10 Important Information for Users of the CT-DECT transceivers When using CT-DECT transceivers for special tasks, e.g. during bomb disposal, it is the sole responsibility of the user to test and decide whether the CT-DECT transceivers can be operated without any danger. 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.
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.

z 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 might be caused due to high frequencies. 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. Do not set the volume any higher than is necessary.
2. Description 2.1 General The headset is a transmitter/receiver for wireless duplex communication between a max. of three communication parties over short distances. The range depends on the local circumstances. Up to two standard headsets are allocated to a base headset. Channel selection is effected automatically by the headsets. High protection against eavesdropping and interferences is ensured. The headset protects against harmful ambient noise and allows communication in noisy environments.
2.7 On/Off switch for the microphone The microphone can be switched on and off with the switch »Mic.–OFF–Mic.« (Fig. 3/a) at the bottom of the right-hand headset muff. Three switch positions are possible. However, communication can only be performed after the connection setup. Middle position »OFF« (receiving): The headset microphone is switched off. You can only receive. Front switch position »Mic.« (transmitting and receiving): The headset microphone is switched on.
3.4 Range warning In the case the range limit is reached a high 3-beep tone sequence is audible in the base and in the standard headset approx. every 5 seconds. When the range limit is exceeded the connection will be released. After the headsets are back again within the reception area the connection setup will be effected automatically. Finally a high double-beep tone is audible in the headsets and then a high beep tone which indicates that the connection setup has been completed. 3.
6. Headset with radio set connection 6.1 General Two communication circuits are realizable with the additional radio set connection (example Fig. 6). Both the base headset and the standard headset can be equipped with a radio set connection. Connection to the radio set is effected via a radio set adapter which e.g. consists of the following parts: – PTT button (Fig. 6/b) with fastening clip on the rear side – Connection cable with jack (Fig.
8. Safekeeping – storage Store the cleaned device in a clean, dry place at normal room temperature and in normal relative air humidity. 9. Recharging the batteries WARNING Never use battery chargers to charge non-rechargeable batteries. Never open rechargeable batteries or throw them into fire. Used (defective) rechargeable batteries are subject to special waste disposal. Do not put them in the household refuse! Use a CeoTronics charger (see section 11) to charge the 3.
10. Maintenance 10.1 Visual inspections Regularly examine the headset muffs and in particular the ear cushions frequently for signs of fractures, cracks and wear. If the headset muffs are damaged, replace the headset and send it in to CeoTronics for repair. Replace damaged or worn ear cushions in accordance with section 10.4, and, even if not damaged, every 6 months of use at the latest. 10.2 Cleaning CAUTION When cleaning ensure that no moisture penetrates inside the unit.
English 12. On-air subscription Base headset and standard headset(s) can also be used in conjunction with other CT-DECT devices resp. CT-GateCom devices. The on-air subscription of a headset to one of these devices is carried out analogous and in the sequence as described in sections 12.3....12.3.2. Going to do so, first ascertain which of the devices is the base device and which a standard device.
12.2 Principle of subscription For on-air subscription at a DECT device always the on/off switch and the subscription button(s) are used. Every time notice the special CeoTronics operating instructions for the other CT-DECT device. Î NOTE The on-air subscription is a procedure which has to be performed once only by the factory. It must be performed again only in the case a DECT device that isn't subscribed to the system has to be used within the system.
Î Note z Two ore more standard devices can never be simultaneously subscribed to the base device, they must always be subscribed one after the other. With two ore more standard devices it is recommendable to subscribe all standard devices one after the other to the base device, because a standard device can be deleted (see »Principle of subscription«). z A standard device can only be subscribed in one base device at the same time, never in two or more base devices.
