7.5 Pairing
Pairing of only one Bluetooth device at a time is
possible with a CT-Multi PTT Bluetooth. When
repeating the pairing, the existing connection is
lost.
1. Switch the CT-Multi PTT Bluetooth off.
2. Activate the Bluetooth function of your
Bluetooth device (cellular phone or digital
radio).
3. Press simultaneously for about 8 seconds the
Bluetooth and volume-up keys on the CT-
Multi PTT Bluetooth until you hear a
descending
five-tone sequence
(approx. 8 seconds). In between, you hear an
ascending
three-tone sequence,
confirming the switch-on process.
4. Let the keys go. You hear a beep in 2-second
intervals. The CT-Multi PTT Bluetooth is in
search mode.

5. Put the other Bluetooth device (cellular phone or digital radio) into Bluetooth search mode. For
it, follow the operating instruction of the device manufacturer.
6. When the Bluetooth device to be paired announces a search result with the name of the
CT-Multi PTT Bluetooth, confirm the pairing by entering the following PIN number in the
device: 83787432
You find the name of the CT-Multi PTT Bluetooth on the label pasted on the cable (Figure 3).
7. After successful pairing, you hear an ascending
five-tone sequence in the CT
communication set.
Once paired, both devices re-establish the Bluetooth connection, even after interruptions, within
the possible Bluetooth range.
