following standards must also be observed.
Safety information
•
The SMSB121TH incorporates a low power radio transceiver. When in operation by road and receives
radio frequency energy. Operation in the vicinity of radios, televisions, telephones or elec-
tronic devices in general may cause interference. It may also be subject to interference that
may affect its performance.
•
