Safety Precautions

Exercise caution when handling rechargeable batteries (accumulators)

All lithium-ion battery packs (Li-ion), regardless of their indicated charge state, are capable

of producing electrical current sufficient to cause personal injury and/or property damage.

Do not dispose of lithium-ion battery packs (Li-ion) in a fire or with regular waste. Lithium-

ion battery packs (Li-ion) may explode if exposed to open flame. The battery packs are

hazardous waste and may contaminate ground water sources if disposed of in landfills.

IDEAL INDUSTRIES, LTD. tries to provide the maximum protection possible by installing an

automatic reset fuse in the battery packs, to help stop high current discharge as quickly as

possible. However, these fuses may not completely protect against a momentary arc

discharge, which can result if the battery pack's electrical contacts are shorted. The

following battery pack handling precautions must be closely followed to avoid risk of injury.

•

When a battery pack is not installed in the Display (DH) or Remote (RH) handset, it

should be kept in a clean, dry, non-conductive package.

•

Keep conductive materials away from the battery pack at all times.

•

Keep contact sides of the battery pack away from each other at all times.

•

Battery packs can be charged while in the Display (DH) and in the Remote (RH)

handset, but also externally with the adapter. Charging in any other manner may

cause the battery pack to explode.

•

Always install, remove, store, and charge the battery packs in a non-explosive

atmosphere.

•

Observe operating and storage temperatures (see chapter 1.3. Dimensions, Weights,

Operating Conditions).

•

Do not allow children or persons unfamiliar with the precautionary instructions in

this manual to handle or recharge the battery packs.

•

Do not open the battery pack case. There are no user-serviceable parts inside the

case, and the batteries in the case are not replaceable.
