When the batteries are depleted, Battery-Icon appear on the display, and the recorder shuts off. It is recommended to set the HOLD switch to the HOLD position before you replace batteries to maintain the current settings (Time/Date, etc.). For your convenience, the recorder also logs the current settings in nonvolatile memory at hourly intervals.

Power Supply
The HOLD switch functions as a power button. When you do not use the recorder, set the HOLD switch to the HOLD position while the recorder is stopped. This will power off the recorder and minimize the battery drain.
