CAUTION: Operation of the transmitter without a proper antenna installed may
result in permanent damage to the radio.
NOTE: The radio’s LED will glow red continuously when you have the PTT button
pressed and the radio is transmitting
Receive
When you have finished transmitting, release the PTT button to receive. You are now in
receive mode. When another operator transmits on the correct frequency the speaker will
become active.
Scanning
This feature will support a number of different scanning modes. These are Dealer
programmable.
Normal Scan
Any number of channels shall be entered into the scan list. The LED shall flash green if
programmed to. The flashing green LED will stop when ‘CARRIER’, or ‘CARRIER AND
CORRECT TONE’ is detected. During scan delay, the LED shall remain clear. When
Scan Delay expires and Scan Speed resumes, the LED shall also resume flashing green.
Priority Scan
A priority channel can be programmed at the initial radio set-up stage. The priority
channel will be part of the list of channels that make up the scan list. The priority
channel when used with other scanned channels will operate as follows:
P1 → S1 → P1 → S2 → P1 → S3 → P1 → S4 → P1, etc.
Priority Look Back
One channel can be programmed by the dealer to be the Priority channel, which will
enable ‘Look-back’. Pressing the Scan button shall activate Priority Look-back. The
Priority Look-back causes the radio to periodically ‘Look-back’ to the priority channel for
the presence of a carrier regardless of the channel that the user may be on.
Scan Channel Delete
Pressing the ‘Monitor’ key, (when in scan mode and stopped on the channel) shall
temporarily delete the channel from the scan list. When power is restored or the scan list
channel position is selected again, the originally programmed scan list shall be activated.
