6. Instruções de operação
Seleção de 6.1 modos
The device features a three-position switch for selecting the operating mode:
- SINAL: In this mode, the device emits a short chime sound when motion is detected. This is suitable for use as a passage detector in shops or offices.
- OFF: The device is turned off and will not detect motion or emit any sound.
- ALARME: In this mode, the device emits a loud alarm sound (approximately 70dB) when motion is detected. This is suitable for security purposes.
