Replacing the Batteries in the Patriot
This PAT describes how to replace the batteries in Patriot SPS 850 units. Replacing the batteries
should take about 30 minutes.
Batteries should be replaced by a qualified technician. If you have any questions or problems,
please call BEST's Technical Support Center at 800-356-5737. (Outside of the U.S. and
Canada, call your local BEST office.)
To replace the batteries, you will need the following:
! Needle Nose Pliers
! Black Electrical Tape
! Phillips Screwdriver - 6" long below handle*
*Note: The screwdriver should be six inches long below the handle so you can replace the
inside screws easily. Using a magnetic screwdriver makes removing and replacing the
screws easier.
Before you go on to Section 1, read the important safety warnings on the next page.
