1.2 DESCRIPTION
The KNG is a handheld FM transceiver designed for use in domestic and foreign Land Mobile services.
The radio supports standard analog FM and digital C4FM modulation pursuant to TIA-102.BAAD (Project
25 Common Air Interface Description for Conventional Channels) et al. The radio can be congured for
as many as 5000 channels that can be arranged into channel zones. Each channel species unique
receive and transmit RF frequencies, sub-audible squelch, digital control parameters, etc.
Top panel controls include on/o󰀨/volume, channel rotary selector, a concentric two-position switch, an
orange momentary switch, and two toggle switches with dealer programmable function. The side panel
contains a PTT switch, and two programmable push buttons. Connectors are provided via the side
connector for external antenna, speaker, microphone, programming, and options. Some models include
a front panel LCD display for status information, four programmable push buttons, and a keypad for
tailoring radio operation.

OPERATION AND PROGRAMMING
2.1 GENERAL INFORMATION
This section contains information concerning the installation and programming of the BK Radio KNG
APCO Project 25 digital radios.
UNPACKING AND INSPECTING EQUIPMENT
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for evidence
of damage incurred during shipment. If a claim for damage is to be made, save the shipping container
to substantiate the claim. The claim should be promptly led with the transportation company. It would
be advisable to retain the container and packaging material after all equipment has been removed in the
event that equipment storage or reshipment should become necessary.
BATTERY INSTALLATION
Installing the Battery
1. Turn the radio o󰀨.
2. Align the tabs on the bottom of the battery with the slots on the radio.
3. Push the top of the battery toward the radio until release tab “clicks”
into place.
Removing the Battery
+TS ON
-
Release Tab
1. Slide the release tab toward the bottom of the radio.
2. Pull the top of the battery out.
(Approximately 30o)
3. Pull up to remove the battery pack.
NOTE: All information programmed into the radio is maintained even when the battery pack is removed.
BK Radio battery packs are available in a variety of capacities and types for special applications.
Rechargeable battery packs can be charged separately or while attached to a radio.
Periodically check the contacts on the battery pack for dirt that could prevent a good electrical contact
with the charging base.

Page 2-2 Service Manual - KNG Portables
Operation and Programming
ANTENNA INSTALLATION
NOTE: Transmitting without an antenna could result in damage to your radio.
Use BK Radio approved antennas only. Use of non-qualied or mismatched antennas could result in
diminished radio operation. Published radio specications cannot be guaranteed with non-approved
antennas. Bent, broken or damaged antennas should be replaced.
INSTALLING THE ANTENNA
Insert the radio’s antenna connector into the threaded connector of the
antenna and turn it clockwise until it is rmly seated.
REMOVING THE ANTENNA
Holding the base, turn the antenna counterclockwise until released.
2.2 BASIC RADIO OPERATION
Turn power on by turning the Volume knob clockwise. A beep sounds, indicating the radio is operational.
The LCD display shows the programmed display information of the currently selected channel.

Microphone
PTT
1. Press the PTT (Push-To-Talk) switch. When the radio is transmitting the
indicator LED glows red and TXD or TXA appears in the display.
2. Talk in a normal voice with the microphone one to two inches from your
mouth.
3. Release the PTT switch to stop transmitting.
If the length of your message is nearing the programmed Time-Out Timer
setting, a tone sounds indicating 5 seconds left to transmit. At the end of the
programmed time, the transmitter automatically shuts o󰀨 and an alert tone
sounds. To continue transmission, release the PTT switch, then press it again
and continue talking.
If the Transmit Indicator does not glow and a tone sounds, you are on a receive-
only channel or the channel is busy (see Busy Channel Lockout). Select an
authorized transmit channel.
NOTE: When using a channel programmed for mixed mode transmit the signal will be transmitted in the
mode selected by the TX Digital selection. Or if programmed for Mixed Mode Talkback, the radio will
transmit in the mode of the last received channel while the “RX” icon is displayed. (See Mixed Mode
Operation.)
