WARNING
•
The BT-410F and BT-410A should not be used adjacent to or stacked with other
equipment. If adjacent or stacked use is necessary, the device should be observed to verify
normal operation in the configuration in which it will be used.
•
Portable RF communications equipment (including peripherals such as antenna cables
and external antennas) should be used no closer than 30 cm (12 inches) to any part of the
BT-410F and BT-410A, including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
•
Use of adapter other than those specified or provided by the manufacturer of this
equipment could results in increased electromagnetic emissions or decreased
electromagnetic immunity of this equipment and result in improper operation.
7.2 Electromagnetic immunity
