Warning：
Your radio generates RF electromagnetic energy during transmit mode. This radio is designed for
and classified as "ccupational Use Only" meaning it must be used only during the course of
employment by individuals aware of the hazards, and the ways to minimize such hazards. This
radio is NOT intended for use by the "eneral Population"in an uncontrolled environment.
This radio has been tested and complies with the FCC RF exposure limits for "ccupational Use
Only" In addition, your SHENZHEN COVALUE COMMUNICATIONS CO.,LTD.radio complies
with the following Standards and Guidelines with regard to RF energy and electromagnetic energy
levels and evaluation of such levels for exposure to humans:
1. FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
2. American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with
Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
3. American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the
Measurement of Potentially Hazardous Electromagnetic Fields- RF and Microwave.

4. The following accessories are authorized for use with this product. Use of accessories other than
those (listed in the instruction) specified may result in RF exposure levels exceed the FCC
requirements for wireless RF exposure.
To ensure that your expose to RF electromagnetic energy is within
the FCC allowable limits for occupational use, always adhere to the following guidelines:
1. DO NOT operate the radio without a proper antenna attached, as this may damaged 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 antenna specifically authorized by the
manufacturer for use with this radio.
2. DO NOT transmits 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” lights red. You can cause the radio to transmit
by pressing the “PTT” switch.
3. ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and
only use the COVALUE belt-clip which is listed in instructions when attaching the radio to your
belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the
recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches)
from your mouth, and slightly off 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 as*sure that this radio operates with the FCC RF
exposure limits of this radio. Electromagnetic Interference/Compatibility During transmissions,
your COVALUE radio generates RF energy that can possibly cause interference with other devices
or systems. To avoid such 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.
Occupational/Controlled Use The radio transmitter is used in situations in which persons are
exposed as consequence of their employment provided those persons are fully aware of the
potential for exposure and can exercise control over their exposure.

2、Getting started
2.1 Charging the Battery
Plug the power adapter into the proper AC wall outlet; and insert the DC plug in the charger coup.
The Red LED flashes after it enters normal work. (Red LED lights per 4.5 seconds)
Insert the battery or the radio to be charged into the charger slot. Please turn off the radio before

insert it into the charger.
Make sure the battery is in good contact with the charger terminals. When the red indicator is
lighted, the charger begins to charge the battery.
After charging for about 3 hours, the red LED will turn OFF and the green LED will light
indicating the battery has been fully charged.
On the first charge, please leave the battery in that state of green indicator for 1~2 hours before
you remove it from the charger to achieve the best performance of the battery. Then you can
disconnect the power adapter from the AC outlet.
If the Red LED flashes quickly (0.2s on 0.2s off), this means the charging process stopped, This
could be because the charging temperature is too high or the battery has a problem, the charger
enters a protective state and no more charge is delivered to the battery. Please stop charging in
such situation and remove the battery from the charger.

the radio for the first time.
* The radio is supplied with a standard battery manufactured by the factory.
* When you charge the battery for the first time after purchasing or after a long time storage (over
2 months), you should repeat charging it several times to achieve the normal battery capacity.
* Do not recharge the battery after it has been fully charged or it is partially discharged, otherwise
it might affect the battery life or performance. Remove the battery from the charger after
charging is finished.
* If the radio enters low Battery warning state, please recharge the battery. Do not use the radio in
low power state, which will affect the battery life and performance.

■Radio Setting
TOT (Time-out Timer)
1) TOT dispatch time
The TOT Dispatch Time is the maximum period of time that the radio is allowed to transmit
continuously in normal dispatch mode. When the programmed time expires, the radio generates a
warning tone and stops transmitting. The range for the TOT Dispatch Time is from 5 seconds to
600 seconds in step of 5 seconds..
2) TOT Re-key
a) TOT re-key specifies the time when transmission is prohibited after the time-out timer is
activated.
b) During the time of transmitting prohibition, if you press the PTT button, warning tone sounds
and transmitting is prohibited.
3) TOT Pre-alert
a) Before the time-out timer stops transmitting, the radio sounds pre-alert tone.
b) After the alarm tone, if the transmitting time is longer than the preset time limit, the time-out
timer will be activated.
4) TOT Reset
a) TOT Reset is the delay time between releasing the PTT button and resetting the time-out
timer.
b) If the time of releasing the PTT button is shorter than the TOT Reset, the countdown of
transmitting prohibition will continue.
Battery Save
The dealer can program the battery save type.
If the battery save function has been set, 10 seconds after no signals being received or no
operations being conducted, the radio enters the battery save mode. It will exit the battery save
mode automatically after receiving signals or being conducted.
Battery Save Types: Short, Middle, Long and OFF.
Battery save function can increase battery active time.
Low Battery Warning
Low Battery warning tone sounds and RED LED flashes when the battery power goes below the
preset value and you need to recharge the battery. If the battery voltage is too low, transmission is
prohibited.

CTCSS/DCS
The dealer can set CTCSS/DCS on the radio channels to ignore calls on the same channel from
irrelevant radios.
If a channel has been set with CTCSS/DCS, the squelch will be activated only when it receives the
proper CTCSS/DCS signals. And only the radios set with the same CTCSS/DCS signaling as
those on yours can hear your call.
Note: Using a CTCSS/DCS channel doesn’t mean your calls are private. If the CTCSS/DCS tones
of other radios are identical with those on yours, they can hear your calls.
■User Template
A user template includes PTT code-transmitting, encoding, decoding, Busy Channel Lockout, Call
1/2/3/4, RX squelch mode, TX conditions and decoding conditions, etc. Maximum 16 user
templates are available on this radio.
RX Squelch Mode
The dealer can set conditions under which the speaker will be activated from the following 4
options:
1) CTCSS/DCS and Audio Squelch: The speaker will be activated only when both CTCSS/DCS
and the selective signaling matched.
2) Audio Squelch: The speaker will be activated when the selective signaling matched.
3) CTCSS/DCS Squelch: The speaker will be activated when CTCSS/DCS matched.
4) Carrier Squelch: The speaker will be activated when carrier wave presents
Scan
When in scanning, the radio checks signals on each channel; it stops scanning and pauses on the
channel on which signals are detected until the signals disappear. If a delay time has been set
between the interval of signal disappearing and scanning restarting, the radio will
stay on that channel if it receives any signals during the delay time.
The operating channel of the radio will revert to the following channels automatically when you
press PTT button during scanning. The dealer can select one among the following six options.:
1) Start channel
