Guidance and manufacturer's declaration – electromagnetic immunity
The Multi Pad is intended for use in the electromagnetic environment specified below. The customer or the user of the Multi Pad should assure
that it is used in such an environment.

a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobiles 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
Multi Pad is used exceeds the applicable RF compliance level above, the Multi Pad should be observed to verity normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the Multi Pad.
b
Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the Multi Pad
The Multi Pad is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the Multi Pad can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the product as recommended below, according to the maximum output power of the
communications equipment.
