MILEMARKER, MM-01
BATTERY REPLACEMENT PROCEDURE
Milemarker Raceclock model MM01, utilizes two internal sealed lead-acid batteries for clock operation. With
fresh, fully charged batteries installed, the clock will operate for approximately 10 hours. These batteries, EN part
number 860-008, are 6V and are connected internally in series to provide 12V operating voltage. Battery kit,
MM01-BK provides the correct replacement batteries and the necessary replacement parts which are removed
during battery replacement.
To replace the batteries, it is necessary to partially disassemble the clock.
1)
Using a Philips screwdriver, remove the 12 screws around the base of the clock.
2)
Insert the screwdriver into the lower vent-slots on the ends of the clock and gently pry upward, pushing the
base downward to separate the top enclosure from the base. Alternately pry each end until the top enclosure
is completely free from the base.
