WARNING

Do not immerse the RPS II in water, and do not use liquids to clean any part of the product.

1. Disconnect the battery from the power supply unit and the device. Remove all cables.
2. Wipe the exterior of the battery with a clean cloth.

Storing

CAUTION

Batteries must be charged to 100% indicated by four green LEDs and switched off before storing. You must recharge the batteries to 100% again after six months of storage. When not in use, all Lithium-Ion batteries self-discharge over time. If not periodically recharged (ie, every six months), the RPS II will eventually self-discharge to the point that it can no longer be recharged. If this occurs the RPS II is no longer usable and is unrecoverable.
Store the RPS II in a cool, dry place.

Note: A fully charged battery when left switched on, self-discharges to 0% of full capacity within four weeks of storage. When switched off, the battery self-discharges to 0% of full capacity within six months of storage.

Servicing

The RPS II is intended to provide safe and reliable operation when used and maintained in accordance with the instructions provided by ResMed. There is no servicing necessary during the lifetime of the battery.
The service life of the RPS II exceeds 500 recharge cycles. After 500 recharge cycles, the battery will last about 60% of the time from its original condition. A full charge in an older battery will not last as long as in a new battery. ResMed recommends that the RPS II be tested for battery duration regularly. As with all electrical equipment, if any irregularity becomes apparent, you should exercise caution and contact an authorized ResMed service representative.

Traveling

Consult with your carrier if you intend to take the battery on board with your device.
