GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
Icare TONOVET Plus tonometer (TV011) is intended for use in the electromagnetic environment specified below.
The customer or the user of the Icare TONOVET Plus tonometer (TV011) should assure that it is such an environment.

Portable and mobile RF communications equipment should be used no closer
to any part of the Icare TONOVET Plus tonometer (TV011), 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 metres (m).

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 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 Icare TONOVET Plus tonometer (TV011) is used
exceeds the applicable RF compliance level above, the Icare TONOVET Plus tonometer (TV011) should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the Icare TONOVET Plus tonometer (TV011).
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF COMMUNICATIONS EQUIPMENT AND
ICARE TONOVET PLUS TONOMETER
Icare TONOVET Plus tonometer (TV011) is intended for use in an electromagnetic environment in which radiated RF-disturbances are controlled. The customer
or the user of the Icare TONOVET Plus tonometer (TV011) can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and Icare TONOVET Plus tonometer (TV011) as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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 propagation is affected by absorption and reflection from structures, objects and people.
TV011 is class B equipment and needs special precautions regarding EMC and needs to be installed and put into service according to EMC information provided
in Instruction for use manual.
