Some KNG radios are equipped with optional P25 Trunking capability. To determine if your radio
is trunking compatible, remove the battery and check the Options Label near the top of the radio.
“KZA0579” indicates the trunking option is installed.
Trunking parameters and functions can only be programmed by qualified persons via PC. Contact
your system administrator or radio dealer for information on how your radio is programmed.

If the radio is powered on when a trunking channel is selected, the radio will attempt to register with
the selected trunking system.
The LED will flash twice upon successfully registering with the system and setting talkgroup
affiliation.
If the affiliation was unsuccessful the LED will continue to flash.
If the radio is not in range of the system “Out of Range” will be displayed and an alert tone will sound
every ten seconds.
If registration is refused or denied, a denied message and tone will appear briefly before switching
to “Out of Range” mode.
After successful registration the programmed LCD display criteria is displayed.

When the PTT is pressed, a three beep Talk Permit Tone will be heard if the channel is available.

sCan oPtions
Channel scan [sCan]
Conventional Channels
When on, Channel Scan monitors activity on the scan list channels in the currently operating zone.
Scan operates only while the radio is not transmitting.
Channels designated as scan channels are identified by the

symbol at the top of the LCD display.
If allowed, the scan list can be edited by the radio user. (See Channel Scan List).
When Channel Scan is on, the
C symbol will be shown at the top of the LCD display.
When a signal is detected, scanning stops and the message is received. The received channel is
shown in place of the selected channel.
Once the signal ends, the radio continues to monitor the channel for the preset scan delay time
before it resumes scanning.
Channel Scan operation can be a switch or as a button or menu list item.
Channel Scan may be used in conjunction with Priority Scan operation (see Priority Scan).
