should replace the pack with a new one.
1. Install the FNB-80LI as shown in the illustration.
2. Close the Battery Pack Latch on the bottom of the radio.
Do not attempt to open any of the rechargeable LI-ion packs, as personal injury or
damage to the LI-ion pack could occur if a cell or cells become accidentally short-
circuited.
Battery Charging
Battery ChargingBattery Charging
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by
connecting the NC-72B/C Battery Charger, as shown in the illustration, to the EXT DC
jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B or E-DC-6 DC
Adapter (with its cigarette lighter plug) may also be used for charging the battery, as
shown in the illustration.
The “Now Charging . . .” will blink in the display while the battery is being charged.
When charging is finished, the display will change to indicate “Complete” and the
BUSY/TX indicator will blink blue.
Important Notes:
The NC-72B/C is not designed to power the transceiver for operation (reception or
transmission).
Do not leave the charger connected to the transceiver for continuous periods in
excess of 24 hours. Long term overcharging can degrade the LI-ion battery pack
and significantly shorten its useful life.
If using a charger other than the NC-72B/C, or if using a battery pack other than

Installation of FBA-23 Alkaline Battery Case (Option)
The optional FBA-23 Battery Case allows receive monitoring using two “AA” size
Alkaline batteries. Alkaline batteries can also be used for transmission in an emergency,
but power output will only be ??? mW, and battery life will be shortened dramatically.
To Install Alkaline Batteries into the FBA-23
1. Slide the batteries into the FBA-23 as shown in the illustration, with the Negative
[–] side of the batteries touching the spring connections inside the FBA-23.
2. Open the Battery Pack Latch on the bottom of the radio.
3. Install the FBA-23 as shown in the illustration, with the [+] side facing the bottom
of the transceiver.
4. Close the Battery Pack Latch on the bottom of the radio.
The FBA-23 does not provide connections for charging, since Alkaline cells cannot be
re-charged. Therefore, the NC-72B/C, E-DC-5B, or E-DC-6 may safely be connected to
the EXT DC jack when the FBA-23 is installed.
Notes:
•The FBA-23 is designed for use only with AA-type Alkaline cells.
•If you do not use the VXA-700 for a long time, remove the Alkaline batteries from
the FBA-23, as battery leakage could cause damage to the FBA-23 and/or the
transceiver.

Scanning Operation
Scanning OperationScanning Operation
Scanning Operation
Basic Scan
Basic ScanBasic Scan
Basic Scan
The VXA-700 allows you to scan automatically in the VFO*1, Main Memory, “Book”
Memory, or Weather Channel*2 modes. It pauses on signals encountered, so you can talk
to the station(s) on that frequency, if you like.
*1: In the VFO mode, the automatic scanner is only available in the current operating
band (AIR band, 2-m Amateur band, or FM BC band). Furthermore, on the AIR
band, the automatic scanner is only available in the COM band (118.000 - 136.975
MHz); when the scanner reaches the uppermost frequency in the COM band, it will
revert to the bottom end of the COM band and repeat the scanning process until
you cancel the scanning process.
*2: USA version only.
If you wish to scan in the NAV band (108.000 - 117.975 MHz), you can do so manually, as
described below.
Scanning operation is basically the same in each of the above modes.
Press the [SCAN(DW)MT] key momentarily to start the automatic scanner upward
(toward a higher frequency or a higher channel number).
When the scanner encounters a signal, scanning pauses and the radio remains on
that channel until one second after the signal disappears, after which scanning will
resume.
While the scanner remains paused on a frequency, the decimal point of the
frequency display blinks. The display will be illuminated unless the Scan Lamp
Feature is turned off.
To change the scan direction, turn the DIAL selector knob one click in the opposite
direction.
To stop the automatic scanner, press the PTT switch or the [SCAN(DW)MT] key
momentarily.

The VXA-700’s automatic scanner is not operational in the NAV band (108.000 - 117.975
MHz), because the NAV stations (ILS, etc.) transmit constantly (thereby causing the
scanner to stop repeatedly). However, you can scan manually in the NAV band, per the
following procedure:
Press and hold the [SCAN(DW)MT] key to start the manual scanner. Scanning will
continue as long as the key is depressed.
Release the [SCAN(DW)MT] key to stop the manual scanner immediately.
Note: When scanning upward in frequency, when the frequency reaches the COM Band
(118.000 - 136.975 MHz) via manual scanning, The VXA-700 will switch to the
automatic scanner mode.
Channel-Skip Scanning
Channel-Skip ScanningChannel-Skip Scanning
Channel-Skip Scanning
Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or
Weather Broadcast stations inhibit scanner operation. Since these stations are always
active, the scanner will be halted repeatedly on their channels. Such channels can be set
to be “Skipped” during Memory scanning (MR, Book or WX modes), if you like, so as not
to interfere with automatic channel scanning:
Recall the Memory Channel to be skipped during scanning.
Press and hold the [9(SK)] key for 3 seconds. The “W” icon will appear at the right of
the frequency display, indicating that the channel is to be ignored during scanning.
You can also designate a channel to be skipped while scanning. When the receiver is
halted on a channel that you wish to skip, press and hold the [SCAN(DW)MT] key
for 2 seconds (the icon will appear next to the channel to be skipped).
Later, to re-enable the memory channel for scanning, repeat the first two steps. The
“W” icon will disappear by the channel you have just re-enabled.
Note: A memory set to be “Skipped” is still accessible for manual memory selection using
the DIAL selector knob.
Dual Watch Operation
Dual Watch OperationDual Watch Operation
Dual Watch Operation
The Dual Watch feature automatically checks for activity on a “Priority” channel* while
you are operating on another channel. During Dual Watch operation, the current
channel and the Priority channel will each be polled for a 500 ms interval, as the VXA-
700 looks for activity on each channel.
To start Dual Watch, press [F] ´[SCAN(DW)MT].
The “DW” icon will appear on the display.
While receiving on the “current” channel (not the Priority channel), you may push

the PTT switch at any time to transmit on that channel.
When a signal is received on the Priority channel, operation immediately shifts to
the Priority channel, the “DW” icon will blink, and the display will become
illuminated.
While receiving on the priority channel, if you momentarily press the PTT switch,
Dual Watch will be disabled. You may then transmit on the Priority Channel.
To stop Dual Watch, press [F] ´[SCAN(DW)MT].
If you wish, you may use both the Dual Watch and Scan features simultaneously. To
do this, start the Dual Watch first, then start the Scanner.
*The “Priority” channel is defined as the last-used Memory Channel (when using the
VFO and “Book” memory modes) or Memory Channel “1” (when using the Main Memory
mode).
Priority Dual Watch Operation
Priority Dual Watch OperationPriority Dual Watch Operation
Priority Dual Watch Operation
Similar to Dual Watch operation (described on previous page), Priority Dual Watch is an
enhanced version which includes the following additional features:
The receiving time interval (ratio) between the current channel and the Priority
channel may be customized via the Menu Item “PRI Time.” See page ?? for details.
Irrespective of which channel is currently being received, when the PTT button is
pushed transmission will always occur on the Priority channel.
Before initiating Priority Dual Watch, Menu Item “DW/PRI” must be set to the “PRI”
mode (instead of “DW”). See page ?? for details.
To start Priority Dual Watch, press [F] ´[SCAN(DW)MT]. The “DW” icon will
appear on the display.
While receiving on the “current” (non-Priority) channel, pressing the PTT button
once causes the radio to switch to the Priority channel and cancels Dual Watch.
Press the PTT button again to transmit on the Priority channel.
When a signal is received on the Priority channel, reception immediately shifts to
the Priority channel, the “DW” icon will blink, and the display will become
illuminated unless the Scan Lamp Feature is turned off.
While receiving on the priority channel, if you momentarily press the PTT switch,
Priority Dual Watch will be disabled. You may then transmit on the Priority
Channel.
