Main Window (LCD)
The Main Window displays information concerning the
condition of the Pilot Tone, antenna phase, RF and
audio signal levels and battery conditions for both the
receiver and the associated transmitter. It is also the
access portal to menu selections for setting up the re-
ceiver and searching for clear frequency channels. (See
Menu Selections from Main Window and Frequency
Scan Mode.)
Pilot Tone Indicator
A steady “P” icon will be displayed when a pilot tone from the transmitter is present. The “P” will ap-
pear only in those compatibility modes which use pilot tone: 200 Series and the native 400 Series
modes, plus Mode 6. The icon will flash if no pilot tone is detected and will change to a small “b” if the
pilot tone has been bypassed. To bypass the pilot tone, hold MENU and press the UP button. Hold
MENU and press UP again to restore normal pilot tone squelch. Bypassing the pilot tone also dis-
ables the squelch, so the “pilot tone bypass” function has an effect even in those compatibility modes
that do not use pilot tone.
Antenna Phase Indicator
This icon shows antenna phase switching activity. As the antenna phase is switched, the symbol will
flip vertically.
RF Level
This icon changes in size vertically to indicate the strength of the incoming RF signal. RF levels are
engraved on a scale from 1uV to 1000uV on the bezel to the left of the LCD display.
Audio Levels
This icon changes in size horizontally to indicate the audio level (modulation) of the signal received
from the transmitter. The icon display will change to a solid rectangular block when the audio signal is
being limited in the transmitter. Levels in dB are engraved into the bezel above the LCD display.
Battery Levels
The icon above the Rx symbol indicates the receiver battery condition and will flash when approxi-
mately one hour of operating time is remaining. When external power is being used, the Rx battery
icon changes to look like a power plug. The area above the Tx symbol features either a transmitter
battery status icon or the transmitter battery timer, depending on the TXBAT setting. The transmitter
battery status icon is available only in compatibility modes supporting battery telemetry (400 and 200
Series). In such cases, the transmitter battery status icon appears 5 to 10 seconds after the transmit-
ter signal is acquired. If selected in the TXBAT setup screen, the transmitter battery timer is available
in any compatibility mode. It accumulates hours and minutes that the communications link is active,
retaining the timing even when the receiver is off.
Note: To reset the battery timer, press and hold MENU and SELECT Down together for one second.
