Frequently Asked Questions - Nitro Custom SIEMENS

How do I change the battery in my Siemens Nitro Custom hearing aid?

Open the battery door using your fingernail. Remove the old battery and insert a new one with the positive (+) side facing up. Close the door. Dispose of used batteries properly.

How long does the battery last?

With typical use (16 hours/day), a size 10 battery lasts about 5-7 days, and a size 312 lasts about 7-10 days. Actual life depends on amplification needs and streaming.

Why is my hearing aid whistling or producing feedback?

Feedback often occurs when the hearing aid is not seated properly in the ear, when the volume is too high, or when using earwax buildup. Remove and reinsert, reduce volume, or clean the device.

Can I wear my hearing aid in the shower or while swimming?

No, the Nitro Custom is not waterproof. Remove it before bathing, swimming, or in high humidity. Use a dehumidifier overnight to remove moisture.

How do I clean my hearing aid?

Wipe the shell with a soft, dry cloth daily. Use a small brush to clean the microphone opening and sound outlet. Replace wax filters when clogged.

What do the different programs do?

Your hearing aid has multiple listening programs. Press the button to cycle through: Quiet for calm environments, Noise for crowded spaces, Music for enhanced sound quality, etc. Consult your audiologist for customization.

Can I connect my hearing aid to a smartphone?

Direct Bluetooth is not built-in, but an optional streaming accessory (like a miniTek) can connect to your phone and stream audio directly to the hearing aid.

Why is there no sound coming from my hearing aid?

Check if the battery is inserted correctly and not dead. Ensure the battery door is fully closed. Clean the sound outlet and replace filter if blocked. If still not working, contact your hearing care professional.

How do I use the telecoil?

Switch to the telecoil program (usually via button press). This allows you to pick up sound from loop systems in theaters, churches, or phones with a telecoil-compatible earpiece.

What should I do if the hearing aid gets wet?

Remove the battery immediately and dry the device with a soft cloth. Place it in a drying container or dehumidifier overnight. Do not use heat or microwave. If damage persists, take to a professional.
