Ericsson AEGIS M-PA, Operator'S Manual

Page: 13 / 40

CARRIER CONTROL TIMER
This feature, programmable on a per channel
basis, prevents unnecessary channel traffic and ra-
dio damage in the event of a "stuck" mic. If the
programmed timer times-out during a transmission
the radio will sound an alert tone and disable the
transmission. The beeping tone will continue until the
PTT BUTTON is released. Releasing the PTT BUT-
TON resets the timer.
CHANNEL BUSY
If the radio is receiving a signal when the PTT
BUTTON is pressed, an alert tone will warn the
operator that the radio is receiving a carrier and the
transmission will not occur. "RX BUSY" is displayed
and the alarm is sounded as long as the PTT BUT-
TON is pressed. This feature is programmable on or
off on a per channel basis.
RECEIVE ONLY CHANNEL
If the selected channel is programmed as receive
only the radio will sound an alert tone if a transmis-
sion is attempted. "RX ONLY" is displayed.
RADIO/CHANNEL FAILURE
If the synthesizer is unable to lock correctly on
the selected channel, or another radio failure occurs,
an alert tone will sound. If incorrect programming is
detected or the synthesizer fails to lock, the display
flashes "NO LOCK" then the selected channel’s
name.
PRIVATE MODE DISABLED (Scan and System
Models)
If the selected channel is programmed for private
operation and private transmit mode has been dis-
abled using the PVT button, the radio will sound a
low-pitched beep when the PTT button is pressed.
This warns the operator that the radio is transmitting
clear (non-encrypted) audio.
OPERATION
POWER-UP
After the battery pack and antenna have been
installed, turn the radio on by sliding the ON/OFF
SWITCH on the battery pack up. After the radio has
completed a power-up self-test, it will begin operation
