Guidance and manufacturer’s declaration – electromagnetic immunity - Part II
The TONO-PEN VET is intended for use in the electromagnetic environment specied below. The customer or the
user of the TONO-PEN VETshould assure that it is used in such an environment.

Portable and mobile RF communications equipment
should be used no closer to any part of the TONO-
PEN, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 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 meters (m). Field strengths from xed RF
transmitters, as determined by an electromagnetic site surveys, should be less than the compliance level in each
frequency range.
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 reection from structures, objects and people
For transmitter Field strengths from xed 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 xed RF transmitters,
an electromagnetic site survey should be considered. If the measured eld strength in the location in which
the TONO-PEN VET is used exceeds the applicable RF compliance level above, the TONO-PEN VET should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the TONO-PEN VET.
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
