operation and Programming
emergency alarm (emergency alert)
Press and hold the button to initiate an Emergency Alarm mode.
Once Emergency Alarm is initiated, the emergency message is transmitted automatically. The radio will
emit a series of beeps and “EMERGENCY” will flash on the display. “EMERGENCY” and the incoming
P25 ID or MDC number or label will be displayed on the receiving radio. An alert tone will be emitted if
the radio is programmed to do so.
note:
When the emergency alarm is broadcast for digital operation, the radio will not receive the
signal while a scan is active (Priority, Channel, Zone) unless the following conditions are met: 1) the
Data Mode for the Emergency Channel of the TX Radio (radio declaring the emergency) needs to be
Repeated or Direct (not FNE); and 2) the Data Scan Hold Time on RX radios needs to be non-zero.
Analog channels will work while scanning without any special settings on either radio.

Conventional Digital Channels
The KNG may optionally be configured for Secure communication on channels operating in Analog or
Digital Mode. To determine if your radio is encryption compatible, remove the battery and check the
Options Label near the top of the radio. “KZA0577” indicates the encryption option is installed.
required setup
Radios that have the DES/AES factory option for encryption must have encryption keys loaded with
an APCO Project 25 compatible key fill device such as the Motorola KVL 3000 Plus, using a BK Radio
keyloader cable. The radio can hold up to 64 AES and/or DES keys.
After loading keys in the radio, the PC Radio Editor must be used to configure the radio’s key table and
to assign default transmit keys to each channel.
Radios that have the OTAR factory option support Over-the-Air Rekeying of encryption keys (OTAR).
The PC Radio Editor must be used to enable OTAR and to mark the channel(s) that will communicate
with the Key Management Facility (KMF). In addition, the radio must have key encryption keys (used
only to encrypt other keys) loaded with an APCO Project 25 compatible key fill device such as the
Motorola KVL 3000 Plus, using a BK Radio keyloader cable.
Basic operation
The receiver automatically detects both clear and secure signals.
The transmitter selects clear or secure operation based on each channel’s programming. Digital
channels can be programmed to always transmit encrypted, always transmit clear, or to select the
encryption mode with the TX Secure switch.
The display indicates Secure Operation as follows:
In Standby Mode, if the radio will transmit in Secure Mode when PTT is pressed,
the encrypt icon is displayed.
When receiving an encrypted signal, the encrypt icon ‘’ flashes in the display.
When transmitting an encrypted signal, the LED alternates between red and blue.
transmit [seC]
Channels programmed for selectable encryption can have “Transmit Secure” programmed as a
switch, button or menu item. The default setting uses the collar switch to select Transmit Secure.
Ø = encrypted, O = clear
When SEC is on, encrypted channels programmed for switchable encryption will transmit an
encrypted signal.
NOTE: The SEC switch has no effect on channels programmed as Encrypted Only or Clear Only.
Channels in the Ready-to-Transmit Encrypted mode will display the symbol on the top line of the
LCD.
