BG122143361 Neither of the two microphones (soft and hard) included in the box has a switch. The only led that stays on while the Intercom operates, is the blue led that flashes rather slowly. The only way to turn off the blue led is to shut down the Intercom by the on-off switch I suppose.

BG122143361 There are two ways to pair, 1) Press simultaneously the Multi-function and the Power on-off buttons of both Intercoms and hold for about 4 seconds until the Leds flash red and blue, then you release the buttons and short press the button that has BT imprinted on it, of either one Intercom and they will pair. 2) Press and hold the BT button on both Intercoms until the Leds flash red and blue, release the BT buttons and then short press the BT button again, of either one Intercom and they will pair. To pair a Phone or GPS you follow the first method (1), and when the Leds start flashing red and blue you search for HYSNOX in the Bluetooth devices that are recognized by your Phone, GPS etc , select HYSNOX in your Phone and click on Pair.

BG122143361 One Intercom in each box. You have to buy a second one for your passenger. I received 2 boxes, each box containing one Hysnox HY-02 Intercom.
