Basics

Open the case by pulling up on the latch at front. Be sure to close it again securely before using it in a wet environment. You should here an audible click when it snaps shut.

To power on, slide the on/off switch at the lower left to the on position. The screen will light up and show the pressure range of the unit. After radio and sensor checks are complete, it will switch to pressure display mode and the fire hydrant blue led will begin flashing. It flashes each time pressure is transmitted.

To charge, open the lid and use the red usb charge cord supplied.  The regular usb plug-in can go to any powered usb outlet. The other end is magnetic and when placed near the charge connector will attach itself and start charging.
