Charge battery
Charge battery first
As long as the device is not yet installed outdoors, it should be charged with the included USB adapter. This keeps the battery fresh and prevents damage from deep discharge.
Push the plug from SOL_EXT4 cable into the socket of the M12SOL adapter. Then connect the plug of the USB Adapter with the other end.
Connect USB Adapter with an USB port of your PC or (better) a USB hub.
