periods (weeks, months) between uses. Without battery backup for the real time clock, clock functions will
cease if battery input power is removed.
The backup battery has a life expectancy of approximately five years depending on conditions. After this
time, you should contact Basler Electric to order a new battery, Basler Electric P/N 38526.
Replacement of the backup battery for the real-time clock should be performed
only by qualified personnel.
Do not short-circuit the battery, reverse battery polarity, or attempt to recharge
the battery. Observe polarity markings next to the battery socket when
inserting a new battery. The battery polarity must be correct in order to provide
backup for the real-time clock.
It is recommended that the battery be removed if the DECS-150 is to be
operated in a salt-fog environment. Salt-fog is known to be conductive and
may short-circuit the battery.
Failure to replace the battery with Basler Electric P/N 38526 may void the
warranty.
The time must be reset after replacing the battery. Time settings such as
12/24 hour format are not affected.
Battery Replacement Procedure
The battery access is located on the back of the DECS-150. See the Terminals and Connectors section

Step 2: Locate the battery socket on the back of the DECS-150. Remove the old battery. Consult your
local ordinance for proper battery disposal.
Step 3: Insert the new battery so that the polarity markings on the battery match the polarity markings
on the battery socket.
Step 4: Return the DECS-150 to service.
