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.

6.2 Proximity sensor (QSA2700D)

QSA2700D includes a built-in proximity sensor and enters into energy efficient

mode if no obstacle 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.
