This manual provides technical information necessary for servicing the VX-160V and VX-180V FM Trans-
Servicing this equipment requires expertise in handling surface-mount chip components. Attempts by non-
qualified persons to service this equipment may result in permanent damage not covered by the warranty,
and may be illegal in some countries.
Two PCB layout diagrams are provided for each double-sided circuit board in the transceiver. Each side of
is referred to by the type of the majority of components installed on that side (“leaded” or “chip-only”). In
most cases one side has only chip components, and the other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
While we believe the technical information in this manual to be correct, VERTEX STANDARD assumes no
liability for damage that may occur as a result of typographical or other errors that may be present. Your
cooperation in pointing out any inconsistencies in the technical information would be appreciated.

Battery Pack Installation and Removal
U 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

U To remove the battery, turn the radio off and remove
any protective cases. Open the Battery Pack latch on
the bottom of the radio, then slide the battery down-
ward and out from the radio while holding the Belt
Do not attempt to open any of the rechargeable Ni-
Cd packs, as they could explode if accidentally short-
Low Battery Indication
U As the battery discharges during use, the voltage gradu-
ally 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 (on the VX-180, the “ ”
icon will appear on the LCD) when the battery voltage
is low.
U Avoid recharging Ni-Cd batteries often with little use
between charges, as this can degrade the charge capac-
ity. 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).

Operating Manual Reprint
Preliminary Steps
U Install a charged battery pack onto the transceiver, as
described previously.
U Screw the supplied antenna onto the Antenna jack.
Never attempt to operate this transceiver without an
antenna connected.
U If you have a Speaker/Microphone, we recommend that
it not be connected until you are familiar with the ba-
sic operation of the VX-160/-180.
Operation Quick Start
U Turn the top panel’s VOL/
PWR knob clockwise to turn
on the radio on.
U Turn the top panel’s CH selec-
tor knob to choose the desired
operating channel.
U Rotate the VOL/PWR knob to
set the volume level. If no sig-
nal is present, press and hold
in the MONITOR key (the
lower button on the left side)
for more than 1 seconds; back-
ground noise will now be heard, and you may use this
to set the VOL/PWR knob for the desired audio level.
U Press and hold in the MONI-
TOR key for more than 1 sec-
onds (or press the MONITOR
key twice) to quiet the noise
and resume normal (quiet)
U 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.
U If a Speaker/Microphone is available, remove the plas-
tic cap and its two mounting screws from the right side
of the transceiver, then insert the plug from the Speaker/
Microphone into the MIC/SP jack; secure the plug us-
ing the screws supplied with the Speaker/Microphone.
Hold the speaker grille up next to your ear while re-
ceiving. 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 us-
ing the Speaker/Microphone.

K F nctKey Functions F nK ct Key Functions
The VX-180 provides programmable [ A], [B], and [C]
function keys, and both the VX-160 and VX-180 provide
programmable MONITOR keys. These “ Soft” keys func-
tions can be customized (set to other functions), via pro-
gramming by your VERTEX STANDARD dealer, to meet
your communications/network requirements. Some fea-
tures may require the purchase and installation of optional
internal accessories. The possible Soft key programming
features are illustrated at the right, and their functions are
explained in the next chapter. For further details, contact
your VERTEX STANDARD dealer.
For future reference, check the box next to each function
that has been assigned to the Soft key on your particular
radio, and keep it handy.
