Important things to know about the ETY•COM™ Headset:

For best results, it is essential that the earphone and the microphone are placed in the optimal position.

• Eartip selection is critical to success with the headset. The ETY•COM comes with an assortment of eartips; select an eartip that allows the earphone to seal the ear canal. Moisten the eartip if necessary to ease insertion. The eartip should stay in position so the boom does not rotate downward during use.
  
• The ETY•COM microphone is highly directional. It picks up your voice within a narrow range and rejects background noise coming from outside that range. To stay in this range, the boom should be bent so that the microphone is within 1/2 inch of your mouth; otherwise the microphone will reject your voice.

If the headset volume decreases or the sound quality declines, change the filter.

• The ETY•COM has a special filter that smoothes the frequency response and prevents earwax from entering the earphone. The filter is located at the end of the headset and is visible when the eartip is removed. A dirty filter will reduce or block the headset output. The need to change filters varies widely among users.

1. Remove eartip		2. Remove filter with tool		3. Insert new filter provided

4. Gently press into place		5. Attach eartip
