UHF Digital Hybrid Wireless ®
Rio Rancho, NM 15
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.
Pressing the SEL/SEL button accesses the SEL selec-
tions for setting up the receiver and searching for clear
frequency channels.
Pilot Tone Indicator
A steady “P” icon will be displayed when a pilot tone from the transmitter is present. The “P” will
appear only in those compatibility modes which use pilot tone, such as the native 400 Series, 200
Series modes and 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 or enable the pilot tone on Receiver 1, hold SEL and
press the UP button briefly. To bypass or enable the pilot tone on Receiver 2, hold SEL and press the
DOWN button briefly. Bypassing the pilot tone also disables the squelch, regardless of which compat-
ibility mode has been selected.
Antenna Phase Indicator
This icon antenna is displayed when the SWITCHING DIVERSITY mode is selected. 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.
Audio Levels
One icon is used in the SWITCHED DIVERSITY mode and the other when RATIO DIVERSITY is
selected. The 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.
Battery Levels
When the COMPAT mode is set for a compatibility mode that supports battery telemetry (400 and
200 Series), a battery icon is displayed on the LCD to indicate the transmitter battery condition. The
receiver will periodically check the battery voltage and update the icon in a “fuel guage” manner. In
the example at left, the icon indicates about “half full.” When other COMPAT modes are selected, this
area of the LCD will be blank.
If selected in the TXBAT setup screen, a transmitter battery timer is available for any compatibility
mode. It accumulates hours and minutes whenever the transmitter is turned on, and retains the ac-
cumulated time even when the receiver is off. The icon represents a digital clock readout (rotated 90
degrees) and in this example is indicating 4 minutes. To reset the battery timer, change the selec-
tion in TXBAT to something other than a timer mode (NOT AAT or 9VT).
Icon Description
NOTE: When the RATIO DIVERSITY mode
is selected, both receivers are combined to
pick up the same transmitter, so the Main
Window will display a single audio channel.
