 The HT63-E Terminal must not be installed or located where the surface temperature of the plastic

case may exceed 85°C.

 All cables connected to the HT63-E 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 HT63-E 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 HT63-E 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.

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.
