Warning: Sound processors and related accessories contain small

parts that alone or in combination may pose a hazard of

inhalation, choking or ingestion. Swallowing or inhaling small

parts can cause severe or fatal injuries. Use the tamper-resistant

locks to keep small parts attached to the processing unit where

available, including parts that t between the processing unit and

battery module. Always supervise children under 3 years of age

and others who may be at risk of inhalation, choking or ingestion

of small parts when they use the sound processor and related

accessories. When not in use, keep small parts, and combinations

of small parts, out of reach from children. If small parts are

swallowed or inhaled, seek immediate medical attention.

Battery life

Batteries should be replaced as needed just as you would with

any other electronic device. Battery life varies according to the

programs used each day, your implant type, the thickness of

skin covering your implant, and the size and type of battery.

A completely empty rechargeable battery will typically take up

to four hours to fully recharge.

To maintain good condition of your rechargeable battery and

extend its lifespan, it is important to know how to charge,

maintain and store your battery:

ꞏCharge battery before storing. The optimum storage

environment is a cool, dry place.

ꞏDo not discharge battery completely before recharging.

ꞏIt is not recommended to store the battery for extended

periods of time without using or charging. If you have

more than one battery, rotate the batteries through

usage.

ꞏAvoid exposure to temperature extremes and humidity

in storage and use, such as direct sunlight or inside a

parked vehicle.

The amount of charge a battery holds naturally diminishes over

time. When a battery reaches its lifespan and can no longer be

charged suciently, the charger will indicate the need for

battery replacement by a ashing orange LED indicator.

To help gain the longest life from your battery, your clinician can

set your sound processor to turn o two minutes after you take

it o your implant.
