1) Wipe

• Remove aids. Wipe shell, microphone ports, and earpiece with a dry cloth.
• Use the small brush to lightly sweep microphone openings.

2) Check

• Inspect dome/tube or earmold. If wax is visible at the tip, clean or replace the guard.
• Confirm left/right labels before storing.

3) Dry

• Place in a drying jar or electronic dryer overnight (best in humid climates).

4) Charge or store

• Rechargeables: seat fully in the charger; confirm lights.
• Disposable batteries: open battery doors overnight to air-dry if not using a dryer.

• Avoid showers or swimming with aids. Remove before hair spray or powder.
• Use a sweatband/retainer for exercise or hot weather.
• If wet: power off, remove battery (if disposable), dry exterior, and place in dryer (no heat gun).

When to change

• Sound is softer or dead on one side.
• Wax seen in the guard or dome tip.
• Every 4–8 weeks as routine, sooner if waxy ears.

How to change a guard (typical system)

• Remove dome gently to expose the guard.
• Use the new guard stick: pull old guard out, flip stick, press new guard in, discard stick.
• Re-fit dome firmly (match size). Tug lightly to ensure it’s secure.

If unsure of your system (CeruShield, HF3, etc.), check your brand’s leaflet or clinic video.

• Dome sits flush; no sharp edges or soreness after 2–3 hours.
• For earmolds: no rubbing or whistling when you cup your hand lightly over the ear.
• Persistent soreness → contact clinic for refit or different dome size.

• Keep your phone’s Bluetooth on and the brand app updated.
• If calls sound choppy: toggle Bluetooth off/on, then open the app; or reboot phone.
• For TV streamers: power cycle the streamer, then reconnect in the app.

Rechargeables

• Seat fully; green/solid light means charging. Keep charger on a surge-protected outlet.
• For power cuts: use a small power bank if your charger supports USB.

Disposable zinc-air

• Remove tab and wait 1–2 minutes before inserting to activate.
• Store cool and dry; never in bathroom. Recycle used batteries safely.

• Brush microphone ports and receiver tip thoroughly.
• Change wax guard if buildup noted.
• Wash earmolds/tubes with mild soapy water (if your model allows); dry completely before use.

• Pack a travel pouch: charger or spare batteries, domes, guards, brush, dryer sachet.
• Use a power bank if your charger supports USB; carry a plug adaptor.
• Airport security: keep aids on; show staff the charger if asked.
