• Service your hearing amplifier at regular intervals. Make sure there are no foreign
objects in between the earplug and headphones, as this could impair the sound.
Battery Handling Safety Precautions
• Use only the size and type of batteries specified.
• Be sure to follow the correct polarity when installing the batteries. Reversed
batteries may cause damage to the device.
• Do not mix different types of batteries together (e.g. Alkaline and Carbon-zinc or
rechargeable batteries) or old batteries with fresh ones. Always replace batteries
as a simultaneous set.
• If the batteries in the device are depleted or the device will not be used for
a long period of time, remove the batteries to prevent damage or injury from
possible battery leakage.
• Do not try to recharge batteries not intended to be recharged; they can overheat
and rupture (follow battery manufacturer's directions.)
• Do not dispose of batteries in fire, batteries may explode or leak.
• Clean the battery contacts and also those of the device prior to battery
installation.
