TROUBLESHOOTING
1. No sound from hearing aid. Check as follows:
- If the battery power has been used up, please recharge it.
- If the earphone is damaged, please replace it with a new earphone.
- If the ear cap is blocked with wax or debris, or broken. Please clean it or replace a new ear
cap.
2. How can whistling (Acoustic feedback) noise be reduced?
- If there is whistling (feedback) in your ear, turn off the power or reduce the volume. Try and
choose your preferred sized ear cap (4 sizes provided) to fit snugly and seal your ear canal,
use another sized ear cap for more snug fit if necessary.
Remove your hand from your ear and the whistling will go away. When you have ensured that
the ear cap seals your ear snugly, turn on or increase the volume slightly until it is the proper
volume.
