Signia AX Care & Maintenance

Signia Hearing Aid
Cleaning Guide

Step-by-step daily and weekly maintenance for your Signia Pure Charge&Go AX. A 10-minute daily routine prevents 85% of avoidable repairs — and keeps your AX performing like new.

Under 10 Min Daily Prevents 85% of Repairs 4 Daily Steps 4 Weekly Tasks
Section 1

Know Your Device Parts

Identify each part before you start cleaning. Each area requires a different cleaning method and carries a different risk level.

🎙️

Microphone Ports

Tiny holes on the top spine that capture sound for the AX processor. Debris here causes muffled audio and reduces directionality.

🔘

Rocker Switch

The button on the back for adjusting volume and switching listening programs. Keep free of debris to ensure reliable function.

Charging Contacts

Gold points on the bottom curve. Must stay clean for the contact charging system to work reliably overnight.

👂

Click Dome / Receiver

The thin wire and rubber tip that sits in your ear canal. The wax guard filter is housed inside this tip — the most failure-prone component.

Why This Matters for the AX Platform: The AX uses dual-processor architecture with dedicated sensors for directionality. Even partial blockage of a microphone port can degrade the separation between the primary and support processor — reducing the signature AX sound experience you paid for.

Section 2

Step-by-Step Daily Routine

Perform these 4 steps every morning before inserting your hearing aids. The entire routine takes under 10 minutes.

1

Wipe the Housing

Why this matters

Oils from your skin and hair degrade the plastic casing over time and seep into internal seams — causing corrosion that voids the manufacturer warranty.

  • Hold the hearing aid by the main body — never by the receiver wire.
  • Use a soft, dry, lint-free cloth or dry tissue only.
  • Wipe the entire outer surface with gentle, sweeping strokes.
Never use alcohol wipes, water, or chemical sprays. They strip the AX nano-coating and void your warranty.
2

Brush the Microphone Ports

Why this matters

Clogged microphone ports directly impair the AX processor's ability to separate environments — causing muffled sound and reduced directionality, especially on the 7 AX model.

  • Locate the tiny holes on the top spine of the device.
  • Turn the hearing aid upside down so holes face the floor.
  • Brush downward with the small cleaning brush — gravity pulls debris out.
Never push bristles into the ports — only sweep across the surface.
3

Check the Ear Piece (Dome)

Why this matters

The dome sits in earwax all day. Wax buildup on or inside the wax guard filter is the #1 cause of completely silent hearing aids — and the most preventable.

  • Inspect the rubber dome tip — is there visible yellow or brown wax?
  • Wipe the rubber dome firmly with a clean tissue or cloth.
  • Check the small white wax guard filter — if it contains dark wax, replace it immediately.
  • Replace the rubber dome completely every 4–6 weeks regardless of appearance.
4

Clean the Charging Contacts

Why this matters

The Pure Charge&Go relies entirely on metal contact charging. Even a thin layer of oil or dust creates electrical resistance — causing incomplete charges or overnight charging failures.

  • Locate the gold metal points on the bottom curve of the hearing aid.
  • Wipe firmly with your dry lint-free cloth.
Pro Tip: Also wipe inside the charger case wells — dust accumulates there and blocks the connection from the case side.

Best Time to Clean: Clean your hearing aids first thing each morning, before insertion. Night cleaning is a close second — removing the day's accumulation before it dries and hardens. Never clean immediately after removing from the ear, as the devices may still be warm and slightly humid.

Section 3

Why Precision Maintenance Matters

Service repair data shows exactly which steps have the highest return — and what happens when you skip them.

Common Failure Points — Charge&Go Models

Based on service repair data
Receiver / Wax Guard
60%
Charging Contacts
25%
Microphone Ports
10%
Other
5%
60% of all failures originate at the Receiver and Wax Guard (Step 3). Another 25% are caused by dirty Charging Contacts (Step 4). Together, Steps 3 and 4 alone prevent 85% of avoidable repairs.

Impact of Dirty Contacts on Charging Time

Hours required to reach 100% charge
Clean contacts
4 hrs
Slightly dirty
6 hrs
Very dirty / oily
8+ hrs
Dirty or oily contacts can more than double charging time from the standard 4 hours to 8+ hours — or prevent a full charge entirely, leaving you with a dead device by mid-afternoon.
Section 4

When to Change the Wax Guard

The wax guard is the smallest part of your hearing aid — and the one most likely to cause a complete failure. Here's exactly when and how to replace it.

Replace Immediately If:

Sound is noticeably weak, thin, or completely silent — despite the device being powered on.
You can see dark or brown wax lodged inside the small white filter ring at the center of the dome.
It has been more than 4 weeks since the last replacement, even if the device seems to be working fine.

How to Change It:

Use the double-ended wax guard tool included with your device.
The black end removes the old, clogged filter — insert and pull out.
The white end inserts the fresh new filter into place.
Always consult your audiologist if you are unsure of the process — we're available remotely across all 50 states.

Weekly Maintenance Checklist

In addition to your daily routine, these four tasks keep your Signia AX performing like new long-term.

🔄 Change Domes

Rubber degrades, changes color, and traps earwax that cannot be fully removed by wiping alone. Replace every 4–6 weeks.

⚡ Clean Charger Wells

Dust accumulates inside the charging case and blocks the metal contacts from both sides of the connection. Wipe case wells weekly.

🔧 Vent Cleaning

Pass the thin wire tool through the mold vent to clear blockages that cause occlusion — the hollow or echoing sensation when speaking.

💧 Dehumidifier Treatment

Place aids in a UV drying jar or desiccant box overnight for deep moisture removal — especially important in humid climates.

Humid Climate? Moisture is Your #1 Enemy: Patients in humid regions should use a dehumidifier nightly (not just weekly) and consider upgrading to IP68-rated devices. Ask your audiologist about moisture-resistant options from the Signia AX lineup. Our licensed specialists serve all 50 states via telehealth — no in-office visit required.
