microphone.
2. Dust the transceiver with an anti-pilling cloth to prevent bad contact.
3. When the transceiver is off work, please cover the microphone cap.
4. The buttons, control knob and the casing of transceiver are easy
to become dirty after long usage, you can use a neutral detergent
(do not use strong corrosive chemicals) and wrung damp cloth to
clean it.

update or recharging the battery.
Battery may not be installed correctly. Please
remove the battery and reload it.
Battery’s lifetime is due. Please update the
battery.
Battery is not charged fully, so please ensure
that the battery indicator is green when
removing it.
Make sure you are using the same frequency
and “sub-audio frequency/sub-audio digital
settings” as other members of the group.
Confirm whether you are in the valid range of
transceiver since other members of the group
may be too far away.
Please change the sub-audio frequency/sub-
audio digital settings. At this time, be sure to
change all the walkie-talkies of the group at
the same time. (Need dealers to rechange.)
Confirm whether the rotary volume knob is to
the appropriate volume.
Send the machine to dealers to check the
microphone.
Other members of the group may be too far
away and can not receive the voices you
send, please get close and try again.

User Security Information
Handheld transceiver product safety and RF
radiation
Warning: Please read the manual carefully before
using. It contains the important safety using operation
instruction, and RF energy and control information
contributing to meet the RF radiation limitation
requirement of national and international standards.
Information provided in this manual may replace the general safety
information of the editions before.

Handheld Transceiver Safety Guidelines and
Instruction
To control the transceiver radiation, ensure to meet the general or
non-controlled environment radiation limitation standard, please
operate following below procedures.
Press PTT key when talking; and release PTT key when receiving.
Because measured RF energy radiation will be generated when
transmitting, so transmitting time should not exceed 50% of the
using time.
Place the tranceiver vertically on the front, make sure the
microphone (and other parts including the antenna) is no less than
1 to 2 inches (ie 2.5 to 5cm) away from your lips when transmitting
signals. It is very important to keep the correct distance from the
transceiver, since the farther away the less radiation.
If you carry the portable transceiver around your body, please put
into SAMZUK specially designed fixture, leather, box or other annex. If
not, the body by radiation will be out of range of general or noncontrolled environment RF radiation limitation that required by
Radio Authority, Ministry of Information Industry.
If you do not use any accessories, not place the transceiver on the
front specified location, please make sure that it is no less than 1
inch (about 2.5cm) away from your body when transmitting signals.
It is very important to keep the correct distance from the transceiver,
since the farther away the less radiation.
Only use the certified and provision antenna, battery and
accessories or other alternatives by Samzuk. If not, the radiation will
be out of range of RF radiation that required by Radio Authority,
Ministry of Information Industry. Below web site lists the approved
parts and accessories by Samzuk

Voice compression and expansion
This feature ensures the user in a variety of noisy environments
can get a clear call. Set by the dealers in the channel through
programming software.
Scrambler
This feature is voice encryption, user no such feature can not
receive the real voice, so makes your call be kept confidential.
This feature may be set by dealers in the channel through
programming software.
DTMF encoding
This transceiver has DTMF encoding function. It can be set by
dealer througn programming software.
Remark: Electromagnetic Interference (EMI) occurs in nearly every
electronic equipment, by not enough shielding, improper design or
incorrect electromagnetic compatibility configuration.
Not allowed to change the transmitting frequency, to increase the
transmission power (including the installation of additional RF power
amplifier).
Not allowed to use an external antenna or other transmitting
antenna.
Shall not cause harmful interference to a variety of legitimate radio
services while using, if found harmful interference, should
immediately stop using, and to take measures to eliminate the
interference before continuing.
Prohibition of interconnection with the public telephone network,
public mobile communication network and other telecommunication
networks.
Place
To avoid electromagnetic interference and other problems caused
by electromagnetic incompatibility, please turn off the transceiver
in the place where there is a sign showing “No transceiver”.
Hospitals or medical institutions may use external RF energy very
sensitive equipment.
Prohibit the use of airports and aircraft radio.
