1. Technical safety instructions, environment protection, safety at work Important Information for Users of the CT-DECT transceivers The CT-DECT transceiver modul has been tested for electromagnetic compatibility and is compliant with the european DECT-Standard. CT-DECT transceivers that are not intrinsically safe (explosion-protected) and therefore do not have any special hazardous duty marking must never be used in potentially explosive atmospheres.
z Do not leave the radio equipment 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 When driving a car, do not use the radio because it may distract you from the other traffic. z Charge rechargeable batteries only with the appropriate suitable charger. Observe the voltage and currency specifications.
Important Notes for operation of the CT-DECT System in the USA Please note that any changes or modifications not expressly approved by the party responsible for compliance will void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
2. Description The CT-DECT Case (8) is suitable for duplex communication over short distances between maximum 8 »mobile« users and the aircraft crew. Mobile users are using CT-DECT headsets (PP) or other headsets in conjunction with the CT-DECT Multi (PP). Communication between »mobile« users is wireless. The CT-DECT Case (8) is the central unit of the DECT system and includes the CT-DECT interface base (FP). The »mobile« users are subscribed to the CT-DECT Case with their devices (PP).

3. Operation 3.1 First commissioning At the beginning new NiMH rechargeable batteries do not deliver maximum power. Maximum power is achieved only after a few recharging cycles. Before charging rechargeable NiMH batteries, they must be completely discharged about once a month. If this procedure is not followed, rechargeable batteries will not deliver anymore full power after only a short time. Each communication device uses 3 rechargeable batteries.
3.1.2 On-air subscription of the CT-DECT device (PP) to the CT-DECT Case (8) (FP) Î NOTES ● The on-air subscription is not part of the normal commissioning and operating procedure for the system. It must be performed again only in the case a CT-DECT device (PP) that isn't subscribed to the CT-DECT Case (8) has to be used in conjunction with the CT-DECT Case (8). ● CT-DECT devices (PP) can be subscribed to only one CT-DECT Case (8), never to two or more CT-DECT Case (8) units simultaneously.
A CT-DECT device (PP) which has been deleted from the CT-DECT Case (8) memory cannot communicate anymore with the DECT system and needs to be re-subscribed to the base unit following the subscription instructions. Fig. 5 Principle of subscription (example) Timeout If a subscription is not successfully completed within maximum 2 minutes since starting the process, a »timeout« occurs.
4-second intervals, finally informs you that the subscription process has been completed successfully. If, after maximum 2 minutes, the subscription process was not successful, this is signalized by a sequence of 4 short low tones, repeating in 4-second intervals. In that case, switch off again the CT-DECT Case (8) and the CT-DECT device (PP) and repeat the entire subscription process. f.
3.2 Commissioning 3.2.1 Connecting the CT-DECT Case (8) to the aircraft The batteries of the CT-DECT Case (8) must be fully charged. a. Establishing the 9-pin plug-in connection at Figure 6, 9-pin plug-in connection at the CT-DECT Case (8) the CT-DECT Case (8) The 9-pole jack of the CT-adapter cable (figure 6) has a distortion protection. Hold the case down with one hand. Put the jack onto the 9-pin connector of the CT-DECT Case (8) and turn it until it slides a little into the connector.
3.3 Controls Duplex communication between »mobile« users After switch-on of the CT-DECT Case (8) and the CT-DECT devices (PP) and successfully completed automatic establishment of connection (see chapter 3.2.6) the units are ready for duplex communication within the working range between CT-DECT devices (PP) and CT-DECT Case (8). Microphones and headsets are permanently switched on. Each user can speak in its headset microphone and hear in the earpiece of his headset the conversation of the other users.
3.4 Operating under special climatic conditions The system is tested and approved for use within a working temperature range from -30°C up to +55°C. Exceptions apply to batteries and charging devices. Rechargeable batteries Very low or very high temperatures affect the life of rechargeable batteries. Rechargeable batteries may only be used in the temperature range from 0°C to +50°C. At temperatures below 0°C we recommend the use of alkaline batteries.
4. Maintenance and proper care 4.1 Visual inspection Inspect the system and particularly cables and connector assemblies regularly for signs of cracks, fissures, and deterioration. 4.2 Cleaning After every use the entire system should be cleaned. ATTENTION! Pay attention that no humidity could penetrate into the device during cleaning. Do not use solvents (e.g. benzene, alcohol, etc.) for cleaning! Remove loose dust with a soft brush.
4.5 Transport and shipping Use only the original packing for any transport purposes. Transport only clean and dry systems. Prior to any transport remove all rechargeable batteries from all units. 5. Replacements to be made by the user 5.1 Replacing components 5.1.1 CT-DECT Case (8) 5.1.1.1 Replacing the warning flag Unscrew the screw (figure 3/g) for removing the shackle. Remove the defective “Remove before Flight” flag and replace it by a new one. Fasten the screw again. 5.1.1.
