My Approach Z80 or Z82 Won't turn on from Sleep Mode
When the Approach® Z80 or Z82 range finder is on it will utilize a lower power mode or sleep mode in between usage to conserve battery life. The sleep mode will deactivate the viewfinder and appear to be off until you hold the device up to your face and active the sensor in the thumb groove. If the device should get stuck in sleep mode, please update the software using the FAQ below.
