For first-time users
It is difficult to hear what is being said when you first put on a
sound collector. Please continue to use the device every day To
the extent that you do not get tired. Gradually get used to the
device by increasing the duration of use in the following four
stages.
1. Listen to your own voice in a quiet place.
2. Talk with your family or friends in a quiet place.
3. Listen to the TV (news channels) at the same volume as the
people around you.
Try not to turn up the volume too high at the beginning, as it
may cause fatigue until you get used to it. Your family members
should also warmly support you until you become proficient in
using a sound collector. The cooperation and thoughtfulness of
your family and others around you will be most encouraging. If
you cannot hear well, if the beeping does not stop, or if you are
bothered by the beeping sound when wearing the device
1. If the earpiece is not inserted correctly into the ear canal, a
beeping sound (howling) may occur. In this case, please adjust
the position and direction of the sound collector.
2. Replace the earpiece with one that fits your ear canal.
3. It takes about one month to get used to the sound after
starting to wear the sound collector, although it varies from
person to person.
