Operating Instructions - Battery
The Pro 3600 is powered by a 9-volt battery. A new alkaline battery will provide 500 hours of
use. A 9-volt lithium battery can be used for even longer life.
To extend battery life, the Pro 3600 shuts off automatically when left undisturbed for five
minutes (to reactivate, push the ON/OFF button) unless there is activity on the serial port.
Note: Hooking serial port pin 5 (REQ) to pin 9 (BATT+) disables the auto-power shutoff..
The Pro 3600 also indicates when the battery is low. Change the battery when the display
alternately flashes "LO bAt" with angle measurements. (NOTE: The Pro 3600 does not
display inaccurate angles due to a weak battery.)
To install/replace the battery
•Unscrew the battery compartment cover screw.
•Remove the cover.
•Install or replace the battery.
•Replace the cover and tighten the screw.
