TERMINALS HT910 E Terminal User Manual Revision 1 3 Important information This technical description contains important information for start up and use of the HT910 E Terminal Read it carefully before you start working with the HT910 E Terminal The warranty will be void should damage occur due to non compliance with these instructions for use We cannot accept any responsibility for consequential loss We cannot be held responsible for material loss or personal injury that is due to incompetent use or non compliance with the safety instructions The warranty will be void in such circumstances The HT910 E Terminal contains highly integrated components which can be damaged by electrostatic discharge if the user would open the housing CEP preserves the right to change the included information without notice and doesn t take responsibility for errors in the document and or missing information Therefore only touch the HT910 E Terminal on the housing or connectors and avoid touching the components on the board Safety Instructions When using products which are exposed to electric voltage the valid regulations have to be observed Before opening of a device always pull the mains adapter or make sure that the device is disconnected from the power supply You should only use tools on components modules or devices if they are disconnected from the power supply and the electric charge which may still be stor
4. 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 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 18 4 1 TERMINALS Installation of the modem This chapter gives you advice and helpful hints on how to integra
