WARNING !!
Servicing of batteries should always be performed or supervised by
someone who has read and understood the following precautions and who
understands the hazards associated with storage batteries. This procedure
should not be performed by someone who is unauthorized or who is
incapable of following these precautions.
OBSERVE THE FOLLOWING CAUTIONS
Only the battery assembly in this unit is user serviceable. The battery compartment is
accessed by removing the front panel as described in the following instructions. No
other user serviceable parts are contained in this UPM. Do not remove any cover
other than the front battery access panels.
A battery (even a depleted one) can deliver very high currents when short-circuited.
There is a danger of electrical shock. Remove all watches, rings, bracelets or other
metal objects. Use only tools with insulated handles.
Do not dispose of batteries in a fire. There is a danger of explosion. Do not dispose of
batteries in an environmentally unfriendly manner. Batteries may be returned to ETA
Systems for proper disposal.
Do not open or mutilate the batteries. This may release electrolyte that is toxic to the
environment and harmful to the skin and eyes.
Replacement batteries may be ordered from ETA Systems by phone or via our website
at www.ETA Systems.com. If purchasing batteries from another source, be sure to use
the type and quantity of batteries described in the table in Section 10.

Please note: Changing the batteries in this UPM is designed to be a safe and simple
procedure. Batteries may be replaced while the UPM is on and providing power to the

to your connected system and components.
