Walgreens WGNBPW-520 Manual page 15

Replace the batteries if:
1. The weak battery symbol appears in the display.
2. Nothing appears in 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 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.
