VX-800 OPERATING MANUAL
1
BEFORE YOU BEGIN
Battery Pack Installation and Removal
r To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the belt clip. Insert the battery pack into the battery compartment
on the back of the radio while tilting the Belt Clip
outward, then close the Battery Pack Latch until
it locks in place with a “Click.”
r To remove the battery, turn the radio off and re-
move any protective cases. Open the Battery Pack
Latch on the bottom of the radio, then slide the
battery downward and out from the radio while
unfolding the Belt Clip.
Do not attempt to open any of the rechargeable Lithium-Ion and Ni-Cd packs,
as they could explode if accidentally short-
circuited.
Low Battery Indication
r As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage reaches 6.0 volts, it is time to substitute a
freshly charged battery and recharge the depleted
pack. The LED indicator on the top of the radio
will blink red when the battery voltage is low (6
Volts or lower).
r Avoid recharging Ni-Cd batteries often with little
use between charges, as this can degrade the
charge capacity. We recommend that you carry
an extra, fully-charged pack with you so the operational battery may be used until depletion (this
“deep cycling” technique promotes better longterm battery capacity).
Notice !
There are no owner-serviceable parts inside the
transceiver. All service jobs must be referred to
an authorized Service
Representative. Consult your Authorized
Dealer for installation of
optional accessories.

ADVANCED OPERATION
Description of Operating Functions
Channel Scan
The Scanning feature is used to monitor multiple
signals programmed into the transceiver. While
scanning, the transceiver will check each channel
for the presence of a signal, and will stop on a channel if a signal is present.
One key or switch may be assigned to the Scan
function, as follows:
r One of the Soft keys may be assigned for Scan
operation; or
r The Toggle switch may have one position as-
signed to the Scan function.
To activate scanning:
l Press the assigned Soft key, or set the Toggle
switch to the assigned position.
l The scanner will search the channels, looking for
active ones; it will pause each time it finds a channel on which someone is speaking.
To stop scanning:
l Press the assigned Soft key, or set the Toggle
switch to a different position.
l Operation will revert to the channel to which the
CH knob is set.
Note: Your dealer may have programmed your radio
to stay on one of the following channels if you
press the PTT switch during scanning pause:
l Current channel (“Talk Back”)
l “Last Busy” channel
l “Priority” channel
l “Home” channel
l “Scan Start” channel
Dual Watch
The Dual Watch feature is similar to the Scan
feature, except that only two channels are monitored:
r The current operating channel; and
r The “Priority” channel.
To activate Dual Watch:
l Press the assigned Soft key, or set the Toggle
switch to the assigned position.
l The scanner will search the two channels; it will
pause each time it finds a channel on which
someone is speaking.
To stop scanning:
l Press the assigned Soft key, or set the Toggle
switch to a different position.
l Operation will revert to the channel to which
the CH knob is set.

VX-800 OPERATING MANUAL
ADVANCED OPERATION
High/Low Power
Press the assigned Soft key or switch the Toggle
Switch to the assigned position to set the radio’s
transmitter to the “Low Power” mode, thus extending battery life. Press the assigned Soft key
again or switch the Toggle Switch to the other
Position to return to “High Power” operation
when in difficult terrain.
Talk Around
Press the assigned Soft key or switch the Toggle
Switch to the assigned position to activate the Talk
Around feature when you are operating on duplex channel systems (separate receive and transmit frequencies, utilizing a “repeater” station).
The Talk Around feature allows you to bypass
the repeater station and talk directly to a station
that is nearby. This feature has no effect when
you are operating on “simplex” channels, where
the receive and transmit frequencies are already
the same.
Note that your dealer may have made provision
for “Talk Around” channels by programming “repeater” and “Talk Around” frequencies on two
adjacent channels. If so, the key may be used for
one of the other Pre-Programmed Functions.
VX-800 OPERATING MANUAL
TX Save Disable
Press the assigned Soft key or switch the Toggle
Switch to the assigned position to disable the Transmit Battery Saver, if you are operating in a location where high power is almost always needed.
The Transmit Battery Saver helps extend battery
life by reducing transmit power when a very
strong signal from an apparently nearby station
is being received. Under some circumstances,
though, your hand-held radio may not be heard
well at the other end of the communication path,
and high power may be necessary at all times.
LCD Invert
Press the assigned Soft key or switch the Toggle
Switch to the assigned position inverts the LCD
display to backward-facing readout (the backward
display is convenient for viewing when wearing
the transceiver on your belt). Press the assigned
Soft key again or switch the Toggle Switch to
the other Position-return the LCD display to
frontward-facing readout.
9
Encryption Disable
Press the assigned Soft key or switch the Toggle
Switch to the assigned position to turn off the optional voice encryption unit temporarily, for use
when an incorrect setting of (or failure in) the
encryption system at one end of the communication path has made it impossible to talk to the
other station.
Remember that disabling the encryption will mean
that your transmissions are no longer secure. Return to the encrypted mode as soon as possible, and
do not discuss any critical or confidential information while in the non-encrypted mode of operation.
Lock
Switch the Toggle Switch to lock the top-panel
keys; this can be enabled to prevent radio settings
from being disturbed.
Follow-Me Scan
“Follow-Me” Scan feature checks a User-assigned
Priority Channel regularly as you scan the other
channels. Thus, if only Channels 1, 3, and 5 (of
the 8 available channels) are designated for “Scanning,” the user may nonetheless assign Channel
2 as the “User-assigned” Priority Channel via the
10
ADVANCED OPERATION
“Follow-Me” feature.
To activate “Follow-Me” scanning, first select the
channel you want to designate as the “User-Assigned Priority Channel” and Switch the Toggle
Switch to the assigned position. Then turn the CH
selector knob to the “Scanning Start” channel
which has been programmed by your dealer to
activate the scanner. When the scanner stops on
an “Active” channel, the User-assigned Priority
Channel will automatically be checked every few
seconds; if activity is found on the User-assigned
Priority Channel, the radio will switch between
it and the Dealer-Assigned Priority Channel, if
any.
Follow-Me DW
To set up a “Dual Watch” frequency pair using the
“Follow-Me” feature, select a channel using the CH
selector knob. Now press the assigned Soft key;
pressing the assigned Soft key locks the current
channel as the User-assigned Priority Channel. Now
rotate the CH selector knob to another channel (not
the “Scanning Start” channel). Your radio will now
switch back-and-forth between the currently-selected channel (shown on the CH selector knob)
and the User-assigned Priority Channel.
VX-800 OPERATING MANUAL
ADVANCED OPERATION
During “Follow-Me” scanning (after you have
pressed the key), you can set up the “Dual Watch”
feature by rotating the CH selector knob to another channel. The radio will then scan back and
forth between the original User-assigned Priority
Channel and the newly-selected channel.
The Priority Channel you have assigned (before
pressing the key) will be retained in memory until you change it.
Channel Group Selection
The VX-800 is capable of separating its 200
memory channels into any of ten Groups. There
is no limit as to the number of channels which
may be assigned to each Group. The Dealer will
have made the Group assignment at the time of
channel programming. At the same time, one of
the Soft Keys will be assigned as the Channel
Group Selection key.
To change Channel Groups, press the assigned
soft key to step through the available Groups. Once
the desired Group is reached, rotate the CH selec-
tor knob to select the desired channel within the
selected Group.
You may wish to have the Scanner (described
VX-800 OPERATING MANUAL
previously) pass through more than one Group
during the scanning process (normally, scanning
is performed within the current group only). To
include the current Group in the scanning loop,
press and hold in the assigned Soft key for
one second.
To remove a Group from Group Scan, press and
hold in the assigned Soft key again for one second.
Multi-Group Scanning is only possible if you are
using the “User Scan” list.
The VX-800 has two scanning “lists:” the “Dealer
Scan” list and the “User Scan” list. The “Dealer
Scan” list is a fixed group of stations which will
be included when scanning is activated. The “User
Scan” list is a different list, initially arranged by
the Dealer, which may be modified by the User
(if, for example, you want to delete one or more
of these channels from the scanning list).
To edit the User Scan list, press and hold the soft
key (assigned to the Group Up/Down function)
to delete the current Memory Group from the
Scanning. Alternatively, press and hold the “Scan”
Soft key for one second to delete the Current
Memory channel from the Scanning.

ADVANCED OPERATION
When you delete a Group or channel, “-SKIP-”
will appear on the LCD for one second after pressing the Soft key. To restore a particular channel
to your scanning list, press and hold in the Soft
key again for one second; “-STOP-” will appear
on the LCD for one second after pressing the Soft
key.
This feature, if enabled, allows the user to change
the 3-digit Page Call code, used to call other similarly-equipped stations. Press the Dealer-assigned
soft key, followed by the three digits representing the Page Call code of the station you wish to
call. Three tones will be heard after the last key is
pressed (the new code will now be transmitted).
The receiver squelch of the other station will be
opened, and you can begin communication.
Your Dealer may have pre-programmed Auto-Dial
telephone number memories into your radio.
To dial a number, press the numbered key corresponding to the Auto-Dial memory number list
provided by your Dealer while pressing the PTT
switch. Once the telephone number has begun
(you will hear the tones in the speaker), you can
release the PTT switch.
Emergency
The VX-800 includes an “Emergency” feature
which may be useful if you have someone monitoring on the same frequency as your transceiver’s
channel. For further details contact your nearest
dealer..
VX-800 OPERATING MANUAL
ADVANCED OPERATION
ARTS (Auto Range Transpond System)
This system is designed to inform you when you and
another ARTS-equipped station are within communication range.
During ARTS operation, your radio automatically
transmits for about 1 second every 25 seconds (the
interval is programmed by the Dealer) in an attempt
to shake hands with the other station.
If you move out of range for more than two minutes,
your radio senses that no signal has been received, a
ringing beeper will sound, and "OUT OF SERVICE"
will scroll on the LCD. If you subsequently move
back into range, as soon as the other station transmits, your beeper will sound, and "IN SERVICE"
will scroll on the LCD.
DTMF Paging System
This system allows paging and selective calling, using DTMF tone sequences.
When your radio is paged by a station bearing a tone
sequence which matches yours, your radio's squelch
will open and the alert ringer will sound (unless you
have disabled it, as described previously).
The three-digit code of the station which paged you
will be displayed on your radio's LCD.
VX-800 OPERATING MANUAL

UNDERSTANDING RADIO WAVES
Radio waves travel from one point to another by several different means. The general term for these methods of wave travel is “propagation”. You may know
that “shortwave” signals can be propagated over distances of several thousand miles by reflection off of
the upper regions of the atmosphere.
Your hand-held transceiver, on the other hand, operates on the so-called VHF (Very-High Frequency)
or UHF (Ultra-High Frequency) bands. On these
bands, radio waves usually do not reflect off of the
atmosphere. Instead, the radio waves behave almost
as light: they travel in a straight line, and when they
meet a building or obstruction, they go no further in
that direction.
Therefore, it is important that you be as high and free
from obstructions as possible to cover the greatest distance when using your radio. If you operate from inside a car or building, any metal around you can absorb
much of the signal, both transmitted and received. Coverage may therefore be very poor under those conditions. However, if you must operate from indoors, moving next to a window will improve communications.
In view of the factors just discussed, you can easily see
the potential benefit of holding the radio up high near
your mouth while transmitting. In this way the antenna
14
is high and clear, and coverage is best.
On final note regarding propagation is useful in im-
proving coverage. Because radio waves at VHF/UHF
are similar to light waves, they do reflect, to varying
degrees, off of hills, buildings, and the like. In a crowded
urban area, with many close buildings close together,
many reflections may occur, and interfere with one
another, causing variations in signal strength at different locations.
Therefore, if a signal is weak and you walk a few feet
in any direction, reception may suddenly become clear,
because a particular reflection path may become dominant. Reflections are frequently useful, as they can allow for communications between two stations over a
highly obstructed path.
