What happens if I can’t hear out of my earpiece?
Most likely, the surveillance kit is not defective. There may be moisture in the acoustic tube causing the transmission to not be heard or heard at a lower volume than before. We suggest cleaning out the removable acoustic tube and trying again. We have a great guide on how to clean your acoustic tube here.
What is the warranty period for surveillance kits?
Warranty for Waveband surveillance kits is 1 year from the date of purchase. This covers any manufacturing defects and workmanship. These defects can include the push to talk button being stuck and earpiece not transmitting or receiving. This warranty does not cover physical damage or abuse.
How long should I wait to replace my acoustic tube? Is it removable?
Due to hygiene factors, earwax, and moisture, acoustic tubes should be replaced every 3-6 months. The acoustic tubes are easily removable from the surveillance kit, allowing for easy replacement. We offer acoustic tube replacements, which you can find here.
