If you hear a slight whistling sound when wearing the hearing amplifier,
check that your earplug is fitted properly in your ear. If it is not snug
enough, use a different earplug.
7. Maintenance and cleaning
IMPORTANT
• Remove the batteries from the device before cleaning.
• Clean the hearing amplifier and the earplugs with a clean, dry cloth after
each use. If they are very dirty, you can also moisten the cloth with a mild
soapy solution. Never use abrasive, corrosive or solvent-based cleaning
products.
• Allow the hearing amplifier to dry fully after cleaning. Store the hearing am-
plifier in a safe, dry and clean place.
• Under no circumstances should you hold the hearing amplifier under wa-
ter, as this can cause liquid to enter and damage the hearing amplifier.
• If you do not intend to use the hearing amplifier for longer periods, remove
the battery from the device to prevent possible leaking.
