20 BK Radio
PA Public Address
Press the [PA] button to turn the Public
Address system on or off. When PA is on,
pressing the microphone PTT switch causes
audio to be routed to the audio amplifier
without enabling the transmitter.
ACC Accessory
Press the [ACC] button to turn the installed
accessory on or off. Up to three ACC buttons
may be installed for different accessories.
SCAN OPERATION
RECEIVE
Scan operates only while the radio is not transmitting.
The radio checks for signals on channels in the preset
scan list, as well as the channel selected by the
Channel Selector knob.
When a signal is detected, scanning stops and the
message is received. The received channel is shown
in place of the transmit channel.
Once the signal ends, the radio continues to monitor
the channel for the preset scan delay time before it
resumes scanning.
BASIC SCAN
1. Press the SCN button to enable Scan (an arrow
will appear above the button).
2. If Priority Scan is enabled, press the PRI button to
turn it off.
The display indicates Scan operation by flashing the
SCN annunciator (alphanumeric mode) or by two
flashing bars (numeric mode).
SCAN CHANNEL GUARD CHANNELS
1. Press the SCN button to enable Scan (an arrow
will appear above the button).

2. If the CG button has an arrow over it, press the CG
button once to turn Channel Guard Disable off.
When a signal is detected, scanning stops while the
radio checks for the proper Channel Guard value. If the
signal contains the proper Channel Guard value, the
radio receives the message. Otherwise, the radio
resumes scanning immediately.
NUISANCE CHANNEL DELETE
With Channel Scan on and Nuisance Channel Delete
enabled, pressing and holding the [SCN] button for
more than 1 second will temporarily remove a currently
active channel from the Scan List. If the radio is
equipped with a keypad microphone, pressing the
[CLR] key while Scan is on will accomplish the same
thing. Not all microphones support these functions.
Contact your dealer to determine which features are
available with your microphone and have been
enabled in the radio. When the radio is powered off
and back on, the pre-programmed Scan List will be
restored.
TRANSMIT WITH SCAN ON
When operating in Scan mode, the radio transmits on
the channel selected by the Channel Selector knob.
1. Select a transmit channel by turning the Channel
Selector knob.
2. Press and hold the PTT switch and talk in a normal
voice. When the PTT switch is released, the radio
continues to monitor the selected channel for the
preset scan delay time before it resumes scanning.
TALKBACK SCAN
If your radio is programmed for Talkback Scan, press
PTT while a channel is active or while scan delay time
remains. You will be responding on the transmit
frequency of the received channel.
Talkback Scan will not work if Priority Scan is also on
and your radio is programmed to always transmit on
the Priority 1 channel.
