Inserting the Battery
To insert the battery, pull the tab on the battery
door outward until the door swings all the way
open (see figure 1). Remove the paper tab
from the back of a proper size battery. Place
the battery into the battery door (see figure 2).
Observe the correct polarity. The “+” sign on
the battery must match the “+” sign stamped
on the battery door.
Gently close the battery door. Avoid forcing
the battery door shut. If the door doesn’t
close, check to see the correct size battery was
inserted and that the “+” signs are aligned.
If your instrument’s battery door does not have
a “+” sign, insert the proper size battery and
gently close the battery door. If it doesn’t close
easily, remove the battery, turn it over and
reinsert it. The battery door should now close
easily.
