5.3 CT-Multi-PTT Bluetooth with CT-ClipCom Digital
The CT-Multi-PTT Bluetooth is also available with integrated CT-ClipCom Digital technology and firmly
attached communication set.
The following two (2) system configurations are available:
CT-ClipCom Digital EarMike consisting of an ear microphone and an additional speaker
You hear radio messages and the ringing tone of the cellular phone on both sides. If a PTT transmit
button is activated or a conversation takes place via cellular phone, the RH ear microphone is switched
over from speaker to microphone operation. This deactivates the reception of exterior noise on that ear
microphone.
CT-ClipCom Digital BoomMike consisting of one earphone with boom microphone and an additional
speaker.
While activating a transmit button, the reception of exterior noise continues being active on both sides.
The earmike is an electroacoustic transducer working as both, microphone (transmitting) and earphone
(receiving), and is worn inside the ear with earplugs or personalized ear molds. Regarding personalized
ear molds, follow the instruction manual Dok1463.

7.14 CT-Wireless-PTT (optional)
For interference-free operation of the CT-Wireless-PTT receiver in the CT-Multi
PTT Bluetooth, take care that the CT-Multi PTT Bluetooth is not located in close
proximity to the transmitting antenna of a radio or cellular phone. Heterodyning the
CT-Wireless-PTT radio signal by the comparatively strong transmit signal of a
radio or cellular phone can compromise the sensitivity of the CT-Wireless-PTT
receiver in the near field of the transmit antenna. This could interrupt the radio
transmission from the sending to the receiving PTT.
The CT-Wireless-PTT and the Bluetooth key of the CT-Multi PTT Bluetooth have equal function. The
CT-Wireless-PTT necessarily requires subscription to the CT-Multi PTT Bluetooth. A battery supplies
electric power to the CT-Wireless-PTT. For safety reasons, continuous keying of the CT-Wireless-PTT
is limited to 30 seconds.

7.18 Switch-on and operation
Risk of hearing impairment
For safety reasons reception volumes in excess of 85 dB(A) are possible with
a whole series of CeoTronics products. However, the user can regulate the
volumes. After switching on the communication system, set the reception
volume to approx. 1/2 the available loudness volume and then test the audible
volume, e.g. by opening the squelch on the radio set.
Do not set the volume any higher than is necessary. A very high volume
setting can lead to damaged hearing, particularly if it is continuous. For higher
volumes or noise levels wear additional earplugs. If in doubt, ask your safety
officer or company doctor.
Turn the radio on, observing the manufacturer’s instruction manual. When turning the CT-MultiPTT
Bluetooth on, the LED in the Bluetooth button lights up green for about four (4) seconds (battery test).
After that, the battery / storage battery status is displayed. Should the LED not glow continuous green
during the first seconds, then the battery or storage battery is flat and requires replacement. Operation
is not possible.
At turn-on, the volume of the CT-MultiPTT is always set to medium. Now you can hear the incoming
radio messages in your communication set.
7.18.1 Communication via radio
The PTT serves the purpose of switching the radio between transmitting and receiving. For transmitting,
you must press the PTT button while speaking. If the communication set is equipped with a PTT button,
then this one and the PTT of the CT-MultiPTT Bluetooth have equal function.
If there exists an active telephone communication, voice to telephone is deactivated while transmitting.
Hearing the telephone is possible. When you let the button go, you return to standby/receiving mode.
Adjust the volume
Adjust the desired reception volume using the “Volume-up” and Volume-down” keys. It is not possible,
to completely down-regulate the volume. A minimum level persists. In a telephone conversation via
Bluetooth (cellular phone), adjustment of the reception volume takes effect on the Bluetooth connection.
7.18.2 Communication via cellular phone
Switch on the cellular phone and set it to mute. (Observe the instruction manual of your cellular phone)
Now, you are ready for communication via radio or cellular phone.
Switch on the Bluetooth module
You are able to communicate via cellular phone, even if on the CT-Multi PTT Bluetooth the radio is
neither active nor connected. Press simultaneously both, the Bluetooth and “Volume-up” keys, until you
hear an ascending three-tone sequence in the CT communication set. When switching on the CT-
MultiPTT Bluetooth the LED in the Bluetooth button lights up green for about four (4) seconds (battery
test). Should the LED not glow continuous green during the first seconds, then the battery or storage
battery is flat and needs replacement. Operation is not possible.
Afterwards, the LED indicates the battery / storage battery status for the first 15 seconds.
Green, continuous - battery fully charged
Green, flashing - battery at half charge
Red, flashing - battery almost flat, approx. 30 minutes remaining
LED off - device does not switch on; battery/storage battery is flat.
After 15 seconds, the LED goes out.
Revision: 02/1015 DOK 1643-us 25 of 28
Should the radio be turned off (battery change) while the Bluetooth module is on,
you hear in the communication set for 30 seconds an acoustic warning signal in
two (2) second intervals. During these 30 seconds press a key or turn the radio on,
to ensure the Bluetooth module continues in switched-on condition. This way it is
possible to keep up telephone standby.
Switch off the Bluetooth module
Turning the radio off, switches the Bluetooth module off as well, with a delay of 30 seconds. However,
you are also able to disconnect the entire system, independently from the radio.
Press simultaneously both, the Bluetooth and Volume-up keys, for about 3 seconds until you hear a
descending three-tone sequence in the communication set which confirms the switch-off. The LED
in the Bluetooth key does not glow anymore. Let the keys go.
7.19 End of operation
To end the operation, turn the radio off.
In some radios, the accessory interface continues energized, even after turning the
radio off. In such a case switch the key off manually, or disconnect the CTMultiPTT
Bluetooth plug from the radio adapter. Otherwise, it is possible that the CT-
MultiPTT Bluetooth storage battery is discharging.

8.1 Cleaning
Product damage!
Pay attention that no humidity could penetrate into the device during cleaning.
Do not use solvents (e.g. benzene, alcohol, etc.) for cleaning!
Safe operation requires clean devices. Ensure that the devices (microphones,
connectors etc.) are clean and in good condition at all times.
Remove loose dust with a soft brush. Clean the outside of components, if necessary, with an
appropriate clean cloth, only lightly moistened with clear water, and then rub it down thoroughly. If
heavily soiled, a few drops of rinsing agent may be added. Clean the connector pins with a commercial
cleaning agent.
