If DTMF and ANI are both enabled, the ANI tone sequence is transmitted
only after the LAA0290 microphone’s
[ENT]
key is pressed while the
PTT
switch is activated. You will hear a sidetone.
TIME-OUT TIMER
The transmit Time-Out Timer limits the duration of calls and guards
against accidentally locking on the transmitter and tying up the radio
system. Your dealer can program the duration of the Time-Out Timer
(15-225 seconds, or disabled).
BUSY CHANNEL
If the radio has been programmed for Busy Channel operation, it will
operate in one of the following three Modes:
• Busy Channel Indication
• Busy Channel Lockout
• Busy Channel Lockout with Override
BUSY CHANNEL INDICATION
The yellow Busy Channel Indicator glows if there is carrier activity on the
selected channel. If the selected channel is a Channel Guard channel
and the proper Channel Guard value is not detected, the Busy Channel
Indicator remains on for the duration of the carrier activity and no
message is heard. During Scan and Priority Scan operation, the Busy
Channel Indicator glows when activity is detected on any channel on the
Scan List.
When scanning or priority scanning Channel Guard channels with
the
[CG]
(Channel Guard Disable) button OFF and activity has been
detected, the Busy Channel Indicator glows for the time period necessary
to determine if the proper Channel Guard value has been received. This
will cause the Busy Channel Indicator to flash at various rates.
BUSY CHANNEL LOCkOUT
The Busy Channel Lockout feature applies only to those channels
programmed with a receive Channel Guard value. When carrier activity is
detected on the channel selected, the radio checks the receive Channel
Guard value. If the proper Channel Guard value is present, the radio can
transmit on that channel even if the
[CG]
button is off.
