T
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the product is used
exceeds the applicable RF compliance level above, the product should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m.
Information.
Disconnecting the bed from the power supply switches off the VariZone module.
After connecting the power supply, the VariZone module must be switched on again and
configured.
