- If the battery power has been used up. Please replace a new cell.
- Does the battery plate make contact with the metal component? Keep the battery contact
pieces clean to prevent contact fault. Clean the contact points.

2. How can whistling (Acoustic feedback) noise be reduced?
- If whistling (feedback) in ear is occurring, turn off the power or reduce the volume. Try and
choose your preferred size ear cap (4 sizes provided) to fit snugly and seal your ear canal; use
a different sized ear cap for a more snug fit if necessary. Remove your hand from your ear, the
whistling will go away. When you ensure the ear cap is sealing your ear snugly, turn the
hearing aid on or increase the volume slightly.
