What is the power supply source for the detector?
The detector with 2x LR6 / USB power supply is fitted with battery holders and a USB micro power supply connector. The detector can be powered only by batteries or through a USB connector, or it can be fitted with batteries and power from the USB connector. In this case, when the power supply from the USB connector is interrupted, the detector automatically switches to battery power.
You can use an ordinary adapter for 110/230VAC with USB micro connector as power supply, if the current carrying capacity exceeds 300mA, or you can use a power source with a USB 2.0 connector and a cable fitted with a USB connector on one end, and USB micro connector on the other. In this case the current carrying capacity of the source must exceed 300mA.
