Changing the Batteries

These steps will show you how to replace disposable batteries for SONNET.

Check that the battery pack cover is in the unlocked position. If it’s not, use the screwdriver provided in your SONNET kit to turn the lock counter-clockwise to the unlocked position.

Be careful not to use too much force when you turn the battery pack cover lock.

Use the magnetised underside of the DL-Coil to remove the used batteries from the battery pack frame. Place the coil over each battery one at a time to remove each from the frame.

Sonnet-Battery-Insert
4

Insert the zinc-air batteries with positive (+) poles facing out. Before you insert the new battery set, make sure the battery contacts are clean and dry. Avoid touching the battery contacts inside the battery pack frame. Finally, remove the foil stickers covering the batteries. Always replace all of the batteries at once rather than mixing used and new batteries.

Sonnet-BatteryPack-Close

Slide the battery pack cover up fully over the battery pack frame. The battery pack cover lock should be facing to the front.

Battery Options

Use only type 675 batteries or SONNET rechargeable batteries. For type 675, we recommend using zinc-air batteries that are designed especially for hearing implant systems. However, you cannot use zinc-air batteries when using SONNET with the WaterWear accessory
