FIBROSCAN 502 TOUCH USER MANUAL [3
. ELECTROMAGNETIC IMMUNITY (2)
The FibroScan 502 TOUCH is designed for use in the electromagnetic environment defined
below. The customer or the user of the FibroScan 502 TOUCH must ensure that it is used in
this type of environment.
60601
Immunity test | IEC Compliance Electromagnetic Environment - Directives |
test level
Portable and cellular RF communication
equipment must be kept far away from the
FibroScan device 502 TOUCH (including its
cables), at a distance greater than the
recommended distance calculated using the |
equation applicable to the emitter frequency.

The strength of EM fields for fixed emitters, as
determined by a study. 2The electromagnetic
range of the site must be within the compliance
level reguired in each freguency band. 3 |
Interference may occur in the vicinity of devices
bearing the following symbol:

NOTE 1: At 80 MHz and 800 MHz, the higher frequency band is applicable.
NOTE 2: These recommendations may not be applicable in all cases. Electromagnetic
propagation is affected by absorption and reflection caused by structures, objects and
individuals.
NOTE 3: The use of cables and/or accessories not specified in the User Manual may reduce
the device's immunity.
2. The strength of EM fields for fixed emitters such as commercial AM/FM radio broadcasting services,
television, cellular telephone services, radio detection, air traffic control, radio paging receivers and GSM
services cannot be accurately predicted. To assess the EM environment caused by fixed emitters, a site EM
study must be conducted. If the field strength measured at the location where the FibroScan device
502 TOUCH is used exceeds the compliance levels mentioned above, correct operation of the FibroScan
device 502 TOUCH must be checked. If abnormal performance is observed, additional measurements may
be required after, for example reorienting or moving the FibroScan 502 TOUCH.
3. In the frequency range 150 kHz — 80 MHz, field strengths should ideally be lower than 3 V/m.
