In such areas, the cellular modem must be turned off. Otherwise the cellular modem can transmit
signals that may interfere with nearby equipment that is susceptible to radio interference.
WARNING!
Communication disruption hazard – risk of serious personal injury, equipment damage, or data loss.
Wireless communications are susceptible to disruptions that may result in the delay, corruption or loss
of data. While cellular disruptions are uncommon when using a Siemens cellular modem, avoid using
the cellular modem in applications where a communication failure could result in damage to equipment
or personal injury to persons in the area. Siemens accepts no responsibility for any damages that may
result due to wireless disruptions.
NOTE
The cellular modems feature 50 Ω SMA antenna connectors on the front plate of each module.
The HSPA option is available for use on various GSM-based networks. This option supports GSM,
GPRS, EDGE, UMTS and WCDMA/HSDPA/HSUPA. The Main antenna and Receive Diversity antenna
connections are made to the 50 Ω SMA connectors.
NOTE
If two or more antennas are to be installed, the antennas must be separated by a minimum distance of
20 cm (7.9 in).
IMPORTANT!
If the device is intended for use in a portable device, separate approval is required to satisfy the SAR
requirements of FCC Part 2.1093 and IC RSS-102.
