Guidance and manufacturers declaration ʹ electromagnetic immunity
The Tobii Dynavox I-Series+ device is intended for use in the electromagnetic environment specified below. The customer of
the user of the Tobii Dynavox I-Series+ device should assure that it is used in such an environment.

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
reflected from structures, objects and people.
i. 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 Tobii Dynavox I-Series+
device is used exceeds the applicable RF compliance level above, the Tobii Dynavox I-Series+ device should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Tobii Dynavox I-Series+ device.
ii. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF (Radio Frequency) communications equipment and
the Tobii Dynavox I-Series+ device.
The Tobii Dynavox I-Series+ device is intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Tobii Dynavox I-Series+ device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communication equipment
(transmitters) and the Tobii Dynavox I-Series+ device as recommended below, according to the maximum output power of
the communications equipment.
