Frequently QA and solutions
Q:Why there are some background noise?
A:Hearing amplifiers are electronic devices, which have a quiet but occasionally noticeable sound. Sometimes, it can be a distracting noise.Actually, it is the electric current sound existing in all good machines.Generally, the higher the power, the greater the static sound.
S:Adjust to Noisy Mode when start wearing, then turn up the sound gradually. Generally, You will get used to it after 2-3 weeks.
Q:What causes the feedback?
A:If the ear dome is not inserted well into ear canal or air leaks at the ear dome edges, when the device is close to hand or wall, a certain amount of sound will go back into the microphone.The sound is re-amplified which causes that annoying whistle.
S:Try and select suitable ear dome. Put the ear dome into the ear canal and make sure it fits snugly inside.
