INTRODUCTION
Thank you for purchasing this M-Tech product.
The MT-V82N VHF Transceivers are designed
and built with M-Tech’s superior technology and
craftsmanship. With proper care, this product should
provide you with years of trouble-free operation.
This document is the operating guide for the
MT-V82N VHF Transceiver.
1.1 Important
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL - This instruction
manual contains important operating instructions
for the MT-V82N.
1.2 Explicit defi nitions
Word Defi nition
WARNING! Personal injury, fi re hazard or
electric shock may occur.
CAUTION! Equipment damage may occur.
NOTE Recommended for optimum use.
No risk of personal injury, fi re or
electric shock.
1.3 Precautions
WARNING! NEVER hold the transceiver so that
the antenna is very close to, or touching exposed
parts of the body, especially the face or eyes, while
transmitting. The transceiver will perform best if the
microphone is 5 to 10 cm (2 to 4 inches) away from
the lips and the transceiver is vertical.
WARNING! NEVER operate the transceiver with
a headset or other audio accessories at high
volume levels.
4
SECTION 1
SECTION 1

INTRODUCTION
Hearing experts advise against continuous high
volume operation. If you experience a ringing in
your ears, reduce the volume or discontinue use.
NEVER connect the transceiver to a power source
that is DC fused at more than 5 A. Accidental reverse
connection will be protected by this fuse, but higher
fuse values will not give any protection against such
accidents and the transceiver will be ruined.
NEVER attempt to charge alkaline or dry cell
batteries. Be aware that external DC power
connections will charge batteries inside the battery
case. This will damage not only the battery case
but also the transceiver.
DO NOT push the PTT when not actually desiring to
transmit. Place the unit in a secure place to avoid
inadvertent use by children.
DO NOT operate the transceiver near unshielded
electrical blasting caps or in an explosive
atmosphere.
AVOID using or placing the transceiver in direct
sunlight or in areas with temperatures below -10°C
(+14˚F) or above +60°C (+140˚F).
The use of non M-Tech battery packs/chargers may
impair transceiver performance and invalidate the
warranty.
Even when the transceiver power is OFF, a slight
current still fl ows in the circuits. Remove the
battery pack or case from the transceiver when
not using it for a long time. Otherwise, the battery
pack or installed rechargeable batteries will
become exhausted.
For USA only:
Caution: Changes or modifi cations to this
transceiver, not expressly approved by M-Tech
Dynamic Corporation Limited, could void your
authority to operate this transceiver under FCC
regulations.

INTRODUCTION
1.4 Safety training information
CAUTION
To ensure that your exposure to RF electromagnetic
energy is within the FCC allowable limits, always
adhere to the following guidelines:
• DO NOT operate the radio without a proper
antenna attached, as this may damage the
radio and may also cause you to exceed FCC RF
exposure limits. A proper antenna is the antenna
supplied with this radio by the manufacturer
or an antenna specifi cally authorized by the
manufacturer for use with this radio.
• 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 “Tx indicator”
appears. You can cause the radio to transmit by
pressing the “PTT” switch.
• ALWAYS use M-Tech authorized accessories
(antennas, batteries, belt clips, speaker/mics, etc.).
Use of unauthorized accessories can cause the
FCC RF exposure compliance requirements to be
exceeded.
• ALWAYS keep the antenna at least 2.5 cm (1 inch)
away from the body when transmitting, and only
use the M-Tech belt-clips which are listed in this
manual when attaching the radio to your belt, etc.
To provide the recipients of your transmission the
best sound quality, hold the transceiver at least 5
cm (2 inches) from your mouth, and turned slightly
to one side. The information listed above provides
the user with the information needed to make him
or her aware of RF exposure, and what to do to
assure that this radio operates within the FCC RF
exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your M-Tech radio generates
RF energy that can possibly cause interference
with other devices or systems. To avoid such
6
SECTION 1
SECTION 1

interference, turn off the radio in areas where
signs are posted to do so. DO NOT operate
the transmitter in areas that are sensitive to
electromagnetic radiation such as hospitals,
aircraft, and blasting sites.

2.1 Preparation
Battery pack replacement
Before replacing the battery pack, push and hold
[PWR] for 1 sec. to turn the power OFF.
• Slide the battery release forward, then pull the
battery pack upward with the transceiver facing
away from you.
Charging with the BC-82S
The BC-82S provides rapid charging battery
pack with or without a transceiver attached. The
following is additionally required:
• An optional AC adapter PA-82E (the adapter/
spacer is supplied with BC-82S).
Check orientation
for correct charging.
(Insert together with
the adapter/spacer.)

QUICK GUIDE
About the adapter/spacer
The adapter (Spacer A) only is required for MT-V82N.
When removing the spacer (Spacer B/C), push the
latch carefully with your fi nger to remove the spacer
(Spacer B/C) from the adapter (Spacer A).
Remove the spacer (Spacer B/C)
from the adapter.
CAUTION!
•DO NOT push or force the latch with a screw
driver, etc., to remove it.
•DO NOT bend the latch when the adapter
and spacer are not joined together. This will
cause weakening of the latch plastic.
• Both cases may break the latch and it may
not be able to be reattached.
Antenna
Attach the antenna
to the transceiver as
illustrated at right.
Push the latch
carefully.

2.2 Your fi rst contact
Now that you have your MT-V82N ready, you are
excited to get on the air. We would like to walk you
through a few basic operational steps to make
your fi rst “On The Air” use an enjoyable experience.
About default setting
The [VOL] control function can be exchanged with
[▲]/[▼] keys function in INITIAL SET MODE. However,
in this QUICK GUIDE, the factory default setting
([VOL] controls audio output level) is used to simplify
instructions.
Basic operation
1. Turning ON the transceiver
Although you have purchased
a brand new transceiver, some
settings may be changed from the
factory defaults because of the
Quality Control process. Resetting
the CPU is necessary to start from
factory default.
➥ While pushing [MONI] and [D•CLR], push and hold
[PWR] for 1 sec. to reset the CPU and turn power
ON.
2. Adjusting audio output level
➥Rotate
[VOL] to set the desired audio level.
3. Adjusting the squelch level
➥ While pushing and holding
[MONI], push [▲] or [▼] to set the
squelch level.
4. Tune the desired frequency
The up/down keys, [▲]/[▼], will
allow you to tune to the frequency
that you want to operate on.
Page 27 will instruct you on
how to adjust the tuning step size.
➥ Push [▲] or [▼] to adjust the
frequency.

5. Transmit and receive
➥ Push and hold [PTT] to transmit, then speak into
the microphone; release to receive.
2.3 Repeater operation
1. Setting duplex
➥ Push [A•FUNC], then [4•DUP]
several times to select minus
duplex or plus duplex.
QUICK GUIDE
Direct frequency input from the keypad is also
available.
➥ To enter the desired
frequency, enter 6 digits
starting from the 100 MHz
digit.
• Entering three to fi ve digits
then pushing [✱•ENT ]will
also set the frequency.
• When a digit is mistakenly
input, push [D.CLR] to abort
input.
