3. Earpiece Usage Guide

3.1. Safety and Usage Recommendations

Before using the wireless earpiece clean the ears well. Otherwise the audio filter will get filled with ear wax. It will decrease sound quality or may even damage the earpiece, which will be recognized a no warranty clause!
Apply a new battery every time you use the earpiece.
Make sure that you use only LR521 ALCALINE batteries. The batteries of SR type that contain silver particles can seriously damage the earpiece, which is not a warranty case.
Never put the transmitter too close to the earpiece, or earpiece contacts will be damaged.

3.2. Usage Steps

To make use of the wireless earpiece, insert the battery supplied in the set as shown in the picture below.

Then put the earpiece into your ear. Avoid pushing it too deep. You should feel comfortable while using the earpiece.
After using the earpiece pull it out with the help of a special ejection cord. Eject the battery and clean the earpiece carefully using a moist cotton swab.
