EXCEL V OPERATOR MANUAL
D1025, REV H, 10/17
Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The Excel V is intended for use in the electromagnetic environment specified below. The customer or the user
of the Excel V should ensure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Excel V, including its cables,
than the recommended separation
distance calculated from 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
and d is the recommended separation
distance in meters (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:
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 absorp-
tion 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 theo-
retically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electro-
magnetic site survey should be considered,. If the measured field strength in the location in which the Excel V
is used exceeds the applicable RF compliance level above, the Excel V should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the Excel V.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
