Operation steps
1. Rotate the power switch / volume control knob clockwise to conduct the power supply. Then adjust
the volume by rotating the knob. Rotate the knob counter-clockwise to power off.
2. Rotate the encoder knob to select the desired channel. Clockwise rotation can raise the channel
number while counter-clockwise rotation lowers the number. The encoder also can hear the
annoucement of the current channel number.

Function operation and instruction
> All the function operations are programmable via KG-998 programming software.
CTCSS & D.C.S
This transceiver is equiped with CTCSS (Continuous Tone Controlled Squelch System) and D.C.S
(Digital Controlled Squelch) functions. You can ignore the unwanted calling from the frequency via this
function. Only when receiving the same CTCSS tone or D.C.S code, the transceiver will release mute.
> CTCSS or D.C.S cannot make the dialogue concealed or encrypted, but only can prevent you from the
unwanted dialogue
SQL
When squelch function is on, and the signaling is compatible, there is audio output from speaker. The
higher level for squelch is programmed, there are more weak signals will be avoided. If you program the
lower level of squelch, radio will be easily interference with the noise or other useless signals.
Power Save Mode
When save function is ON, the transceiver automatically activates to voltage save mode 10 seconds
07
‘@wouxun
Professional FM Transceiver
after there is no signals or any operations. It cuts off the receiver circuit for a while in order to save
voltage, and it continues working when there is signal detected. The save mode is exit if there is any
signal or operation onto the transceiver.
Time-out Timer
Time-out timer is to prevent the transceiver from continuous transmitting for a long time. The transmitting
will be interrupted compulsorily when the continuous transmitting time is over than the preset value.
This function is to prevent the transceiver from being overheated and damaged.
Scan
This function is a receiving way for monitoring the wanted channel communication.
Press PF1 that is programmed as "Scan". The transceiver will scan one by one according to the channel
numbers on the scan list. When scanning, green light flashes. Indicator LED illuminates green when a
certain channel receives signals and the signaling types are matched.
While the scan function is activated, the transceiver will check the calling being available in the scan channel.
If there are signals, it will switch to the channel for receiving calling.
Scan Mode
TO: After searching signals, the transceiver will continue scanning if without any operation within 5
seconds, Press PTT key, the transceiver transmits the appointed channel by encoder. Scan will stop
after transmitting.
08

Function operation and instruction
CO: The transceiver will stop scanning when searching a signal. It will resume after 3 seconds when the signal disappears.
Press PTT key, the transceiver will transmit the appointed channel by encoder. It will stop scanning after transmitting.
SE: Scan will stop when receiving a signal. Press PTT key, the transceiver will transmit the searched channel.
It will be back to the appointed channel by encoder after transmitting if there is no operation in 10 seconds.
Scan Adding
Note: m Radio only scans the channels which is added to scan list.
m Method: Program it via software.
Busy channel lockout
This function is to prevent the interference of other communicating channels. If the selected channel
is occupied, press PTT, the transceiver can not transmit.
vox
When detecting voice, the transceiver will switch to transmitting mode automatically.
As VOX should detect voice, transmitting will be a little delayed, and the beginning of the voice may
not be transmitted.
There are 10 levels for VOX. Higher level, less sensitive.
VOX Delay Setting
When VOX transmits is started after tone is detected, but there is no any more new tones, there is delay
time programmable to keep transmission.

Voice Guide
It is supported to have English and Chinese as voice guide.
TX/RX Programmable
It is programmable to program any lawful frequencies for RX and TX within the specified frequency range.
SOS
This SOS function can be pre-programmed on the sidekey for quick operation when emergency. Then
the radio will send the SOS audio upon the channel through the encoder. The time for sending is 10
seconds every time, while interval is 5 minutes. During SOS time, it exit the SOS mode if carrier signal
comes in, press PTT to transmit or other operations on the radio.
Alarm Emergency
This Alarm function can be pre-programmed on the sidekey for quick operation when emergency. The
radio will send the ANI Code+Alarm Code out upon the channel through the encoder, meanwhile, the
speaker will be Alarm audio output for emergency. Press any buttons can exit from the Alarm Mode.
DTMF
Optional signal
It is programmable to set the DTMF transmission via the programming software in the Optional signal.
10

Function operation and instruction
Select DTMF is to set the DTMF encoding& decoding ON, while select OFF is to turn off the DTMF function.
Ð Please set this function in the CHANNEL MESSAGE by the programming software, which can be specially
programmed for each channel.
DTMF Transmit
It means the duration of transmitting DTMF, with the range from 50 milliseconds to 500 milliseconds.
DTMF Interval
It means the interval for the digital when transmitting DTMF, with the range from 50 milliseconds to 500
milliseconds.
All calls, Group calls and Selective calls
This series of transceiver is available for the ANI ID transmission, ANI ID editable and the DTMF decoding
functions. It is programmable to use the All calls, Group calls and Selective calls function during the group
communications without other equipments.
Please program the settings as followings:
1. Editing the ANI ID code
Every set of the communicating transceivers among the groups should be well programmed their codes
rr respectively.
Professional FM Transceiver
2. DTMF signaling to be ON
Every set of the communicating transceivers among the groups should be well programmed to open
the DTMF signaling.
Low voltage prompt
When the voltage is low, the transceiver will sound two "Toot", and the light will flash every 10 seconds
and a “Toot” sounds.
How to use the intelligent charger
1. Insert the AC plug into the outlet (AC: 90-240V), the charger indicator flashes once. That means the
charging is in standby.
2. Insert the battery into the charger, the RED indicator continuously flashes. That means the charging
is on the progress.
While the GREEN indicator continuously flashes. That means the charging is complete.
>> When inserting the exhausted batterypack, the intelligent charger will precharge the batterypack in trickle form.
The RED indicator will be flashing at the moment. This process is lasting for 10-20 minutes. And then the charging
is normal. Red indicator continuously flashes, And then the GREEN indicator flashes when the charging completes.
Ð Trickling charging the exhausted batterypack is in order to protect lithium-ion batterypack better.
