Choosing a Channel
Your KP4X COMMUNICATOR has 14 channels you can use to talk to others. To choose a channel:
1. To enter or exit to COMMUNICA TOR mode, press the
Power
key for about 3 seconds. A long keybeep tone is locally
generated (after a short keybeep tone) when the unit goes into COMMUNICATOR Mode and the LCD will display the
segments and icons for the COMMUNICATOR.
2. Press the
Menu
for at least one second. The Channel number on the LCD display will flash.
2. Press the
Up
or
Down
key to reach higher or lower channel. Auto-repeat is engaged by pressing and holding either the
Up or Down key. You’ll hear a standard key beep with each channel change.
3. To exit the Menu, press PTT/Call key.
Channel Scan
To scan the whole 14 channels of the COMMUNICATOR for any activity
1. Press the
Scan
key found on the side of the unit. Once engaged, the unit will start to rapidly scan the whole 14
channels of the COMMUNICATOR for any activity. The unit will pause on an active channel for 4~5 seconds before
resuming Scan function.
2. To exit the Scan mode, depress the
Scan
key
Transmitting and Receiving
To use your KP4X COMMUNICATOR to communicate with others:
1. The unit is continuously in RECEIVE mode when the unit is ON. Turn on COMMUNICATOR mode by pressing the
Power key for 3 seconds.
2. Press and hold the
PTT
key and speak as you normally would, holding the microphone about 2~3 inches away from
your mouth. While transmitting, the TX icon appears on the display. To avoid cutting off the first part of your
transmission, do not speak immediately after pressing the
PTT/Call
key; first pause briefly, then speak.
2. When you are finished speaking, release the
PTT/Call
key. You are now ready to receive incoming transmission. While
receiving transmission, the
RX
icon appears on the display.
For optimum performance, make sure the ANTENNA is pointing upright.
Sending a Call Alert Tone
To send a Call Alert Tone, press the
PTT
key twice in rapid action. The Call Alert Tone will be automatically transmitted
for a fixed length of time. During transmission, the
Call
icon will appear on the display and a Call Alert Tone is also locally
generated for confirmation of operation. The COMMUNICATOR will return to standby mode following completion of the
Call Tone sequence. For optimum performance, make sure the ANTENNA is pointing upright.
Voice Operated Transmission (VOX)
Your KP4X COMMUNICATOR is equipped with a user selectable
Voice Operated Transmitter (VOX)
that can be used
for automatic voice transmission. In this convenient mode, transmission is automatically initiated by speaking into the
microphone. There is no need to push the
PTT/Call
key.
To adjust VOX level:
1. Enter to
Menu
mode. Advance through the Menu until the
VOX
icon appears on the display.
2. Press the
Up
or
Down
key to toggle between On and Off function of the VOX. When VOX feature is on, the VOX icon
will appear on the LCD display.
3. To exit the Menu, press PTT/Call key.
To get the full advantage of the convenience of a hands free transmission and the privacy of conversation, you
can purchase an Ear Bud with Microphone (see Accessory Order Form) to be used in conjunction with the VOX
feature of your COMMUNICATOR.
To use the Ear Bud:
1. Set your COMMUNICATOR to VOX Mode.
2. Lift the Headset / Charger Jack Cover located at the side of your unit.
3. Insert the Ear Bud Jack into the Headset Jack. Wear the Ear Bud and adjust the Microphone location.
The Auto Squelch Feature
Your KP4X COMMUNICATOR is equipped with an automatic squelch system that automatically cuts off weak
transmissions and unwanted noise due to terrain conditions and range limitations.
