USERS GUIDE
WARNINGS/CAUTIONS
Headset Volume
Before wearing the headset, turn the volume down, then put on the headset and slowly turn the volume up to reach a
comfortable level that provides clear communications.
To prevent possible hearing damage DO NOT operate the headset at full volume for extended periods, the louder a
sound is, the less time it takes to cause hearing damage.
The headset provides hearing protection by attenuating loud sounds, however it is recommended that you do not turn
up the volume so high that you cannot hear what is around you such as alarms, sirens, or warning signals.
If you experience a warming sensation in either earcup, remove the headset immediately and contact Setcom
customer service.
