2.phone calls
You can answer the phone using the Echo series ear-back hearing aid, but you need more
skills and practice to use it better. Since the microphone (sound input port) of the back
hearing aid is not directly opposite the ear canal above the auricle, the receiver should be
close to the top of the auricle when answering the phone.
When using the phone, if there is a feedback howling, please speak the phone receiver a
little away from the hearing aid.
The steps to clean earplugs are as follows:
◆Please separate the earplug from the guide tube of the hearing aid before cleaning the
earplug
◆If there are left and right earplugs, please pay attention to distinguish;
◆Use small brushes and soft dry cloth to clean earwax on earplugs. If necessary, but use
soft cleaning agents such as water, flexible soap wipe;
◆You can wash earplugs with water. Note: do not use water or other liquids to clean the
hearing aid fuselage;
◆ Please make sure the water on the tube and earplug has been blown dry before
reconnecting the earplug with the hearing aid;
◆ The connection between earplugs and hearing aids should correspond to the left and
right ears.
