Transmitting and Receiving
To use your KP3X 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 KP3X 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 KP3X Communicator is equipped with an automatic squelch system that automatically cuts off weak transmissions
and unwanted noise due to terrain conditions and range limitations.
The Automatic Power Save Feature
Your KP3X Communicator has a unique circuit designed to dramatically extend battery life. If it senses no transmission
within 5 seconds, it automatically switches to the power save mode. The Communicator can still receive transmissions in
this mode.
The Display Backlit Display Feature
Your unit’s LCD Backlight display automatically lights up for 5 seconds with the press of any key.
