ATTENTION: The SATEL Company recommends that performance of the GSM LT-1
communication module be regularly tested. An efficient GSM module, which interacts
with the security system, greatly increases the chance of successful transmission of
alarm information. However, for reasons beyond the Manufacturer's control, it cannot
give 100% guarantees message delivery.
