z When 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.
z Transmit only when it is necessary. Unnecessarily occupying a channel can prevent the transmis-
sion of vitally important information.
z Charge 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.
z When handling rechargeable batteries comply with environmental protection regulations! Never
attempt to open a rechargeable battery and never throw a rechargeable battery into fire. Ex-
pended (defective) rechargeable batteries are subject to compulsory regulated waste
disposal. Do not put them in the household waste!
z Ensure that a short-circuit (risk of fire or injury) is not created across rechargeable battery termi-
nals 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.
z 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!
z Safe operation requires clean devices. Ensure that the devices (microphones, connectors etc.)
are clean and in good condition at all times.
z CeoTronics products may only be used for the specific application envisaged.
z Should equipment, supplied by CeoTronics, be definitely put out of service you may return it to
CeoTronics. We ensure recycling and/or disposal of outdated equipment in compliance with
the applicable environment protection law.
z Keep these operating instructions for later use.
2. Description
2.1 Purpose
The CT-DECT Case (see Fig. on the front page) is part of a duplex communication system over short
distances for four or eight mobile participants with CT-DECT Multi Standard (PP). The communication
between the mobile communication participants is wireless. The CT-DECT Case can be furthermore
equipped with a GSM-phone and a two-way radio. The mobile participants can then communicate with
the GSM network and an external two-way radio. The CT-DECT Case is equipped with a socket with
audio output for accessory.
The range between the CT-DECT devices (base/FP and standard/PP) depends on the local circum-
stances. The longest range is reached at eye contact in a free area. Surrounding conditions as moun-
tains, buildings, trees, weather conditions, obstacles (especially the ones containing metal) and body
damping especially with body worn systems may reduce transmitting distance.
