NOTICE
Turn off the device before replacing the sensor module.
If not possible, insert a new sensor module 10 s after the old one is removed.
QSA2700D includes a built-in proximity sensor and enters into energy efficient
mode if no person is detected in front of the sensor (approximately 1 m) over the
past few minutes. In energy efficient mode, the screen is off and the sensor is
working and transmitting the signals at regular intervals. Otherwise, the screen is
activated and the sensor is in continuous working mode.
Keep the proximity sensor area clean as dirt may affect the detection performance.
