All cables connected to the CT63 Terminal must be secured or clamped, immediately adjacent to the
modem's connectors, to provide strain relief and to avoid transmitting excessive vibration to the modem
in the installation.
Ensure the cables, supplying power, audio headset, and input cable to the CT63 Terminal, does not exceed
3 metres.
To protect power supply cables and meet the fire safety requirements when the unit is powered from a
battery or a high current supply, connect a fast 1.25A fuse in line with the positive supply.
Do not connect any incompatible component or product to the CT63 Terminal.
CEP AG may refuse warranty claims where evidence of product misuse is found.
4.3 SIM card precautions
Before handling the SIM card in your application, ensure that you are not charged with static electricity.
Use proper precautions to avoid electrostatic discharges.
When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card holder.
Caution! Do not touch these connectors! If you do, you may release an electrical discharge that could
damage the modem or the SIM card.
When designing your application, the SIM card's accessibility should be taken into account. We always
recommend that you have the SIM card protected by a PIN code. This will ensure that the SIM card
cannot be used by an unauthorized person.
4.4 Antenna precautions
If the antenna is to be mounted outside, consider the risk of lightning. Follow the instructions provided
by the antenna manufacturer.
Never connect more than one modem to a single antenna. The modem can be damaged by radio
frequency energy from the transmitter of another modem.
Like any mobile station, the antenna of the modem emits radio frequency energy. To avoid EMI
(electromagnetic interference), you must determine whether the application itself, or equipment in the
application's proximity, needs further protection against radio emission and the disturbances it might
cause. Protection is secured either by shielding the surrounding electronics or by moving the antenna
away from the electronics and the external signals cable.
The modem and antenna may be damaged if either come into contact with ground potentials other than
the one in your application. Beware, ground potential are not always what they appear to be.
