* Determined by the memory density of the card;
i.e., greater card density means less battery time.
a. Insert a slender pointed object, such as the end of a paper clip, into the hole on the upper side of the card.
(See Fig. 4.)
b. Release the battery holder by pressing the paper clip against the catch and pulling the battery holder straight out
from the card. (The battery cavity is located at the top of the card. See Fig. 5.) When the battery holder is free
from the card the battery will fall out.
c. Replace the old battery with a fresh one. Be certain to match battery polarity to the + and – shown on the holder.
d. Place the new battery into the holder, squeeze the holder containing the new battery tightly, and reinsert it into
the battery cavity.
WARNING
Battery MUST be replaced within 30 minutes
