Before using CeoTronics products, read completely the appropriate operating instructions. If in doubt, ask our technical staff. Keep this document for later use. Use CeoTronics products only without damage and abrasion. 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. Keep CeoTronics products out of the reach of children and any other persons who are not familiar with the handling and operation thereof. CeoTronics products may only be used for the specific application envisaged. Safe operation requires clean devices. Ensure that the devices (microphones, connectors etc.) are clean and in good condition at all times. 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 We ensure recycling and / or disposal of outdated equipment in compliance with the applicable environment protection law. Product damage!

Do not immerse a CeoTronics product into water, unless expressly specified for this purpose. Connect CeoTronics accessories to a device or disconnect them from a device only after switching the device off, unless otherwise described in the operating instructions. dok1702-us-07-0221 2 / 20 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

+55C 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 manufacturers 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!

dok1702-us-07-0221 3 / 20 It is important that you strictly observe the guidelines, arrangements and regulations applicable to your area of activity!

Risk of electric shock!

Before opening line voltage operated products (e.g. for service purposes), always disconnect first the mains plug from the mains socket!

Use CeoTronics products only in undamaged condition. In case of any kind of damage, refrain from further using the CeoTronics product and have it repaired. Adverse effect on cardiac pacemakers!

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 could be caused due to high frequencies. Rechargeable batteries and batteries!

Observe the environmental regulations when handling storage batteries! Do not throw used

(defective) storage batteries into the domestic refuse. Observe the battery ordinance (BattV). Risk of injury by Rechargeable batteries and batteries!

Insert the rechargeable batteries only after having read and understood all safety instructions. Rechargeable batteries imply potential risks, which could cause physical injury and material damage. Never intend to open a rechargeable battery and never throw it into open fire. Ensure that contacts and charging sockets of the rechargeable battery do not cause short circuit (risk of fire and injury) by bridging (bent-open paper clip, bunch of keys or similar). In such a case, the guarantee is void. Transport spare rechargeable batteries in electrically non-conductive packing material in order to avoid shorting the rechargeable batteries. Keep the rechargeable batteries away from persons who are not familiar with their handling and use

(e.g. children). Charging rechargeable batteries in potentially explosive areas is strictly prohibited (risk of explosion!). Charge and change rechargeable batteries only in areas where no explosive gases, vapours, or dusts could be present in combination with air. Damage to charger or rechargeable batteries!

Charge rechargeable batteries only using the corresponding appropriate CeoTronics charger. Regard voltage and current data, also on the mains side (e.g. 230 V AC or 115 V AC). Never use the battery charger for charging non-rechargeable batteries. Chargers are neither waterproof nor dust-tight and need protection against water, rain, and contamination. Use them only in the appropriate environment, intended for the system. Dont cover the ventilation openings. Dont charge rechargeable batteries outdoors. Radio Software (firmware) Risk of malfunction!

Please note that the function of radio accessories is depending on the software settings set up in your radio. Be careful with software updates and / or changes to the software settings. If you update the radios software, or if you change the software settings, check first on a radio that the radio accessory is still functioning properly after these changes. It is possible that the receiving volume of some radios is not satisfactory. In these cases, we suggest you check if an increase of the receiving volume is possible via the parameters in the audio profile of your radio. Follow the information of the radio manufacturer!

If you have any further questions in regards to this subject, do not hesitate to contact our sales back office. dok1702-us-07-0221 4 / 20 Important safety information concerning the use of CT-DECT digital radio systems!
