Important safety instructions
For the use of the device notice the national safety and accident prevention
regulations and the following safety instructions shown in italics in this instruction
manual.
Before using CeoTronics products read completely the appropriate operating instructions. If in doubt,
ask our technical staff.
If repair work of any kind needs to be done to CeoTronics products, arrange for it to be performed
only by the company CeoTronics or by a specialized workshop that is authorized by CeoTronics. In
all other cases our warranty and liability for the product shall lapse.
If products are operated on a mains voltage, always pull the mains plug out of the mains plug socket
before opening such products (e.g. for servicing purposes)!
Do not store CeoTronics products outside or in damp ambient conditions. At all times keep them
clean, dry and at normal air humidity. CeoTronics products must not be stored in areas with a
temperature of over +80° C (+176° F), e.g. in the summertime on the parcel shelf of a car. If not
stated otherwise, the following temperature ranges are allowed for CeoTronics products: -10 to
+55° C (+14 to +131° F) for operation, -40 to +80° C (-40 to +176° F) for storage.
Do not immerse a CeoTronics product into water, if it is not expressly specified for this purpose.
When using CeoTronics products that are equipped with connection leads ensure that the latter do
not get caught up in operational machinery or wheels!
Type-tested muffs with a high degree of passive noise attenuation are used for CeoTronics headsets
with headset muffs. If not stated otherwise, it is our experience that the passive noise attenuation of
the headset muffs is reduced by approx. 3 dB due to the electronics that are integrated into the
headset muffs. As a rule no empirical values are available for non-standard products.
Information to noise attenuation values, which result from representative measurements of a
named place, are to be regarded as orientation values, which cannot be guaranteed, if no
"Type Examination Certificate" is present.
Note that it acts with electronic communication systems of CeoTronics, not around "Personal
Protective Equipment" in the sense of the "PPE Directive 89/686/EEC", if not differently
indicated.
At very high noise levels that exceed the passive protective effect of the headset muffs we
recommend that ear plugs be worn as an additional measure. If in doubt, ask your safety officer or
company doctor. Full noise attenuation exists only if the muff padding is in perfect condition. This
should be replaced at the latest after every 6 months of use.
In the case of headsets with headset muffs that protect against harmful ambient noise and that are
not equipped with additional electronics for level-limited ambient sound reception, take heed that the
audibility of warning signals, warning calls etc. is also impaired!
CeoTronics products that are not intrinsically safe (explosion-proof) and therefore have no special
explosion-proof designation must never be operated in potentially explosive environments (e.g.
when refuelling cars, aircraft etc.). Devices that are not explosion-proof can unintentionally trigger off
explosions in such areas!
If you are a cardiac pacemaker carrier, before operating a transmitter/receiver ask the manufacturer
of your cardiac pacemaker for information about any impairment that might be caused due to
high frequencies.
For safety reasons reception volumes in excess of 85 dB(A) are possible with a whole series of
CeoTronics products. However, these can be regulated by the user. Do not set the volume any
higher than is necessary. A very high volume setting can lead to damaged hearing, particularly if it is
continuous. For high volumes or noise levels wear additional ear plugs. If in doubt, ask your safety
officer or company doctor.
