1. Daily maintenance
It is important to keep your devices clean and dry. On a daily
basis, wipe them clean using a soft cloth or tissue.
V. MAINTENANCE AND CLEANING
All data in this manual, such as service time, charging time,
continuous working time, and charging times are derived from
our internal laboratory testing and meant for reference purpos-
es only. Your exact usage and times may differ depending on
various conditions and use patterns. It is a normal phenome-
non to hear some high-pitched whistling or buzzing when the
hearing aid is at a high volume level and not fitted well into the
ear as a result of mic feedback. If this occurs, lower the volume
and adjust the hearing aid within the ear. Also check to make
sure you are wearing the best size ear domes to ensure a
proper fit in the ear canal, as this may also induce some minor
feedback if not snug in the ear.
To avoid potential damage from excess humidity or
perspiration, the use of a drying kit is also recommended.
2. Care and maintenance
When not in use, store in a secure area away from small
children and pets.
Do not place hearing aids or charging case near high-tem-
perature areas such as stoves or direct sunlight.
Do not leave the devices in a humid place for a long time,
such as bathroom.
Take care not to poke the microphone holes with any sharp
objects to avoid damage.
Do not disassemble or attempt any repairs by yourself. Doing
so will void your warranty.
