CeoTronics CT-DECT Multi Operating Instructions Manual page 11

Standard device has to be subscribed again to the CT-DECT Multi WireCom – Digital Interface Base
according to the subscription procedure.
Once the subscription procedure has been successfully completed, the identity of the communication
participants is stored in the data memory of the device. The CT-DECT Standard headset stores one
CT-DECT Multi WireCom – Digital Interface Base. The CT-DECT Multi WireCom – Digital Interface
Base stores the last four successful subscribed CT-DECT Standard headsets.
Time Out
If no successful subscription between a CT-DECT Standard headset and the CT-DECT Multi WireCom
– Digital Interface Base was achieved after maximum 2 minutes, a »Time Out« occurs. The »Time Out«
is signalized by a tone sequence of 4 short deep tones in the communication headset of the CT-DECT
device, which repeats itself every 4 seconds.
After a »Time Out« all necessary CT-DECT Standard headsets have to be subscribed again to the CT-
DECT Multi WireCom – Digital Interface Base.
7.3 On-air subscription
The following example explains how to subscribe a CT-DECT Standard headset to the CT-DECT Multi
WireCom – Digital Interface Base. The subscription of a second, third, and fourth CT-DECT Standard
headset to the CT-DECT Multi WireCom – Digital Interface Base is done analogously.
a. The CT-DECT Multi WireCom – Digital Interface Base must not be connected to the ring circuit
(power supply) of the WireCom system. Plug the adapter cable (figure 1/b) into the Multi, if not yet
connected.
Make sure the CT-DECT Standard headset to be subscribed is in switched-off condition. Take the
cushion off the headset's left ear muff. The subscription button is located inside the ring of the ear
muff. Follow the recommendations of the special CeoTronics instruction manual for this headset.
b. On the CT-DECT Multi WireCom – Digital Interface Base, push at least one of the five buttons of the
pushbutton bank (figure 1/g) and keep it depressed. While keeping the button depressed, connect
the CT-DECT Multi WireCom – Digital Interface Base with the plug connector of the adapter cable to
the ring circuit of the WireCom system and after connection keep depressing the button until the sta-
tus LED (figure 1/e) lights up red. Then continue immediately with step »c«, to avoid a »Time Out«.
c. On the headset, push the subscription button and keep it depressed. While depressing it, activate
the headset with the On/Off switch/volume control (rotary control button) and keep this button de-
pressed for at least another two seconds after switch-on. Then let it go.
The on-air subscription is initiated and you hear in your headset a short high beep intermittently in
about 2-second intervals, followed after approx. 30 seconds by a high double beep. This confirms
successful completion of the subscription process.
d. After completion of the subscription process switch the headset, subscribed first, off. Pull
the jack plug of the adaptor cable off the WireCom system's ring circuit, in order to discon-
nect the CT-DECT Multi WireCom – Digital Interface Base from power supply.
7.4 After subscription
After subscription all newly subscribed CT-DECT Standard headsets must be switched off again and
the CT-DECT Multi WireCom – Digital Interface Base disconnected from the ring circuit (power supply),
before the communication system can be operated (see chapter 3).
