PL Sleep Period (ms)
AGC
Clear Channel Definition
Transmit LED
This field specifies the "sleep period" for a radio on a PL channel when
the Battery Saver feature is active. During the sleep period, the radio
will power down the receiver and synthesizer and cease to check for
activity. After the sleep period, the radio will turn back on and will
remain in the ON state for a period of time sufficient to detect carrier.
If an on-channel carrier is detected, the receiver will be maintained in
the ON state for a period of time sufficient to detect PL.
If no valid PL is detected, the radio will return to sleep mode
immediately. If a valid PL is detected, the radio will unmute until the
channel unmuting conditions are no longer met. When carrier
disappears, the 10-second inactivity timer will be started. When this
timer expires, the radio will resume battery-saving activity by
periodically entering the sleep mode for the specified period. The sleep
period can be adjusted from five to 1050 ms in five-ms increments.
Note: As you increase the sleep period, battery life will increase,
but the possibility of missing the beginning of a call or
transmission will also increase.
The default is 60 ms.
AGC is available only on all JT1000 models, all VISAR models, and HT
1000 "B" and later models. Use the UP/DOWN arrow keys to enable/
disable the radio microphone AGC circuitry. Automatic Gain Control
or AGC has the ability to level out the variations in audio volume due
to a radio user speaking too softly, too loudly, or holding the radio too
far from his mouth. All messages will be heard at the receiving end at
a more pleasant volume level than if AGC were not used.
The default is Disabled.
This field is used to define the condition for a clear channel before PTT
or RAT transmission is permitted along with the Transmit Inhibit on
Busy Channel feature in the CHANNEL CONFIGURATION
screen (F4/F4).
Matched PL Clear channel is defined as an absence of carrier or a
carrier with a matched PL. The user will be inhibited from
transmitting if activity is detected on the channel with a
PL code other than his/her own, or with no PL.
No Carrier Clear channel is defined as an absence of carrier only. The
user will be inhibited from transmitting if any activity is
detected on the channel.
The default is Matched PL.
Use the UP/DOWN arrow keys to enable/disable this feature. If this
feature is enabled, the red LED will light up whenever the radio is in
the transmit mode.
The default is Enabled.
