18 User Guide for the Neptune™ Sound Processor
Understanding Audible Alarms
Audible alarms are a programmable feature that can be used independently or in
conjunction with the Neptune LEDs to provide important information about system
status and battery life.
Table 2: Neptune Audible Alarms
Note: If the Neptune processor is placed within a retention device (e.g., pouch) or
worn beneath clothing, the processor audible alarms may be dampened and more
difficult for caregivers to detect.
Using AAA Batteries
The sound processor is powered by a single, off-the-shelf alkaline or lithium
disposable or nickel-metal hydride (NiMH) rechargeable AAA battery so you never
have to worry about power when traveling away from home or in an emergency. The
Neptune Battery Cover creates an airtight seal for swimming and bathing as well as
to prevent easy removal by young children.
Do not remove or replace the AAA battery while under water.
