HoMedics Deluxe Wrist Manuel D'instructions page 14

Replace the batteries if:
• The weak battery symbol appears on the display.
• Nothing appears on the display when the power is
switched on.
As the supplied batteries are for test only, they may be
discharged earlier than batteries you buy in stores. Replace
all batteries at one time (as simultaneous set). Use only
1.5V AAA LR03 alkaline batteries. Remove batteries
when unit is not in use for extended periods of time. Date
and time will need to be reset if batteries are removed
or replaced. Clean contacts on battery and in battery
compartment with a soft dry cloth each time you install
batteries.
Note:
Batteries are hazardous waste. Do not dispose of them
together with the household garbage.
