ALL OPERATIONAL DIFFICULTIES:
If this timer does not function properly for any reason, please replace battery with a new high quality battery (see
“Battery Replacement” section). Low battery power can occasionally cause any number of “apparent” operational
difficulties. Replacing battery with a new fresh battery will solve most difficulties.
BATTERY REPLACEMENT:
An incorrect display, no display or operational difficulties indicate the battery should be replaced. Use a coin to
open battery cover on back of timer (turn cover approximately 1/8 turn counter-clockwise). Equivalent battery
replace- ments are: RAYOVAC RW42, DURACELL D357,
and EVEREADY 357. Insert battery with positive side facing you. Replace battery cover.
