⚫ Let devices that are designed for outdoor use during use outdoors always closed (e.g. CT-DECT
Case) and close unused ports with appropriate cover – if available.
⚫ Do not store CeoTronics products in the open air or in damp ambient conditions. At all times keep
them clean, dry and at normal air humidity. CeoTronics pro- ducts 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 acceptable for CeoTronics products: -10 to
+55°C for operation, -40 to +80° C (-40 to +176° F) for storage.
⚫ Pay attention that no humidity could penetrate into the device during cleaning. Do not use solvents
(e.g. benzene, alcohol, etc.) for cleaning! Safe operation requires clean devices. Ensure that the
devices (microphones, connectors etc.) are clean and in good condition at all times.
Risk of injury by connection leads!
⚫ When using CeoTronics products that are equipped with connection leads ensure that the leads do
not get caught up in operational machinery or wheels!
Risk of injury by speaker volume!
⚫ Please, note that in some audio devices (e.g. radios) very loud signaling beeps could be present as
the radio is switched on. There are various types of devices generating a series of tones in different
loudness levels. It may be necessary to adjust the volumes of the tones separately. These tones
could damage your hearing if they are set too high. Therefore, adjust signaling beeps to a
convenient level as desired before starting to use CeoTronics accessories. Follow the instructions of
the audio device manufacturer's operating manual to adjust the signaling beeps.
⚫ 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. After switching on the
communication system, set the reception volume to approx. 1/2 the available loudness volume and
then test the speaker volume, e.g. by opening the squelch on the radio set.
⚫ 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
earplugs. If in doubt, ask your safety officer or company doctor.
Road traffic hazard!
⚫ Do not leave CeoTronics products lying around loose in cars, e.g. on the parcel shelf. Stow these
products in a suitable, safe place in the car so that they do not present a danger to you or to other
occupants of the car, if emergency braking is effected.
⚫ When driving a car, do not use the radio because it may distract you from the other traffic. Never use
a CeoTronics product (headset, insert earphone, induction receiver etc.) that will impair your hearing.
Impairment of flight operation!
⚫ When on board an airplane always keep a transmitter/receiver switched off. Operation of the
transmitter / receiver could affect the safety of the aircraft, and it is therefore prohibited. Never
operate electronic devices on board an aircraft without the express approval of an authorized
member of the cabin crew.
⚫ The CT-DECT GateCom Compact must always be removed from the aircraft once the intercom
communication is completed. Never remove the warning flag „Remove before flight" from the CT-
DECT GateCom Compact.
Impairment of radio transmission!
⚫ Transmit only when it is necessary. Unnecessarily occupying a channel can prevent the transmission
of vitally important information.
Risk of explosion!
⚫ CeoTronics products that are not intrinsically safe (explosion-proof) and there- fore have no special
explosion-proof designation must basically not be operated in potentially explosive environments.
Potentially explosive atmospheres can arise, for example, in refuelling areas or in storage and
transport facilities for fuels and chemicals! Devices that are not explosion-proof can trigger off
explosions in such areas!
