LECTROSONICS, INC.

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

receiver and searching for clear frequency channels.

(See Menu Selections from Main window and Frequen-

cy Scan Mode.)

Pilot Tone Indicator

A steady “P” icon will be displayed when a pilot tone from the transmitter is present, in those com-

patibility modes which use pilot tone: 200 Series, Digital Hybrid (400 Series), IFB and Mode 6.

The icon will blink if no pilot tone is present from the transmitter, and it 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

disables the squelch, so the receiver will produce loud noise when no matching transmitter signal is

being received, regardless of which compatibility mode is selected.

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 from 1uV to 1000uV on the bezel to the left of the LCD display.

Audio Level

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

transmitter 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 SEL Down together for one second.
