Charging the Battery Pack
New batteries or batteries that have been stored for a long time period should be fully charged before
placing into service. Low battery voltage will shorten the talk range and will make the performance of
radio worse.
When the battery pack requires charging then the radio will sound a high pitch tone every second
How to Charging
Plug the charger (CHZ-260FB) into the electricity power outlet for AC220V.
The charger (CHZ-260FB) has two slots.
When charging the radio with the battery installed, insert the radio into front slot of the charger
after power off.

RADIO OPERATIONS
Installation and Removal of Antenna
Put the antenna into the antenna connector of the radio and turn the antenna clockwise for installation of
antenna and in order to remove the antenna from Radio, turn the antenna counterclockwise.
☞
CAUTION`
When installation of the antenna, giving a strong pressure to the Radio or pulling the antenna from
Radio with a strong power can make damage on the antenna connector, which may cause the Radio
to have critical problem.
Power On/Off
Turn Power switch clockwise and as soon as power is supplied, a “beep” sound is heard and the model
name of the radio is displayed and the Radio enters into the previous latest state.
☞
CAUTION`
If turning power on by pressing a button on Radio, the Radio may enter into a special mode, in this
case, the transmitting and receiving of radio may not be possible. Don’t use the Radio for the other
purpose apart from the above.
Transmission
Press the PTT button on the left side of Radio for transmission. The DTMF or 5 Tone is transmitted
according to the setting of the radio. During this time voice communication will not be made and after
that the red LED is turned on and voice is transmitted. For voice communication in the best sound quality,
it is recommended to talk 5~10cm away from the radio.
☞
CAUTION`
If transmitting consecutively for more than a certain time when setting of BCLO function and TOT
function, the transmission can be forcibly interrupted for other users.
Receiving
The radio operates as a receiving standby mode except for the transmitting period. User can adjust the
volume by using the volume switch. The green LED is turn ON when the radio receives the RF signal and
can heard the transmitting voice. According to the setting of transmitting radio, can be heard the DTMF

tone or 5 Tone.
If frequency is same as current channel but sub-tone is not same as current setting than the green LED
blinks. In order to check if the current channel is in use, press the Monitor button (M) on the left side of
Radio. If pressing the Monitor button (M) for about 2 seconds, the monitor function is activated with a
“beep” sound. To release from the monitor function, press the monitor button shortly.
Changing Channels
Channel Switch is used for changing channels. Turn the Channel switch clockwise to increase the channel
number with beep sound or channel number announced voice. And Turn the Channel switch counter-
clockwise to decrease the channel number with beep sound or channel number announced voice. The
channel frequencies include sub-tone information are pre-programmed by PC program.
Adjusting Transmitting Power
The transmitting power can be selected to High-Power mode or Low-Power mode. The user can change
the transmitting power by pressing the button which is pre-assigned by PC program. By changing the
power to Low-power mode under a good communication condition, the user can extend the battery life.
SCAN Operating mode
SCAN function is executed with a “beep” sound when pressing the button which is pre-assigned by PC
program during the standby state. The radio will change the scan channel and check the RF signal at
regular interval. Repress this button shortly then SCAN function can be deactivated.
A scan channel list must be created before SCAN can be used. The radio will not go into SCAN mode
where no scan channels are programmed.
Normal Scan
Once SCAN is activated, the radio will perform a normal scan mode. When the scan channel list is NS1,
NS2 and NS3 on the normal scan mode, the radio proceeds to scan in the sequence of NS1, NS2, NS3,
NS1, NS2, NS3.... During the receiving mode user can move to the next channel by pressing the red
button. And delete current receiving channel temporarily from the scan channel list.
If getting out of SCAN Mode or turning on power again, the list deleted temporarily is returned back to
the original.

Maintenance Manual
19
Priority Scan
As soon as priority scan channel is detected, the radio will change priority scan mode. When the scan
channel list is NS1, NS2, NS3 and priority scan channel is PS, the radio proceeds to scan in the sequence
of PS, NS1, PS, NS2, PS, NS3, PS, NS1....
During receiving signal through common channel, the radio scans the priority channel periodically. And if
the radio detects the signal on the priority channel, it starts to receive the signal from the priority channel.
During the receiving mode user can move to the next channel by pressing the red button. The user can
delete current receiving channel temporarily from the scan list and at that time, user can move to the next
channel. But the radio receives the signal from priority channel then it will not be deleted.
Transmitting
Pressing the PTT button cause the radio to transmit on selected channel frequency and to stop the SCAN
mode. And the selected channel frequency can be established in PC programmer.
Home channel.
Last receiving channel
Current scan channel.
Emergency Call
If pressing the button which is pre-assigned by PC program, radio transmitting the emergency alert tone
or 5-Tone message in Sell-call mode. Also user can hear the emergency alert tone. If the radio is set up
in repeated mode, the radio is transmitting the emergency alert tone periodically. This function can be
performed when SCAN is activated.
Monitor
In order to open the squelch compulsorily, press the button which is pre-assigned by PC program. If
pressing the MON key for more than 2 seconds, the squelch is opened continuously with a “beep” sound.
If you want to get out of this mode, press the MON key shortly once again, or turn off and on the power.
