Lectrosonics UCR211 - Manual (Page 6)

UCR211
also has protection circuits that prevent damage to the
receiver if a positive ground power source is applied.
LCD DISPLAY
The display has four main windows. Pressing the MENU
button rotates through each of these windows.
If the battery gets low on either transmitter or receiver, a
message will interrupt the display every few seconds and
flash a “LOW BATTERY” warning.
After power is turned off and back on again, the unit
defaults to the main window and to the most recent
frequency, audio level, transmitter battery type and
locked/unlocked status settings. These settings are
retained even if the batteries are removed.
POWER UP SEQUENCE
The power-up sequence consists of four messages that
appear automatically over a period of a few seconds
after the power is switched on.
1) LOCKED or UNLOCKED status
2) The name LECTROSONICS
3) The model number and firmware revision
4) The frequency block of operation
After these introductory messages are displayed, the
main window will appear.
The UCR211 is fully operational during the power up
sequence and will immediately respond to button pushes
made before the automatic sequence is completed. If a
valid transmitter signal is already present when the
receiver is turned on, the audio output will typically be
engaged somewhere in the middle of the power-up
sequence, following a brief delay to allow the audio
circuits to stabilize.
(See LOCKING AND UNLOCKING THE UCR211
FRONT PANEL CONTROLS.)
POWER OFF
When the power switch is moved to the OFF position the
audio output is instantly muted (squelched) and the
message “POWERING OFF...” is displayed briefly before
switching off.
