RF emissions CISPR 11
Group 1
The Generator Model 825DP uses RF energy only for its internal function. Therefore, its RF emissions
are very low and are not likely to cause any interference in nearby electronic equipment.
RF emissions CISPR 11
Class A
The Generator Model 825DP is suitable for use in all establishments other than domestic and those
directly connected to the public low-voltage power supply network that supplies buildings used for
domestic purposes.

interruptions, it is recommended that the Generator Model
825DP be powered from an uninterruptible power supply or a
battery.

Portable and mobile RF communications equipment should be used no closer
to any part of the Generator Model 825DP, including cables, than the
recommended separation distance calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
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 meters (m). Field strengths from fixed RF transmitters,
as determined by an electromagnetic site survey

, 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:
NOTE 1 At 80 MHz and 800 MHz, 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 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 Model 825DP is used exceeds the applicable RF compliance level above, the Model 825DP should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Model 825DP.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
