Operation DMH Series VHF Radio
BK RADIO Page 3-13
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.
3.11.1.1 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).
3.11.2 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.
3.11.3 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.
3.11.4 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.
3.11.5 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.
