For trouble-free operation of the receivers of the CT-WirelessPTT, make sure that
the receiver housing is not in the immediate vicinity of the transmitting antenna of
a radio or mobile phone. If the radio signal of the CT-WirelessPTT is overlaid by
the comparatively strong transmission signal of a radio or mobile phone, this can
impair the sensitivity of the CT-WirelessPTT in the near field of the transmitting
antenna. This can interrupt radio transmission from the PTT transmitter to the
PTT receiver!

Operation Instructions
A CT-WirelessPTT is a PTT (Push to Talk) button/transmitter for activation or control of special CeoTronics products which you
can covered keep in hand and use.
Possible CeoTronics products are for example:
In these products is a receiver for different CT-WirelessPTT installed. The CT-WirelessPTT must be paired with the receiver in
the CeoTronics products. The pairing, deleting and some functions of the CT-WirelessPTT can be different at the different
CeoTronics products. These procedures are described in the special user manuals of the CeoTronics products.
Operation Range: approximately 5 m Frequency: 916,5 MHz Modulation: FSK
English - USA
Revision: 01/1014 DOK 1652-us

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 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.
Impairment of flight operation!
When on board an airplane always keep a transmitter/receiver switched off. Operation of the
transmitter/receiver could affect the safety of the airplane and it is therefore prohibited. Never operate
electronic devices on board an airplane without the express approval of an authorized member of the
cabin crew.
Impairment of radio transmission!
Transmit only when it is necessary. Unnecessarily occupying a channel can prevent the transmission
of vitally important information.
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!
Adverse effect on cardiac pacemakers
If you are a cardiac pacemaker carrier, before operating a transmitter/receiver ask the manufacturer of
your cardiac pacemaker for information about any impairment that might be caused due to high
frequencies.
Warning - and Safety instructions
Notice for the use of the device for prevention of personal injury or property damage the national safety and accident
prevention regulations and the following warning and safety instructions in this instruction manual.
Important Notes for operation of the Transmitter in the USA and Canada
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment
This device complies with Part 15 of the FCC Rules and Industry Canada licence-exempt RSS
standard(s).
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired
operation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts
de licence. L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible
d'en compromettre le fonctionnement.
General safety instructions
Revision: 01/1014 DOK 1652-us

Inspect the goods immediately upon receipt for completeness and possible transport damages!
Notify transport damages immediately to the forwarder and CeoTronics AG!
Danger of ingestion and choking!
Packaging materials, e.g. filling materials and plastic bags are not toys and have to be kept out of the reach
of children. There is a risk of children ingesting them and choking!
Dispose of packaging material in an environmentally responsible way!
The LED illuminate by pressing of C1.
The LED illuminates during sending and can show the channel
assignment of the large button (C1/C2). For check press S (with
an appropriate “blunt” tool) until the LED illuminates.
1 x illuminate – C1
2 x illuminate – C2
For change the channel press S until the LED illuminate.
– then press in the time of 3 seconds the button again. The
assignment is displayed.
In order to prevent the LED lights up when you press the buttons,
press the S button for more than 5 seconds until the LED lights
up. For switch ON press S again for more than 5 seconds until
the LED lights. During the pressing is displayed first the channel
assignment of the large button (C1/C2).
Receipt of goods
Transport and storage
Make sure the environmental conditions specified in the technical data sheet are met and complied with in transit, at the
storage location and site of operation! Take appropriate measures to avoid vibration, impacts and drops! Choose adecuate
packaging when dispatching the device. Store the device after cleaning it in an appropriate dry place at constant ambient
conditions. Avoid extreme temperature fluctuation!
