Floors should be wood, concrete or ceramic tile. If floors are
covered with synthetic material, the relative humidity should
be at least 30%.

Varios560 / Varios560LUX requires continued operation
during power mains interruptions, it is recommended that the
Varios560 / Varios560LUX be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial or

Guidance and manufacturer's declaration - electromagnetic immunity
The Varios560 / Varios560LUX is intended for use in the electromagnetic environment specified below. The customer or the user of the Varios560 / Varios560LUX
should assure that it is used in such an environment.
NOTE 1
At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
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 Varios560 / Varios560LUX is used exceeds the
applicable RF compliance level above, the Varios560 / Varios560LUX should be observed to verity normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Varios560 / Varios560LUX.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.

The Varios560 / Varios560LUX is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the Varios560 / Varios560LUX can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Varios560 / Varios560LUX as recommended below, according to the maximum output power of the communications equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation
applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
