1.1 General safety instructions
Before using CeoTronics products read completely the appropriate operating
instructions. If in doubt, ask our technical staff.
Keep these operating instructions for later use.
If repair work of any kind needs to be done to CeoTronics products, arrange for it to
be performed only by the company CeoTronics or by a specialized workshop that is

Revision: 02/1015 DOK 1643-us 4 of 28
authorized by CeoTronics. In all other cases, our warranty and liability for the
product shall lapse.
Keep CeoTronics products out of the reach of children and any other persons who
are not familiar with the handling and operation thereof.
CeoTronics products may only be used for the specific application envisaged.
Product damage!
Do not immerse a CeoTronics product into water, if it is not expressly specified for
this purpose.
Risk of injury!
When using CeoTronics products that are equipped with connection leads ensure
that the latter do not get caught up in operational machinery or wheels!
Road traffic hazard!
Do not leave CeoTronics products lying around loose in cars, e.g. on the parcel
shelf. Stow these products in a suitable, safe place in the car so that they do not
present a danger to you or to other occupants of the car, if emergency braking is
effected.
When driving a car, do not use the radio because it may distract you from the other
traffic. Never use a CeoTronics product (communication set, insert earphone,
inductive receiver etc.) that will impair your hearing.
Risk of explosion!
CeoTronics products that are not intrinsically safe (explosion-proof) and therefore
have no special explosion-proof designation must never be operated in potentially
explosive environments (e.g. when refuelling cars, aircraft etc.). Devices that are not
explosion-proof can unintentionally trigger off explosions in such areas!

5 Product description
5.1 Description
The CT-Multi PTT Bluetooth (PTT-Push to talk) provides the possibility of cable connection to a radio
and to a cellular phone via the integrated Bluetooth interface. The necessary CT communication set
(not part of the scope of supply) is plugged into the corresponding socket.
With the CT-Multi PTT Bluetooth, most of CeoTronics communication systems with 12-pin connector
can be used on all cellular phones, supporting the Bluetooth Standard.
The CT-Multi PTT Bluetooth can be equipped with a CT-Wireless-PTT.
The CT-Multi PTT Bluetooth provides 128 bit coding.
Bluetooth devices should have a distance of maximum 40 cm from each other (could be more,
depending on the particular cell phone) and “visual contact” to ensure a secure Bluetooth connection.

Figure 2 Example Wearing method
The CT-Multi PTT Bluetooth complies with the Bluetooth specification 2.1. At some places, there exist
restrictions regarding the use of Bluetooth devices. Ask your service provider or the competent
authorities.
An AA battery or AA storage battery provides the electrical power. For radio operation, the Bluetooth
module must be in switched-on state, even if no cellular phone is used. Normally, switch-on is
controlled via radio or by keystroke.

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.
