DCR822

LECTROSONICS, INC.

6

OLED Display

The display has four primary windows.  Pressing the 

Front Panel MENU button steps through each of these 

windows.
After power is turned off and back on again, the unit 

defaults to the Main window and to the most recent fre-

quencies, audio level, transmitter battery condition, and 

other user settings. These settings are retained even if 

the batteries are removed. The display illumination can 

be set to time out in 5 seconds, 30 seconds, or never.

Recorder Function

The DCR822 has a built in recording function for use 

in situations where the absolute minimum equipment is 

necessary, or as a backup to the main recorder system. 
The recorder samples at 48kHz rate with a 24 bit 

sample depth. The micro SDHC card also offers easy 

firmware update capabilities without the need for a USB 

cable or driver issues. 

Clock Function

The DCR822 has a built-in calendar and clock that are 

saved with power down. If the batteries are removed from 

the unit, the DCR822 “remembers” where it left off and 

resumes time and date counts from that point.

Power Off

When the Front Panel Power/Back button is pressed 

for several seconds, the audio output is instantly muted 

(squelched) and the message “POWERING OFF...” is 

displayed briefly before the receiver switches off.
