Floors should be wood, concrete,
or ceramic tile. If floors are covered
with synthetic material, the
relative humidity should be kept
at levels to reduce electrostatic
charge to suitable levels.
Mains power quality should be
that of a typical commercial
or hospital environment.
Equipment which emits high
levels of power line magnetic
fields (in excess of 30A/m) should
be kept at a distance to reduce
the likelihood of interference.
If user requires continued
operation during power mains
interruptions, ensure that batteries
are installed and charged.
Ensure that battery life exceeds
longest anticipated power
outages or provide an additional
uninterruptible power source.

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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance
for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propogation
is aected by absorption and reflection from structures, objects, and people.
This equipment is intended for use in the electromagnetic environment
specified below. The customer or the user of this equipment
should assure that it is used in such an environment.

Portable and mobile RF communications
equipment (including cables) should be
used no closer to any part of the equipment
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter as below.
Recommended sparation distance:
d=1.2 √P
d=1.2 √P 80 MHz to 800 MHz
d=2.3 √P 800 MHz to 2.7 GHz
Where P is the maximum output
power rating of the transmitter in
watts (W) according to the transmitter
manufacturer and d is the recommended
separation distance in metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic
site survey a, should be less than the
compliance level in each frequency range b.
Interference may occur in the
vicinity of equipment marked
with the following symbol:

The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz
to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones 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 mea-
sured field strength in the location in which the equipment is used exceeds the applicable
RF compliance level above, the equipment should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorient-
ing or relocating the equipment.
