Precautions for Handling

(4) By their nature, LCD displays react more slowly at low temperatures, and may appear

dark at high temperatures. The display will return to normal at room temperature.

Lithium Backup Battery

attention at once.

(2) Do not use metal instruments such as pliers to hold the battery, or you could cause a short


(3) Do not disassemble or heat the battery, or you could rupture it.

CF Card

(1) The CF card is a precision device. Do not drop CF cards or expose them to vibrations.

Doing so could lose the images recorded on them.

(2) Do not store or use CF cards near objects that generate magnetic fields, such as TVs,

speakers, or magnets, or in locations affected by static electricity. Doing so could lose the
images recorded on the CF card.

(3) Do not place CF cards in direct sunlight or close to heating appliances. Doing so can

distort the cards and make them unusable.

(4) Do not spill liquids onto CF cards.
(5) Always store your CF cards in a case or cabinet to protect the data stored on them.

back images.

(8) Do not store CF cards in hot, dusty, or humid locations, or in locations exposed to static

electricity or magnetic fields.
