LZ T 123 7605 P1C
provide strain relief and to avoid transmitting excessive vibration to the
Control Terminal in the installation.
• Ensure the d.c. cable, supplying power to the Control Terminal, does
not exceed 3 metres. For longer distances please contact Sony Ericsson
Service and Support.
• 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 1.5A fuse in line with the positive supply. An appropiate
fuse should be used see section “Power Supply”, page 45
• Do not connect any incompatible component or product to the Control
Terminal.
Note! Sony Ericsson may refuse warranty claims where evidence of product
misuse is found.
9.3 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 Control Terminal 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.
9.4 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 Control Terminal to a single antenna. The
Control Terminal can be damaged by radio frequency energy from the
transmitter of another Control Terminal.
• Like any mobile station, the antenna of the Control Terminal 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.
