83. On-air subscription3.1 GeneralÎ NOTEThe on-air subscription is a procedure which has to be performed once only by the factory. Itmust be performed only in the case of an error or if another CT-DECT Multi will be used in thesystem. If this is not the case skip the sections 3....3.2.2 and start with section 4.Each unit is equipped with a DECT module and has its own identification number. First of all anallocation must always take place between the base unit and the maximum of two standard units. Thissubscription procedure, which has to be perfomed once only, is performed on the base unit and themaximum of two standard units manually by means of a procedure carried out by the operator.If a third standard unit is subscribed to the base unit, the standard unit that was subscribed in first isdeleted from the data base of the base unit.Once the subscription procedure has been successfully concluded, the identity of the communicationpartner is stored in the data base of the unit. The standard unit stores one base unit. The base unitstores the last two successfully subscribed standard units.Time OutIf a base unit or a standard unit is set to subscription mode and this is terminated or not completed after2 minutes without the subscription procedure having been successfully concluded a »Time Out«occurs. The »Time Out« effects that the data bases of a max. of two stored standard units available inthe base unit and in the case of the standard unit the available data base for the stored base unit aredeleted. After a »Time Out« the subscription procedure must be restarted.3.2 On-air subscriptionÎ NOTESzTwo standard units can never be simultaneously subscribed to the base unit, they mustalways be subscribed one after the other. If two standard units are used in conjunction withthe base unit always both standard units must to be subscribed one after the other to thebase unit, never one standard unit only.zAfter subscription the units have to be switched off again.3.2.1 On-air subscription of the first standard unita. Connect he communication set to the jack (Fig. 1/a) on the upper side of the unit.b. On the base unit simultaneously press the both subscription buttons located at the begin and end ofthe the push-button bank (Fig. 1/c). Keep the two subscription buttons pressed and switch on thebase unit by means of the on/off switch and volume control (rotary knob Fig. 1/b). The on-airsubscription procedure will be signalled by a 5-beep tone sequence via the communication set. Thenimmediately carry out step »c«, otherwise a »Time Out« may occur (see section 3.1).c. On the standard unit simultaneously press the both subscription buttons located at the begin andend of the the push-button bank (Fig. 1/c). Keep the two subscription buttons pressed and switch onthe standard unit by means of the on/off switch and volume control (rotary knob Fig. 1/b).After approx. 30 seconds a high double-beep tone can be heard in the communication set of thebase unit and in the communication set of the standard unit. This indicates that the on-airsubscription has been successfully completed. A second high double-beep tone finally reports thatthe standard unit has synchronized itself with the base unit. Afterwards switch off both units.3.2.2 On-air subscription of the second standard unitEnsure that the standard unit that was subscribed in first (section 3.2.1) is switched off. Repeat thesubscription procedure for the base unit and for the second standard unit as described in section 3.2.1.Afterwards switch off all units.
94. Commissioning and operation4.1 Connecting the headset or hand microphonea. Connect he communication set to the jack (Fig. 1/a) on the upper side of the unit.b.

Place the unit on a suitable place of your clothing.Î NOTEProtect the unit against dampness.4.2 Switching on, synchronization, adjusting the speaker volumea. Switch on the units by means of the on/off switch and volume control (rotary knob Fig. 1/b).Synchronization: A high beep tone is audible in the communication set connected to the base unitand to the standard unit approx. 10 seconds after switching on. The synchronization procedure thenbegins, i.e. the base unit seeks its standard unit. This synchronization procedure can last approx. 30seconds.Upon completion of synchronization – i.e. the base unit has found its standard unit – a high double-beep tone sounds in the communication set of the standard unit and of the base unit. Subsequentlythe connection setup between the units is effected automatically and the units are ready for duplexcommunication. In the case of two standard units two high double-beep tones are audible in thecommunication set of the base unit upon successful completion of synchronization.b. On voice reception adjust the speaker volume for your communication set by means of the on/offswitch and volume control knob (rotary knob).Î NOTEAlways leave the units switched on as long as you work with the communcation system so thatimmediate availability of the system is provided.c.
