zIf 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.
zFor safety reasons reception volumes in excess of 85 dB(A) are possible with a whole series of
CeoTronics products. However, these can be regulated by the user. 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 high volumes or noise levels wear additional ear plugs. If in doubt, ask your safety
officer or company doctor.
zWhen 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.
zDo 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.
zWhen driving a car, do not use the radio because it may distract you from the other traffic. Never use
a CeoTronics product (headset, insert earphone, induction receiver etc.) that will impair your hearing.
zCharge rechargeable batteries only with the appropriate suitable CeoTronics charger. Observe the
voltage and currency specifications, including those on the mains face (e.g. 230 V AC or 115 V AC).
Never use the charger to recharge non-rechargeable batteries.
zWhen handling rechargeable batteries comply with environmental protection regulations !
Rechargeable batteries contain toxic chemicals (e.g. cadmium). Never attempt to open a
rechargeable battery and never throw a rechargeable battery into fire. Expended (defective)
rechargeable batteries are subject to compulsory regulated waste disposal. Do not put them in the
household waste !
zEnsure that a short-circuit (risk of fire or injury) is not created across rechargeable battery terminals
or charging sockets by a short-out (bent-open paper clip, bunch of keys etc.). In such an event the
warranty shall lapse. Transport any spare rechargeable batteries in an electrically non-conducting
package in order to avoid short-circuiting the rechargeable batteries.
zKeep CeoTronics products and rechargeable batteries out of the reach of children and any other
persons who are not familiar with the handling and operation thereof.
zPackaging 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 !
zSafe operation requires clean devices. Ensure that the devices (microphones, connectors etc.) are
clean and in good condition at all times.
zCeoTronics products may only be used for the specific application envisaged.
zIf the device is to be put out of operation definitively, bring it to a local recycling plant for disposal or
send it to CeoTronics.
2. Description
2.1 General
The CT-DECT Multi is together with a CeoTronics communication headset or hand microphone or other
communication devices a transmitter/receiver unit for wireless duplex communication between a max.
of three communication parties over short distances. The range depends on the local circumstances.
Up to two standard units are allocated to a base unit. Channel selection is effected automatically.
Protection against eavesdropping and interference is ensured.
The unit is fitted with a connector for various CeoTronics communication sets which are available as an
accessory. Frequently used communication sets are described in sections 2.4...2.9. The CT-DECT
