• 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 C2, 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.
During all immunity tests, a digital tachometer was used to monitor the rotating speed of wheel and a clamp meter
was used to monitor the output current of battery charger to verify the performance of EUT.
