The use of accessories, transducers and cables other than those specified
or provided by the manufacturer of this equipment could result in increased
electromagnetic emissions or decreased electromagnetic immunity of this
equipment and result in improper operation. WARNING: 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 W5907, including cables specified by the manufacturer.
Otherwise, degradation of the performance of this equipment could result.”
WARNING:
If the use location is near (e.g. less than 1.5 km from) AM, FM
or TV broadcast antennas, before using this equipment, it should be
observed to verify that it is operating normally to assure that the equipment
remains safe with regard to electromagnetic disturbances throughout the
expected service life.
When the AC input voltage is interrupted, the equipment will stop battery
charging and if the power supply restored, it could be recovered
automatically, this degradation could be accepted because it will not lead
to unacceptable risks and it will not result in the loss of basic safety or
essential performance.
