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 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.
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 Multi (PP) is a two-way radio for wireless communication over short distances and is used in conjunction with a headset and the CT-DECT Case (8) (FP). The working range between the CT-DECT Multi (PP) and the CT-DECT Case (8) depends on the local conditions. The "CT-DECT Multi (PP)" is used normally with his associated CT-DECT Case (8) (FP) and must be subscribed to it.

2.2 Technical description Figure 2 radio CT-DECT Multi (PP) 1 2 3 4 5 6 Fall protection cord 6-pole jack for a CT communication set On/off switch and volume control (rotary knob). The unit is switched off if the rotary knob is set fully counter-clockwise (position » z «). The volume control is used to adjust the volume for the communication set. Bank of 5 pushbuttons.
2.2.1 Power supply Power for the CT-DECT Multi is supplied either by three rechargeable batteries or by 3 alkaline batteries in the battery compartment. 2.2.2 Audio signals used Two different audible tones are used for signaling the operating status via the communication set connected to the device. The tone for the indication of positive operating status has a higher frequency than the tone for the indication of negative operating status.
Figure 6 3. Operation 3.1 First commissioning PLEASE NOTE: Before inserting rechargeable batteries, please read the safety instruction. 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.
c. Take the three NiMH batteries out the battery compartment. Charge the rechargeable batteries with the charger. d. After charging: When inserting recharged NiMH batteries, attend to the polarity. Fit the two hooks of the battery compartment cover into the two openings at the compartment’s bottom (Fig. 8) and press the cover against the compartment until it is engaged.
3.1.2 On-air subscription of the CT-DECT Multi (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 Multi (PP) that isn't subscribed to the CT-DECT Case (8) has to be used in conjunction with the CT-DECT Case (8). ● A CT-DECT Multi (PP) can be subscribed to only one CT-DECT Case (8), never to two or more CT-DECT Case (8) units simultaneously.
Time Out 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 Multi (PP), repeating in 4-second intervals. After a timeout all CT-DECT Multi (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.
3.2 Commissioning 3.2.1 Fasten the CT-DECT Multi (PP) on your clothing Fasten the CT-DECT Multi at a suitable place on your clothing. Take care that your mobility is not impaired and the CT-DECT Multi (PP) can be operated without any problem. 3.2.2 Connect the headset to the CT-DECT Multi (PP) Put the headset on. Fasten the PTT button of the headset with the clip on its back side at a suitable place on your clothing.
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 3.2.3) 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.
4.3 Faults, causes, corrective actions Fault CT-DECT Multi (PP), after switch-on, no tone sounds in the headset CT-DECT Multi (PP), life of rechargeable batteries is too short After switching the system on, automatic establishment of connection is not completed successfully 4.
b. Mounting the cover: insert the two hooks of the battery compartment cover into the openings at the compartment’s bottom (figure 8). Fold the cover upwards and press it against the battery compartment until it is engaged. 5.1.4 Replacing the potentiometer knob a. Rotate the potentiometer knob anticlockwise into OFF position (figure 10). b. Unscrew the stud screw (M3) with the help of a hexagon socket head wrench SW 1.5 (figure 11). c. Pull the potentiometer knob off the shaft and replace it.
