3 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. Unprotected CT-DECT transceivers can trigger explosions unintentionally in these areas. CeoTronics does not assume any liability for damage to property and personal injuries of any kind that can arise through the above mentioned or any other incorrect use of the CT-DECT transceivers. 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 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 immerse the radio equipment into water. 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 Radio equipment that are not intrinsically safe (explosion-proof) and therefore have no spe-cial explosion-proof designation must never be operated in potentially explosive environ-ments (e.g. when refueling cars, aircraft etc.). Devices that are not explosion-proof can unin-tentionally 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. z If you are a cardiac pacemaker carrier, before operating a transmit-ter/receiver ask the manufacturer of your cardiac pacemaker for informa-tion about any impairment that might be caused due to high frequencies. z Before starting to operate the device in sensitive areas like e.g. aboard airplanes or in hospitals etc., please check first if it is permitted to use it in these environments. For use aboard an airplane a Type Certificate (TC) or a Certificate of Nonobjection (CO) must be available. Should the communication equipment not be homologated, its use aboard an airplane is strictly prohibited as it could jeopardize the safety of the airplane. Never put electronic devices into operation aboard an airplane without obtaining prior approval from the cabin crew.
4 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. Never use the charger to recharge non-rechargeable batteries. z When handling rechargeable batteries comply with environmental protection regulations ! Never attempt to open a rechargeable battery and never throw a rechargeable battery into fire. Expended (defective) rechargeable batteries are subject to compulsory regulated waste disposal. Do not put them in the household waste! z Ensure that a short-circuit (risk of fire or injury) is not created across rechargeable battery terminals or charging sockets by a short-out (bent-open paper clip, bunch of keys etc.). In such an event the warranty shall lapse. Transport any spare rechargeable batteries in an electrically non-conducting package in order to avoid short-circuiting the rechargeable batteries. z Keep the radio equipment and rechargeable batteries out of the reach of children and any other per-sons who are not familiar with the handling and operation thereof. z Safe operation requires clean devices. Ensure that the devices (microphones, connectors etc.) are clean and in good condition at all times. z The radio equipment may only be used for the specific application envisaged. 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.

11 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. If one or more recharge-able batteries are not fully charged, this will affect the reliability of the entire system. As it is not possible to determine which one of the rechargeable batteries is in poor condition, the complete set must be replaced. Proper care and handling helps controlling the number of rechargeable batteries in use. The life of rechargeable batteries may vary as a result of daily recharging, natural ageing, and varying operating conditions. 3.1.1 Recharging the NiMH rechargeable batteries 3.1.1.1 General The rechargeable NiMH batteries in the device should only be charged with the charger supplied with the system. Otherwise the rechargeable batteries may be damaged. The charger is neither watertight nor dust-proof. Protect it against water, rain and dirt. The charger may only be used in rooms with nor-mal relative air humidity and temperature. Do not cover up the charger. Warning z Never use battery chargers to charge non-rechargeable batteries. Never open rechargeable batteries or throw them into fire. Do not open charger. The repair is permitted only by the manufacturer. z Never charge a rechargeable battery in areas with an explosion risk – an explosion may re-sult. Charge rechargeable batteries only inside buildings or similar environments where no dangerous concentrations of volatile vapors are present. The three NiMH batteries are in the battery compartment of the CT-DECT Case (8). For charging they have to be removed from the battery compartment. a. Switch off the device CT-DECT Case (8). b. Remove the cover from the battery compartment (Fig. 3). c. Take the three NiMH batteries out the battery compartment. Charge the rechargeable batteries with the charger. e. After charging: When inserting the charged NiMH batteries notice the polarity. Close the battery compartment.
12 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. Î NOTES z Two ore more CT-DECT devices (PP) can never be simultaneously subscribed to the CT-DECT Case (8), they must always be subscribed one after the other. With two ore more CT-DECT devices (PP) it is recommendable to subscribe all devices one after the other to the CT-DECT Case (8), because a device can be deleted (see 3.1.2.1 »Princi-ple of subscription«). z Comply with the instruction step sequence. z After subscription all new subscribed devices have to be switched off again. The on-air subscription procedure is performed on the CT-DECT Case (8) and the CT-DECT devices (PP) manually by means of operating elements. The CT-DECT Case (8) is the unit to which the maxi-mum eight (8) CT-DECT devices (PP) of a system need to be subscribed to. The CT-DECT Case (8) is equipped with two transceiver modules, the both subscription buttons (Fig. 3/b,c,i) and is able to control max. eight CT-DECT devices (PP). In each case max. four CT-DECT de-vices (PP) are allocated to one transceiver module. Every four CT-DECT devices (PP) are assigned in groups to the subscription buttons (figure 4/b, c). The function of the outside button (figure 4/i) is identi-cal to that of the subscription button shown in figure 4/b. 3.1.2.1 Principle of subscription Four CT-DECT devices (PP) can be assigned to each transceiver module in the CT-DECT Case (8). The four CT-DECT devices (PP) assigned to a transceiver module should always be subscribed in groups, but of course individually one by one. Should a fifth CT-DECT device (PP) be subscribed to one and the same transceiver module, then the CT-DECT device (PP) subscribed first would be deleted from the transceiver module’s memory (see example in figure 5). Î PLEASE NOTE: The subscription procedure for a group of maximum four CT-DECT units (PP) which are sub-scribed with the help of button “2” (figure 4/c) differs from the procedure when subscribing CT-DECT devices (PP) with the “1/external” buttons (figure 4/b, i). The subscription procedure can be performed while communicating without any need to switch off and open the CT-DECT Case (8). The procedure, applicable for subscribing maximum four CT-DECT devices (PP) with button “2” (figure 4/c) is described in chapter 3.1.2.2 and for subscribing the other maximum four CT-DECT devices (PP) with the help of buttons “1/external” (figure 4/b, i) in chapter 3.1.2.3.
13 A CT-DECT device (PP) which has been deleted from the CT-DECT Case (8) memory cannot commu-nicate 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. The timeout is signalized by a sequence of 4 short low tones in the headset of the CT-DECT device (PP), repeating in 4-second intervals. After a timeout all CT-DECT devices (PP) subscribed to a transceiver module need to be subscribed anew to the CT-DECT Case (8). In the event of only one CT-DECT unit (PP) the subscription of this single CT-DECT unit (PP) has to be repeated. 3.1.2.2 Example of subscribing a CT-DECT device (PP) with subscription button 2 (figure 4/c) The following describes the procedure for subscribing a CT-DECT device (PP) to a CT-DECT Case (8) with the subscription button »2« (figure 4/c). The subscription of the remaining three CT-DECT devices (PP) (maximum four units) with button »2« is done likewise. Î PLEASE NOTE: After successful subscription, all CT-DECT devices (PP) and the CT-DECT Case (8) must be switched off again before putting the DECT system into operation. a. Make sure all CT-DECT devices are switched off. b. Unscrew the two screws (figure 2/e, g) on the CT-DECT Case (8) and remove the two shackles (fig-ure 2/c, i) from the case. Unlock the two latches (figure 2/a) and open the case. c. Leave the CT-DECT unit (PP) still switched off. d. Press the subscription button »2« (figura 4/c) inside the CT-DECT Case (8) and keep it depressed. Switch on the CT-DECT Case (8) with the green push-button (figure 4/d) while the subscription but-ton is depressed and keep it depressed for at least another 5 seconds after switch-on. Then release the subscription button and continue directly with step »e« in order to avoid a »timeout«. e. Press the subscription button on the CT-DECT device (PP) and keep it depressed. Switch the CT-DECT device (PP) on while depressing the subscription button and keep it depressed for at least another 5 seconds since switch-on until you hear a descending 5-tone sequence in your headset. Then release the button. The subscription process has been initiated and you hear in the headset of the CT-DECT unit (PP) about every 2 seconds an intermittent high beep. An ascending 5-tone sequence, which repeats in
14 4-second intervals, finally informs you that the subscription process has been completed success-fully. If, after maximum 2 minutes, the subscription process was not successful, this is signalized by a se-quence 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. After successful completion of the subscription process, switch off again the CT-DECT de-vice (PP) and the CT-DECT Case (8) before commissioning the units (chapter 3.2.6). Î PLEASE NOTE: The subscription procedure described in chapter 3.1.2.3 while the communication system is operating applies only to the four CT-DECT devices (PP), which are being subscribed via the inside subscription button »1/external« (figure 4/b) or the one on outside of the case (figure 4/i). 3.1.2.3 Example of subscribing a CT-DECT device (PP) during operation When subscribing maximum four CT-DECT devices (PP) to the CT-DECT Case (8) using the subscrip-tion button “1/external” (figure 4/b, i) the CT-DECT Case (8) must not necessarily be in switched-off condition. Subscription can be accomplished while the CT-DECT Case (8) is operating. This makes it possible that the maximum four users, who already subscribed their CT-DECT devices (PP) with the help of the subscription button 2, can continue to operate while additional CT-DECT devices (PP) are being subscribed to the CT-DECT Case (8) via the “1/external” subscription buttons (figure 4 b/i). The subscription process can be aborted at any time by simply pressing the external subscription button (figure 4/i) during the subscription process. Both subscription buttons (figure 4/b, i) have equality of access. For a fast subscription when in opera-tion, normally the external subscription button (figure 4/i) located on the outside of the case is used, so that the case does not need to be opened. The following example describes the subscription process using the external subscription button (figure 4/i) located on the outside of the CT-DECT Case (8). Other CT-DECT devices (PP) (max. four) are subscribed likewise with this button (figure 4/i). a. Firstly, leave the CT-DECT device (PP) switched-off. b. Press the external subscription button (figure 4/i) of the switched-on CT-DECT Case (8) and keep it depressed for at least 5 seconds. Then release it and continue directly with step »c« in order to avoid a »timeout« (see chapter 3.1.2.1). The LED of the subscription button (figure 4/i) lights up. If a »timeout« occurs, the LED starts to flash. c. Press the subscription button of the CT-DECT device (PP) and keep it depressed. Switch the CT-DECT device (PP) on while depressing the subscription button and keep it depressed for at least another 5 seconds since switch-on until you hear a descending 5-tone sequence in your headset. Then release the button. The subscription process is initiated and you hear in the headset of the CT-DECT device (PP) about every 2 seconds an intermittent high beep. An ascending 5-tone sequence, which repeats in 4-second intervals, finally informs you that the subscription process has been completed successfully. After a successful subscription the LED of the subscription button (figure 4/i) on the CT-DECT device (PP) goes out. If, after maximum 2 minutes, the subscription process was not successful, this is signalized by a se-quence of 4 short low tones, repeating in 4-second intervals. If the subscription process is not completed successfully, the LED of the subscription button (figure 4/i) starts flashing. In that case switch the CT-DECT device (PP) off again and repeat the entire proc-ess. d. After successful completion of the subscription process, switch the CT-DECT device (PP) again off before commissioning the unit; the CT-DECT Case (8) must not be switched off.
15 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 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 con-nector. With it, the correct plug-in position has been found. Now push the jack into the connector until it engages audibly. To disconnect the plug-in connection, hold the case down with one hand and pull the jack out of the connector. b Connect the CT-DECT Case (8) with the CT adapter cable to the intercom connector of the aircraft. Figure 6, 9-pin plug-in connection at the CT-DECT Case (8) Î PLEASE NOTE: During outdoor operations keep the CT-DECT Case (8) always closed! CAUTION! The CT-DECT Case (8) may be connected to an aircraft only with the flag “Remove before flight” attached. 3.2.2 Switching-on of CT-DECT Case (8) and CT-DECT device (PP) Switch-on, establishing connection, adjusting the volume Î PLEASE NOTE: Applies to CT-DECT devices (PP) which are subscribed to a CT-DECT Case (8) a. First switch on the CT-DECT Case (8) using the green push-button (figure 4/d). The CT-DECT Case (8) starts now an initialization process during which it may not be switched off. After initialization the pilot lamp (figure 4/e) lights up. If the pilot lamp (figure 4/f) flashes, the voltage of the batteries in the CT-DECT Case (8) is low and needs to be recharged. b. Switch on the CT-DECT devices (PP) you want to communicate with. After switch-on you will hear a high beep in the headset. After this, synchronization, i.e. the search process, starts between the CT-DECT Case (8) and the CT-DECT devices (PP), the duration of which may vary. While this process is under way, a high-low tone sequence will be heard every second in the headsets, indicating, that the CT-DECT devices (PP) are seeking their CT-DECT Case (8). After successful synchronization - i.e. a CT-DECT device (PP) found its CT-DECT Case (8) - the high-low tone sequence falls silent and a high double beep is heard in the headset. CT-DECT Case (8) and CT-DECT device (PP) establish now automatically the connection between one another. As soon as the connection is established a final high beep will be heard in the headset. This indicates that the units are ready for duplex communication within the working range between CT-DECT device (PP) and base unit.
16 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 communica-tion 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. Adjust the communication volume with the volume control for your headset earpieces. Never adjust the volume higher than necessary for clear and proper communication. Communication between »mobile« users and the aircraft intercom system With the help of the PTT button on the headset, communication between »mobile« users and the crew of the aircraft is possible, while the PTT button is pressed. Pressing the »COM ON/OFF« buttons on the CT-DECT devices (PP) once establishes communication between »mobile« users and the crew aboard the aircraft; pressing a second time cuts the communica-tion off. If the communication between »mobile« users and the aircraft crew is OFF, a high double beep sounds in the headset after pressing the buttons. Now, communication is switched on. If the communication between »mobile« users and the aircraft crew is ON, a low double beep sounds in the headset after pressing the buttons. Now communication is cut off. Only the »mobile« user establishing the intercom connection is connected with the crew of the aircraft and only he can terminate the connection.
17 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. As CT-DECT devices (PP) are used close to the body, temperatures below 0°C are rarely seen. However, the CT-DECT Case stands (is suspended) in open air; therefore we recommend at very low temperatures the use alkaline batteries instead of rechargeable ones. Mobile (plug-type) battery charger Working temperature range: 0°C – 25°
18 4. Maintenance and proper care 4.1 Visual inspection Inspect the system and particularly cables and connector assemblies regularly for signs of cracks, fis-sures, 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. Clean the outside of components, if necessary, with an appropri-ate clean cloth, only lightly moistened with clear water, and then rub it down thoroughly. If heavily soiled, a few drops of rinsing agent may be added. Clean the connector pins with a commercial clean-ing agent. 4.3 Faults, causes, corrective actions Fault Cause Corrective action CT-DECT Case (8), no LED lights up after switch-on Rechargeable batteries are completely run down or defec-tive Recharge or replace recharge-able batteries CT-DECT Case (8), life of re-chargeable batteries is too short Rechargeable batteries are de-fective Replace rechargeable batteries After switching the system on, automatic establishment of con-nection is not completed suc-cessfully CT-DECT device (PP) is not subscribed to the CT-DECT Case (8) Perform subscription procedure 4.4 Storage The equipment can be stored at temperatures from -40°C up to +80°C.
