REPLACEMENT PARTS

TROUBLESHOOTING
- I can’t hear anything through my Acoustic Tube Earphone!
You can determine whether or not the Acoustic Tube Earphone is the source of the problem by testing whether you can hear incoming radio calls through the speaker transducer with the earphone disconnected. Remove the Acoustic Tube from the clothing clip assembly by rotating the twist connector. Put your ear near the clothing clip assembly while your radio is receiving an incoming transmission. Inspect the Acoustic Tube for damage or dirt and debris and then either clean or replace the tube as needed. If you cannot hear received signals through the speaker transducer with the earphone removed, you should contact PRYME technical support for further assistance. - The volume on my Acoustic Tube Earphone used to be very loud?
The most likely cause is a blockage inside the Acoustic Tube or a hole or kink in the tube. Over time the Acoustic Tube can become blocked with condensation, dirt, earwax, or body sweat.If the Acoustic Tube appears damaged, replace it with a new one. If the tube appears to be blocked or dirty, clean the tube using the procedure on page 4. - My Earphone is becoming discolored!
The Acoustic Tube used to be clear but it is now turning brown (or yellow). What can I do? The tube may simply be dirty. You can try cleaning it using the procedure on page 4. - My Acoustic Tube appears to have a “air bubble” in it or the tube material is distorted. Can I fix it?
If the Acoustic Tube appears to have an air bubble inside of the tube, it may just have moisture or condensation trapped inside. Follow the cleaning instructions on page 4 of this guide.
