow the scanner to hop to the
low edge of the next-highest band when the VFO frequency reaches the high end of the
current band (or vice- versa).

ADVANCED OPERATION BASIC OPERATION
TRANSMISSION
To transmit, simply close the PTT (Push To Talk)
switch on the microphone when the frequency is clear.
Hold the microphone approximately 25 mm (1”) from
your mouth, and speak into the microphone in a nor-
mal voice level. When your transmission is complete,
release the PTT switch; the transceiver will revert to
the receive mode.
When the RF power amplier heat sink rises to a factory preset temperature, the
transmit power level will be reduced to the “LOW” setting automatically to pre-
vent over-heating of the radio. If you leave transmit in this condition (even in the
“LOW” mode) for an extended period of time, the radio will be forced to return to the
receive mode.
Changing the Transmitter Power Level
You can select from among a total of four transmit power levels on your transceiver.
To change the power level, press the [LOW(ACC)]
keyto select one of four power settings. These power
levels will be stored, in memory registers, at the time
of memory storage.
During transmission, the Bar Graph will deect in the
display, according to the power output selected.

the squelch so that only signals exceeding a certain S-meter level will open the squelch.
To set up the RF Squelch circuit for operation, use the following procedure:
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #32 (RF SQL).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to select the desired signal strength
level for the squelch threshold (OFF , S-2, S-3, S-4,
S-5, S-6, S -7, S-8, S-9, or S-FULL).
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)] key for 1/2 second to exit to
normal operation.
5. Finally, rotate the SQL knob fully clockwise.
CHANNEL STEP SELECTION
The transceiver’s synthesizer provides the option of utilizing channel steps of 5/10/12.5/
15/20/25/50/100 kHz per step, as well as an automatic step selection based on the current
operating frequency (“AUTO”), any number of which may be important to your operating
requirements. The transceiver is set up at the factory in the “AUTO” conguration, which
probably is satisfactory for most operation. However, if you need to change the channel
step increments, the procedure to do so is very easy; remember to get set up on the de-
sired band before making any changes, as different steps may be programmed for each
operating band.
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #43 (STEP).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to select the new channel step size.
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)]
key for 1/2 second to exit to normal operation.
5 kHz and 15 kHz steps are not available for use on above 700 MHz.
RECEIVING MODE SELECTION
The transceiver provides for automatic mode change when the radio is tuned to different
operating frequencies. However, should an unusual receiving situation arise in which you
need to change to other receiving mode, the procedure to do so is very easy.
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #35 (RX MOD).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to select the desired receiving mode.
AUTO: Automatic mode setting per default values
for the selected frequency range
FM: Frequency Modulation (Narrow FM)
AM: Amplitude Modulation
4. Press the [BAND(SET)] key momentarily to save the new setting, then press and hold
in the [BAND(SET)] key for 1/2 second to exit to normal operation.
Unless you have a compelling reason to do so, leave the Automatic Mode Selec-
tion feature on so as to save time and trouble when changing bands. If you
make a mode change for a particular channel or station, you can always store that one
channel into memory, as the mode setting will be memorized along with the frequency
information.

REPEATER OPERATION REPEATER OPERATION
Repeater stations, usually located on mountaintops or other high locations, provide a dra-
matic extension of the communication range for low-powered hand-held or mobile trans-
ceivers. The transceiver includes a number of features which make repeater operation
simple and enjoyable.
REPEATER SHIFTS
Your transceiver has been congured, at the factory, for the repeater shifts customary in
your country.
Depending on the part of the band in which you are operating, the repeater shift may be
either downward (–) or upward (+), and one of these icons will appear at the top of the
LCD when repeater shifts have been enabled.
AUTOMATIC REPEATER SHIFT(ARS)
The transceiver provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be automatically applied whenever you tune into the desig-
nated repeater sub-bands in your country. These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #4 (ARS).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to change the setting to “ON” (to en-
able Automatic Repeater Shift).
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)]
key for 1/2 second to exit to normal operation.
With repeater shift activated, you can tem-
porarily reverse the transmit and receive
frequencies by pressing and holding in the
[TONE(HM/RV)] key for 1/2 second. Use
this feature to display the transmit frequen-
cy without transmitting, and to check the
strength of signals on a repeater uplink fre-
quency (so as to determine whether of not a
particular station is within “Simplex” range,
for example).

3. Press the [BAND(SET)] key momentarily, then ro-
tate the DIAL knob to select the desired shift among
“R P T. – ”,“R P T.+”, and “R P T. O F F.”
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)] key for 1/2 second to exit to
normal operation.
Changing the Default Repeater Shifts
If you travel to a different region, you may need to change the default repeater shift so as
to ensure compatibility with local operating requirements.
To do this, follow the procedure below:
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #39 (SHIFT).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to select the new repeater shift magni-
tude. The shift must be a multiple of 50 kHz.
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)]
key for 1/2 second to exit to normal operation.
If you just have one “odd” split that you need to program, don’t change the “de-
fault” repeated shifts using this Menu Item! Enter the transmit and receive fre-
quencies separately.

CTCSS/DCS OPERATION CTCSS/DCS OPERATION
CTCSS OPERATION
Many repeater systems require that a very-low-frequency audio tone be superimposed
on your FM carrier in order to activate the repeater. This helps prevent false activation of
the repeater by radar or spurious signals from other transmitters. This tone system, called
“CTCSS” (Continuous Tone Coded Squelch System), is included in your transceiver, and
is very easy to activate.
CTCSS setup involves two actions: setting the Tone Mode and then setting of the
Tone Frequency. These actions are set up by using the [TONE(REV)] key and
Set mode #44 (TN FRQ).
1. Press the [TONE(REV)] key several times, so that
“ENC” appears on the display; this activates the
CTCSS Encoder, which allows repeater access.
1) You may notice an additional “DCS” icon appearing while you press the
[TONE(REV)] key in this step. We’ll discuss the Digital Code Squelch system
shortly.
2) You may notice the “REV TN” indication on the display; this means that the Re-
verse Tone Squelch system is active, which mutes your transceiver’s receiver when it
receives a call from the radio sending a matched CTCSS tone. The “DEC” icon will
blink on the display when the Reverse Tone Squelch system is activated.
2. Pressing the [TONE(REV)] key once more in above step will cause “ENC DEC” to
appear. When “ENC DEC” appears, this means that the Tone Squelch system is active,
which mutes your transceiver’s receiver until it re-
ceives a call from another radio sending out a matching
CTCSS tone. This can help keep your radio quiet until
a specic call is received, which may be helpful while operating in congested areas.
3. When you have made your selection of the CTCSS
tone mode, press and hold in the [BAND(SET)] key
for 1/2 second to enter the Set mode, then rotate the
DIAL knob to select Menu #44 (TN FRQ). This Menu selection allows setting of the
CTCSS tone frequency to be used.
4. Press the [BAND(SET)] key momentari-
ly to enable adjustment of the CTCSS fre-
quency.
5. Rotate the
DIAL knob
until the
display indicates the Tone Frequency you
need to be using.
6. When you have made your selection, press

CTCSS OPERATION
the [BAND(SET)] key momentarily to save the new
setting, then press and hold in the [BAND(SET)] key
for 1/2 second to exit to normal operation.
Your repeater may or may not re-transmit a CTCSS tone - some systems just use
CTCSS to control access to the repeater, but don’t pass it along when transmit-
ting. If the S-Meter deflects, but the transceiver is not passing audio, press the
[TONE(REV)] key so that “ENC” appears - this will allow you to hear all trafc on the
channel being received.
DCS OPERATION
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your transceiver, and operation is
very similar to that just described for CTCSS. Your repeater system may be congured
for DCS;if not, it is frequently quite useful in Simplex operation if your friend(s) use
transceivers equipped with this advanced feature.
Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS
and that you select a Tone Code.
1. Press the [TONE(REV)] key until “DCS” appears on
the display; this activates the DCS Encoder/Decoder.
2. Now, press and hold in the [BAND(SET)] key for 1/2
second to enter the Set mode, then rotate the DIAL
knob to select Menu #9 (DCS.COD).
3. Press the [BAND(SET)] key momentarily to enable
the adjustment of the DCS code.
4. Rotate the DIAL knob to select the desired DCS Code
(a three-digit number).
5. When you have made your selection,
press the [BAND(SET)] key momentari-
ly to save the new setting, then press and
hold in the [BAND(SET)] key for 1/2
second to exit to normal operation.
Remember that the DCS is an Encode/Decode
system, so your receiver will remain muted
until a matching DCS code is received on an
incoming transmission. Switch the DCS off
when you’re just tuning around the band!

CTCSS/DCS OPERATION CTCSS/DCS OPERATION
TONE SEARCH SCANNING
In operating situations where you don’t know the CTCSS or DCS tone being used by an-
other station or stations, you can command the radio to listen to the incoming signal and
scan in search of the tone being used. Two things must be remembered in this regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-
sion). In the case of CTCSS, “ENC DEC” will appear on the display; in the case of
DCS, “DCS” will appear on the display.
2. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
3. Rotate the DIAL knob to select Menu #44 (TN FRQ)
when CTCSS is selected, or Menu #9 (DCS.COD)
during DCS operation.
4. Press the [BAND(SET)] key to enable adjustment of
the selected Menu Item.
5. Press the [SCAN(SEL)] key momentarily to start
scanning for the incoming CTCSS or DCS tone/code.
6. When the radio detects the correct tone or code, it
will halt on that tone/code, and audio will be allowed
to pass. Press the [BAND(SET)] key momentarily
to lock in that tone/code, then press and hold in the
[BAND(SET)] key for 1/2 second to save the new
setting and exit to normal operation.
If the Tone Scan feature does not detect a tone or code, it will continue to scan
indenitely. When this happens, it may be that the other station is not sending
any tone. You can press the [SCAN(SEL)] key to halt the scan at any time.
Tone Scanning works either in the VFO or Memory modes.
SPLIT TONE OPERATION
The transceiver can be operated in a Split Tone conguration via the Set mode.
1. Press and hold in the [BAND(SET)] key for 1/2 second to enter the Set mode.
2. Rotate the DIAL knob to select Menu #41 (SPLIT).
3. Press the [BAND(SET)] key momentarily, then rotate
the DIAL knob to select “ON” (to enable the Split
Tone feature).
4. Press the [BAND(SET)] key momentarily to save the
new setting, then press and hold in the [BAND(SET)]
key for 1/2 second to exit to normal operation.
When the Split Tone feature is activated, you can see the following additional parameters
after the “DCS” parameter while selecting the Tone Mode by pressing the [TONE(REV)]
key:
D: DCS Encode only (the “DCS” icon will blink during operation)
ENC DCS: Encodes a CTCSS Tone and Decodes a DCS code (the “DCS” and
“ENC” icons will appear during operation)
D-DEC: Encodes a DCS code and Decodes a CTCSS Tone (the “DCS” icon will
blink and the “DEC” icon will appear during operation)
Select the desired operating mode, from the selections shown above.

REGULAR MEMORY CHANNEL OPERATION
Memory Bank Recall
1. Set the radio to the Memory mode by pressing the [V/M(MW)] key, if necessary.
2. Press and hold in the [SCAN(SEL)] key for 1/2 sec-
ond, then rotate the DIAL knob to select the Memory
Bank (“BANK 1 ” ~ “BANK20”).
3. Press the [BAND(SET)] key momentarily to lock in the selected Memory Bank.
4. In the Memory Bank mode of operation, you can only select memory channels within
the current Memory Bank.
5. To change the Memory Bank to another Bank, press and hold in the [SCAN(SEL)]
key for 1/2 second; now rotate the DIAL knob to select the new Memory Bank, then
press the [BAND(SET)] key momentarily to lock in the new Memory Bank.
6. To exit from Memory Bank operation, press and hold
in the [SCAN(SEL)] key for 1/2 second, then rotate
the DIAL knob to select “NOBANK;” now press the
[BAND(SET)] key momentarily.
Deleting a Memory Channel from a Memory Bank
1. In the Memory Bank mode, recall the memory channel to be deleted from the Memo-
ry Bank.
2. Press and hold in the [SCAN(SEL)] key for 1/2 second, then press and hold in the
[V/M(MW)] key for 1/2 second. The channel will now be deleted from the Memory
Bank, but the memory register itself will still be available in the non-Bank mode.
Memory Only Mode
Once memory channel programming has been completed, you may place the radio in a
“Memory Only” mode, whereby VFO operation is impossible. This may be particularly
useful during public-service events where a number of operators may be using the radio
for rst time, and ultimate simplicity of channel selection is desired.
To place the radio into the Memory Only mode:
1. Turn the radio off.
2. Press and hold in the [MHz(PRI)] key while turning the radio on.
3. Rotate the DIAL knob to select the (F - 6 M - O NLY )
option, then press and hold in the [BAND(SET)] key
for 1/2 second.
To return to normal operation, repeat the above steps.

MEMORY OPERATION MEMORY OPERATION
HYPER MEMORY CHANNEL OPERATION
The transceiver usually stores, into memory, the operating frequency and some aspects of
operating status (such as VFO scan, CTCSS/DCS data, repeater shift, power level etc.).
However, the “Hyper Memory” Mode allows you to store the total current conguration
of the radio into a special “Hyper” memory bank.
Hyper Memory Storage
1. Set up the transceiver according to the desired
conguration.
2. Press and hold in, for two seconds, the Hyper
Memory key ([1] through [5]), corresponding to
the Hyper Memory channel into which you wish to
store this conguration.
Hyper Memory Recall
Press the appropriate Hyper Memory key ([1] through
[5]) to recall the desired Hyper Memory channel.
On Hyper Memory Channels “2” through
“5”, the current (original) conguration will
lost when you recall any other Hyper Memory Chan-
nel.To prevent this from happening, press and hold
in the (current) Hyper Memory key to store the current conguration into that Hyper
Memory Channel before recalling anothe Hyper Memory Channel, or set Menu #17
(HYPER) to enable the Automatic Writing feature for all Hyper Memories, including
Hyper Memory “1”.
WEATHER BROARDCAST CHANNEL OPERATION
The VHF Weather Broadcast Station Memory Channel Bank has been pre-programmed at
the factory, for quick selection of NOAA weather information stations.
1. Press and hold in the [LOW(ACC)] key for 1/2 sec-
ond to recall the Weather Broadcast Station Memory
Channel Bank.
2. Rotate the DIAL knob to select the desired Weather Broadcast channel.
3. If you wish to scan this bank to search for
louder stations, just press the PTT switch.
When the scanner pauses on a station, press the
PTT key once to halt the can, or press it twice
to restart the scan.
4. To exit to normal operation, press and hold in
the [LOW(ACC)] key for 1/2 second.
Severe Weather Alert
In the event of extreme weather disturbances, such as storms and hurricanes, the NOAA
(National Oceanic and Atmospheric Administration) sends a weather alert accompanied
by a 1050 Hz tone and subsequent weather report on one of the NOAA weather channels.
