18 Cochlear Update | FM Solutions

Many factors impact the battery life of a sound processor including the use

of some accessories. It is important to note that ear-level FM receivers that

require the use of the Euro Accessory Adaptor are active devices (i.e. they

draw power from the CP810 Sound Processor, unlike other accessories

such as the personal audio cable, which is not an active device). Therefore

use of an ear-level FM receiver with the Euro Accessory Adaptor will reduce

battery life of the CP810 Sound Processor. This reduction can range from

10-40% of battery life, depending upon various MAP parameters and

whether an ear-level Dynamic FM receiver is used. Ear-level Dynamic FM

receivers use more power than traditional ear-level FM receivers.

If the anticipated battery life is not sufﬁcient to support FM usage (i.e.

to enable 8-10 hours of listening), a message will be provided when

programming with Custom Sound 3.2.

Recipients with high powered MAPs (the battery life estimate is <19

hours with the standard battery module using two Zinc Air batteries) may

experience issues with FM use. In this scenario, the FM device exceeds

the power capability of the two Zinc Air batteries and Custom Sound 3.2

will display the message suggesting that the clinician may need to lower

the MAP stimulation rate, reduce the maxima, widen the pulse width or

recommend use of the standard rechargeable battery module.

Please note that towards the end of battery life, plugging in a coupled

ear-level FM receiver and Euro Accessory Adaptor may cause the sound

processor to shut down with the standard battery module (using two Zinc

Air batteries). The solution is to use fresh batteries when using an ear-level

FM receiver.
