1. 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.
z Before using CeoTronics products read completely the appropriate operating instructions. If in doubt,
ask our technical staff.
z Use only CeoTronics products without damage and wear.
z 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.
z 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.
z Do not immerse a CeoTronics product into water, if it is not expressly specified for this purpose.
z When using CeoTronics products that are equipped with connection leads ensure that the latter do
not get caught up in operational machinery or wheels!
z 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!
z Connect CeoTronics accessories to a device or disconnect them from a device only when the device
is switched off. In the case of intrinsically safe products (explosion-proof) this must always take place
outside of the potentially explosive area. Otherwise the consequence could be an unintentional
explosion!
z Please note that in some radios very loud signalling beeps could be present already in the
moment of switching the radio on. There are various types of radios generating a series of
signals in different loudness levels. It may be necessary to adjust the volume of the
signalling beeps separately. These beeps could damage your hearing if they are set too high.
Therefore, adjust signalling beeps to a convenient level as desired before starting to use
CeoTronics accessories. Follow the instructions of the radio manufacturer’s operating
manual to adjust the signalling beeps.
z 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 audible 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 ear
plugs. If in doubt, ask your safety officer or company doctor.
z 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.
z Keep CeoTronics products out of the reach of children and any other persons who are not familiar
with the handling and operation thereof.
z Packaging materials, e.g. filling materials and plastic bags are not toys and have to be kept out of
the reach of children. There is a risk of children ingesting them and choking!
z Safe operation requires clean devices. Ensure that the devices (microphones, connectors etc.) are
clean and in good condition at all times.
z CeoTronics products may only be used for the specific application envisaged.
4
z Should equipment, supplied by CeoTronics, be definitely put out of service you may return it to
CeoTronics. We ensure recycling and/or disposal of outdated equipment in compliance with
the applicable environment protection law.
z Keep these operating instructions for later use.
2. Description
General
The CT-ClipCom Digital is a binaural communication system for use with radio equipment. The PTT
buttons (PTT=push-to-talk) of the system are used to transmit PTT commands to the radio unit or
similar communication systems.
The following two system configurations are available:
CT-ClipCom Digital ear microphone consisting of one ear microphones plus one earphone, a PTT
transmit button, and an optional CT-Wireless-PTT
CT-ClipCom Digital gooseneck microphone consisting of one earphone plus one earphone with
gooseneck microphone, a PTT transmit button, and an optional CT-Wireless-PTT
The earphones/ear microphones are electro-acoustic transducers, used either as microphones (for
transmitting) or earphones (for receiving), worn in the ear with ear plugs.
Optional can be worn the ear microphone in the ear with individually formed ear moulds.
The system is equipped with ambient sound reception (ASR) for both sides.
The employment of ASR makes a level-dependant sound absorption possible.
Power is provided by the radio unit.

2.4.1 Information regarding hearing protection (Only for operation with individually ear moulds
with filter SKLD26)
Manufacturer: CeoTronics AG
Type designations: CT-ClipCom digital BoomMike and/or EarMike with p/n 6015068, 6015069 &
options
2.4.1.1 Fitting accuracy of ear moulds
The CT-ClipCom digital communication system combined with personalised ear moulds / earpieces is
considered a personalised hearing protector which has been tested and certified within the scope of the
EC-type approval as personal protection equipment in the meaning of the European Directive
89/686/EG.
The sound insulating effect of a personalised ear mould depends principally on the proper accurate fit
and the personal ergonomics of the user.
For this reason, CeoTronics recommends to check the fitting accuracy of personalised ear moulds by
making acoustic measurements. Only this way it is possible to assure an appropriate sound insulating
effect of your ear mould.
For this purpose CeoTronics has developed a special testing system.
A sound insulation measurement made by this testing system, duly documented by a test certificate,
proves that the personalised ear moulds provide sufficient sound insulation.
Please note that this is a qualitative measurement and therefore the results must not necessarily
coincide with statistically ascertained values of subjective sound insulation experienced by 16 test
persons in the type approval test, as these are two different measuring methods.
Experience shows that that actual personal sound insulation values are slightly higher than the values
measured by the CeoTronics testing system. As the lower limits are used the minimum sound insulation
values of the EN 352-2 Standard.
In rare individual cases it is possible that no satisfactory sound insulation can be achieved in spite of
maximum care exercised in the process of taking impressions and manufacturing the ear moulds.
In such cases our earplugs can be used, however no specific certification is available for use together
with the CT-ClipCom digital communication system.
Wear of ear moulds varies individually; we recommend regular examination by measuring the moulds
with the CeoTronics testing system or replacement of your personalised ear mould after 2 years.
Kindly contact our customer consultants in case you want to test your personalised ear mould or clarify
any further questions regarding this subject.
2.4.1.2 Conformity to Standards
This hearing protection complies with the requirements of the European Standard EN 352-2 and EN
352-7:2003. It has been designed, manufactured, and tested according to the state of the art and in
compliance with the DIN EN ISO 9001 Standard.

CT-ClipCom Digital ear microphone
The DNR electronics (Digital Noise Reduction) filter and eliminate ambient noise from the voice
signal.
Radio messages are heard on both sides. In case a PTT transmit button is actuated the ear
microphone in the right ear switches from earphone to microphone operation. Consequently, the
ambient sound reception (ASR) of this ear microphone is not active.
CT-ClipCom Digital gooseneck microphone
The noise cancelling gooseneck microphone works without DNR function.
During activation of the PTT button, ambient sound reception is active on both sides.
4. Safekeeping – storage
After use, keep the cleaned devices in a clean and dry place at normal room temperature and at normal
relative air humidity.
5. Maintenance
5.1 Visual inspections
Check the CT-ClipCom Digital and particularly the cables and connectors periodically for signs of
fractures, cracks and wear. Check ear moulds and earphones/ear microphones after every use for
pollution.
Pollution can be the cause for skin irritation and malfunction.
5.2 Cleaning
ATTENTION!
When cleaning, make sure that no moisture penetrates inside the device. Do not use any
solvents (e.g. benzine, alcohol, sterilizing agents, etc.). After cleaning, keep earphones/ear
microphones unpacked until completely dry.
Obstructed sound channels of ear moulds and ear plugs cause poor communication in transmitting
(speaking) and reception (hearing). For periodical cleaning of components we recommend special
cleaning tissues (see chapter 6).
Clean the contacts of connectors with a commonly available contact cleaning agent.
Ear moulds and Earphones
Obstructed sound channels of ear moulds and earphones cause poor reception. For regular cleaning
(after every use) we recommend the use of special antiseptic cleaning tissues (see item 7), an
appropriate cleaning spray, or soft clean cloths and pure water with some dishwashing liquid.
Do not use solvents for cleaning purposes.
For a basic cleaning of ear moulds we recommend a cleaning bath once a week (effervescent tablets;
e.g. Detax Smarttabs) or ultrasonic bath.
5.3 Changing the protective cover of the gooseneck microphone
Check the protective foam cover periodically for pollution, wear and deformation and replace it, if
necessary. It can be easily pulled off the microphone.
