A Safety information
All Ceotronics Headsets TC 917 use type approved passive ear mulls. The integration of the
electronic devices in the ear muffs can reduce the passive noise attenuation hy approx.
3 dB. With very high noise levels we strongly recommend the additional use of earplugs to
prevent hearing damage. If you are in doubt please contact your safety officer or works
medical practitioner. Effective hearing protection is only guaranteed when you are wearing
the headset permanently when in a designated high noise area. Replacement of the ear
cushions after a period of 6 months of use is recommended to achieve optimum hearing
protection. Please note, that when using headsets with ear muffs which protect against
harmful ambient noise, and are not equipped with the feature for ambient sound reception,
also the hearing of warning signals, warning cries etc. will be impaired.
Do not adjust the receive volume of your Transceiver Headset TC 917 to a level higher than
necessary. Excessive receive volumes over long periods can damage your hearing.
When using Ceotronics products follow the safety information given on the supplement sheet
”Important Safety Warnings". This supplement sheet is delivered with each Ceotronics
product. To ensure proper operation and along lifetime for the product, please follow the
operating instructions. For further information please contact our experts.
