set for 10 minutes for Screensaver from the factory.
IR detector: Enables the infrared technology on recorder is an innovative idea to prolong
the lifetime of LCD display. The Infrared detector works with the Screensaver to protect the
LCD. The Infrared detector senses the movement of body temperature when a user gets
closer or walks away. (Range approximately 2 meters). Operation is as follows: Set the IR
Sensor to On and Screensaver at 1 Min. Display will turnoff in 1 minute after the user walks
away from the recorder. Once the Infrared detector senses heat movement within 2m of the
recorder, display turns on straight away, without needing to press any key on the recorder.
Note:
IR( Infrared ) detector needs to work together with Screensaver, it cannot function alone.
However, the Screensaver can function alone after the IR Sensor is disabled.
