

 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.

 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.

 ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting and only use the HYT 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.

antenna farther away from you head

Notices to the user

. Government law prohibits the operation of unlicensed radio transmitters within the territories

under government control.

. Illegal operation is punishable by fine or imprisonment or both.

. Refer service to qualified technicians Only.

. It is important that the operator is aware of and understand hazards common to the operation of

any transceiver. Explosive environment (such as gases, dust, fumes), turn off your transceiver

while talking on fuel, or while parked in gasoline service stations.

Measures:

. Reorient or relocate the receiving antenna.

. Increasing separation between the equipment and receiver.

. Connect the equipment into and outlet on a circuit different from that to which the receiver is

connected.

. Consult the dealer or and experienced radio/TV technician for help.

Precautions

Only qualified technicians are allowed to maintain this product

Do not use the radio or charge a battery in explosive areas such as coal gas, dust , steam, etc.

Working with repeater

This series of transceiver is available to work with the repeater both in frequency mode and

channel mode, which is programmable through the key board and via the programming software.

Please refer to the following steps about manually programming the channels to work the repeater.

a. set the transceiver work in the frequency/VFO mode, (if the radio work on channel mode,

please press key to switch frequency mode )

b. Input the receive frequency through the keyboard. ( the receive frequency of this transceiver is

the transmit frequency of repeater)

c. Set the related parameter you need for this frequency, like MENU15-18 CTCDD/DCS,

MENU 26 Offset frequency, MENU 27 shift frequency direction and others.

d. Memorize this frequency and the parameter into the specified channel by MENU 30.

e. After setting the Offset frequency and the shift frequency direction of receiving memory, you

do not need to memorize the transmit frequency.

After above, the settings to work with repeater are successful. Switch the working mode to

channel mode, call out this specified channel you have memorized, the transceiver can join in the

repeater.

For example, the receive frequency range of repeater is 442.850MHz, the offset frequency is

5.00MHz, the shift frequency direction is “-“, the T-CTCSS is 103.5hz, the specified channel

CH-20. Please see the steps as following:

a. Power on the transceiver, and set it to work in frequency mode.

b. Press to set the frequency step, turn encode knob to select the desired

frequency step, and then press to confirm, finally press to return to standby.

c. Input the frequency447.850 through the keypad, and operate as follows:

Press to set the transmitting power. Turn encode key to

select the desired power, and then press to confirm, finally press to return to

standby. (Please refer to MENU 4 on page 16)

Press to set the T-CTCSS, turn encode key to select the desired

CTCSS code 103.5HZ, and then press to confirm, finally press to return to standby.

(Please refer to MENU 16 on page 23)

Press to set the offset frequency, turn encode knob to select the

desired offset frequency 5.00 MHz, and then press to confirm, finally press to return

Press to set the shift frequency direction. Turn encode key to

select the desired direction – and then press to return to standby. (Please refer to MENU 27)

Press to memory channel, turn encoder knob clockwise or

anti-clockwise, or directly input through the keypad to select the specified

channel CH-20, and then press to confirm,, there is voice prompt “receiving memory” (it

prompts when the voice guide is ON). Finally press to return to standby. (Please refer to

MENU 30)

After above, the settings for memory channel to the repeater is done.

If necessary for the channel name editing, please press to switch the working

mode to channel mode. Select the specified channel CH-20, and then press

to change channel mode. Turn encode key to select name

and then press to confirm, finally press to return to standby.

problems as following chart, it the problems are still happening, please reset it to avoid some

mis-function operation, search assistance from the experienced technician or contact your buyer

accordingly.

problem solution

The transceiver can not be powered

on

·The battery may be exhausted, please change the

new battery or re-charge it

·The battery was not installed correctly, please

re-stall

The battery life is too short to use ·The battery life is over, please change a new

battery

·The battery is not full charge

The receiving light keeps flashing,

But there is no sound coming out

·make sure the volume is highest

·make sure the CTCSS/DCS settings are the same

as the transmitting transceiver

It seems the keypad does not work ·make sure if the keypad is locked or not

·make sure if the keys are not stuck

In standby, the transceiver will

transmit automatically even the PTT

key is not pressed

·make sure if VOX function is ON or not, and its

level is set too low or not

Some functions can not be stored

normally

·please confirm if the transceiver is working in

channel mode, since some functions are only set in

frequency mode via programming software

There are other disturbed signals or

noise (from other groups) in the

channel

·please change the CTCSS/DCS frequencies set in

your group.
