Operation
Preliminary Steps
Ì Press and hold in the Soft key assigned to “MONITOR” for more
than 1 seconds (or press the
MONITOR key twice) to quiet
the noise and resume normal
(quiet) monitoring.
Operation Quick Start
Ì To transmit, monitor the channel
and make sure it is clear.
THIS IS AN FCC REQUIRMENT!
Ì To transmit, press and hold in the
PTT switch. Speak into the microphone area of the front panel
grille (lower left-hand corner) in
a normal voice level. To return to
the Receive mode, release the PTT switch.
Ì Install a charged battery pack onto the transceiver, as described
previously.
Ì Screw the supplied antenna onto the Antenna jack. Never attempt to operate this transceiver without an antenna connected.
Ì If you have a Speaker/Microphone, we recommend that it not
be connected until you are familiar with the basic operation
of the VX-410E/-420E.
Ì Turn the top panel’s VOL/PWR
knob clockwise to turn on the radio on.

Inportant Notice!
H Please read this manual carefully to become familiar with
the features of this transceiver.
H When transmitting, hold the radio in a vertical position
with its microphone 2.5 to 5 cm away from your mouth
and keep the antenna at least 2.5cm away from your head
and body.
H The radio must be used with a maximum operating duty
cycle not exceeding 50 %, in typical Push-to-Talk (PTT)
configurations. DO NOT transmit for more than 50 % of
total radio use time (50 % duty cycle). Transmitting more
than 50 % of the time can cause FCC RF exposure compliance requirements to be exceeded.
The radio is transmitting when the red LED on the top of
the radio is illuminated. You can cause the radio to transmit by pressing the PTT button or by using the VOX
headset, model VC-25.
H DO NOT transmit when the radio is used in Body Worn
configuration with the following accessory: belt-clip.
It must be used ONLY for (1) there is a 4 cm distance
from the body during transmitting, (2) monitoring purposes, using the speaker only and (3) for carrying purposes.
H Always use Vertex Standard authorized accessories.
Notice !
There are no owner-serviceable parts inside the transceiver.
All service jobs must be referred to an authorized VERTEX STANDARD Service Representative. Consult your Authorized VERTEX STANDARD Dealer for installation of
optional accessories.
Ì As the battery discharges during use, the voltage gradually
becomes lower. When the battery voltage becomes to low,
substitute a freshly charged battery and recharge the depleted
pack. The TX/BUSY indicator on the top of the radio will
blink red when the battery voltage is low.
Ì 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 long-term battery capacity).
Ì Rotate the VOL/PWR knob to set
the volume level. If no signal is
present, press and hold in the Soft
key assigned to “MONITOR” for
more than 1 seconds; background
noise will now be heard, and you
may use this to set the VOL/PWR
knob for the desired audio level.

with the Speaker/Microphone. Hold the speaker grille up next
to your ear while receiving. To transmit, press the PTT switch
on the Speaker/Microphone, just as you would on the main
transceiver’s body.
Note:Save the original plastic cap and its mounting screws.
They should be re-installed when not using the Speaker/

“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 as the
“User-assigned” Priority Channel via the “Follow-Me” feature.
Press the assigned Soft key to activate “Follow-Me” scanning,
then turn the CH selector knob to the channel which you want to
designate as the “User-Assigned Priority Channel”. When the
scanner stops on an “active” channel, the User-assigned Priority
Channel will automatically be checked every few seconds.

assigned Soft key to resume normal (quiet) Noise and Tone
squelch action.
Low Power
Press (or Press and hold) the assigned Soft key to set the radio’s
transmitter to the “Low Power” mode, thus extending battery
life. Press (or Press and hold) the assigned Soft key again to
return to “High Power” operation when in difficult terrain.
When the radio’s transmitter is set to “Low Power” mode, the
“Low” icon will be indicated on the display.
Follow-Me Scan
Talk Around
Press (or Press and hold) the assigned Soft key 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.
When the “TA” function is activated, the “ ” icon will be indicated on the display.
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.
Add/Del
The Add/Del feature allows the user to arrange a custom Scan.
Press (or Press and hold) the assigned Soft key to delete/restore
the current channel to/from your scanning list.

one second after pressing the Soft key.
TX Save Off
Press (or Press and hold) the assigned Soft key 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

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.
Call 1, 2, 3/Reset
When the 2-tone or 5-Tone selective calling unit is installed, press
(or Press and hold) the assigned Soft key to silence the receiver
and reset for another call, when a communication is finished.

If you have out of range for more than two minutes, your radio
senses that no signal has been receives, a ringing beeper will
sound, and “IN RANGE” will appear on the LCD. If you subsequently move back into range, as soon as the other station transmits, your beeper will sound and “OUT RANGE” will appear on
the LCD.
DTMF Paging System (VX-420E only)
This system allows paging and selective calling, using DTMF
tone sequences.
When your radio is paged by a station bearing a tone sequence
