MAIN WINDOW
Pilot tone indicator - A steady “P” icon will be displayed when a pilot tone from the transmitter is present.
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.
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 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 approximately one hour of operating time is remaining. The icon above the Tx symbol works in the
same manner to indicate the transmitter battery condition. The Tx battery icon usually appears 5 to 10
seconds after the transmitter signal is acquired. When external power is being used, the Rx battery icon
changes to look like a power plug.
LOCKING AND UNLOCKING THE UCR411
The panel controls can be “LOCKED” to prevent accidental changes being made during operation and handling.
To LOCK the UCR411 - Hold the MENU button down until a bar tracks horizontally across the screen and the word
“LOCKED” appears. If the MENU button is released before the word “LOCKED” appears, the unit will remain UN­
LOCKED. When in a LOCKED state, the pilot tone bypass toggle is also defeated.
In LOCKED state, the use of the MENU and UP/DOWN buttons is limited to “view only” and attempts to change
selections will result in a screen displaying the word “LOCKED.” The unit cannot be used for RF scanning when it is
set in the LOCKED state.
To UNLOCK - Hold the MENU button down until a bar tracks horizontally across the screen and the word “UN­
LOCKED” appears. When the unit is UNLOCKED, all settings can be altered.
The UCR411 can be LOCKED or UNLOCKED from any of the main four windows. It cannot be switched when it is in
the scanning mode or from other subordinate screens.
