Protect Your Investment
Whether you own the Pure Charge&Go 3, 5, or 7 AX, your device uses advanced "Augmented Xperience" technology. Wax and moisture can block these sensors. Consistent cleaning ensures the Signia AX sound processing works perfectly.
Know Your Device Parts
Identify these areas before cleaning.
Microphone Ports
Tiny holes on the top spine. They pick up sound.
Rocker Switch
The button on the back for volume/programs.
Charging Contacts
Gold points on the bottom. Must be clean to charge.
Click Dome / Receiver
The wire and rubber tip that goes into your ear.
Step-by-Step Daily Routine
Perform these 4 steps every morning.
Wipe the Housing
Why: Oils from your hair and sweat can damage the plastic and seep into seams.
- Hold the hearing aid by the main body.
- Use a soft, dry, lint-free cloth or tissue.
- Gently wipe the entire surface.
- WARNING: Do NOT use alcohol wipes, water, or cleaning sprays. Chemicals can damage the AX coating.
Brush the Microphones
Why: Clogged mics cause "muffled" sound or reduced directionality (a key feature of the 7 AX).
- Locate the tiny holes on the top spine of the device.
- Turn the hearing aid upside down (so holes face the floor).
- Brush downwards using the small brush tool. Gravity helps debris fall out.
- Do not push bristles into the holes; just sweep across the surface.
Check the Ear Piece (Dome)
Why: This part sits in earwax all day. It is the #1 cause of "dead" hearing aids.
- Inspect the rubber dome tip. Is there visible yellow/brown wax?
- Wipe the rubber dome firmly with a tissue or cloth.
- If the wax is inside the little white filter (Wax Guard) in the center, it must be changed.
- Note: Domes should be replaced completely every 4-6 weeks.
Clean Charging Contacts
Why: The Pure Charge&Go relies on contact charging. Dirt creates resistance and charging failure.
- Locate the gold metal points on the bottom curve of the hearing aid.
- Wipe them firmly with your dry cloth.
- Pro Tip: Also check inside your charger case wells. Dust collects there too!
Why Precision Matters
Common Failure Points (Charge&Go Models)
Based on service repair data
Insight: 60% of issues are the Receiver/Wax Guard (Step 3), and 25% are Charging issues (Step 4).
Impact of Dirty Contacts on Charging
Charging time to reach 100%
Insight: Dirty contacts can double your charging time or prevent a full charge entirely.
When to change the Wax Guard?
The "Wax Guard" is a tiny white filter under the rubber dome. It is the gatekeeper of sound.
Change it immediately if:
- ⚠ The volume is weak or completely silent.
- ⚠ You can see dark wax inside the white filter ring.
- ⚠ It has been more than 4 weeks since the last change.
Weekly Maintenance Checklist
