3. 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. To avoid potential damage from excess humidity or perspiration, the use of a drying kit is also recommended.

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 purposes only. Your exact usage and times may differ depending on various conditions and use patterns. It is a normal phenomenon 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.

TIPS FOR BETTER COMMUNICATION

It will take practice, time, and patience for your brain to adapt to the new sounds that your hearing aids provide. Hearing is only part of how we share thoughts, ideas and feelings. Reading lips, facial expressions, and gestures can help the learning process and add to what amplification alone may miss.

Please review the following simple communication tips:

For You

• Move closer to and look at the speaker
• Sit face-to-face in a quiet room if possible
• Try out different locations to find the optimal places to listen
• Minimize distractions
• Background noises may be frustrating at first; remember, you have not heard them for a while
• Let others know what you need; keep in mind that people cannot “see” your hearing loss
• Develop realistic expectations of what your hearing aids can and cannot do
• Better hearing with hearing aids is a learned skill combining desire, practice, and patience. You will learn and adjust, it just takes a little time. Remember to be patient with yourself. For Your Family and Friends Your family and friends are also affected by your hearing loss. Request that they:
• Get your full attention before beginning to speak
• Look at you or sit face-to-face
• Speak clearly and at a normal rate and level; shouting can actually make understanding more difficult
• Rephrase rather than repeat the same words; different words may be easier to understand
• Minimize distractions while speaking
