NOTES:
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 theoretically predicted with accuracy. An
electromagnetic site survey should be taken into consideration
to assess the
electromagnetic environment due to fixed RF transmitters. If the measured field strength
in the location where the
Vesta
Charger is used exceeds the applicable RF compliance
level above, the
Vesta
Charger should be monitored to ensure normal
operation. If an
abnormal function is observed, additional measures may be necessary, such as
relocating the Vesta Charger.
b
-
For frequencies in the range of 150 kHz to 80 MHz, the field strength should be less
than 3 V/m.
Recommended Separation Distances between Portable and Mobile
RF Communications Equipment and the Vesta Charger
Recommended separation distances between portable and mobile RF
communications equipment and the Vesta Charger
The Vesta
Charger should be used in an electromagnetic environment with limited
radiated RF noise. The customer or user of the
Vesta Charger can help prevent
electromagnetic interference by maintaining the minimum distance between portable and
mobile RF communications equipment (transmitters) and the
Vesta Charger

For transmitters with a maximum rated output power not listed above, the recommended
separation distance “d” in meters (m) can be estimated by using the equation applicable
to the frequency of the transmitter, where “P” is the maximum rated output power of the
transmitter in watts (W) specified by the transmitter manufacturer.

At 80 M
Hz and 800 MHz, the higher frequency range applies.
Note:
These guidelines may not apply to all settings. Electromagnetic propagation is
affected by absorption and reflection from buildings, objects, and people.
