When using portable and mobile HF telecommunications units, in-
cluding their accessories, there must be a distance of at least
30 cm between them and the unit and its cords.
WARNING
Use of non-approved internal cables by Technical Service
This can result in the increased emission of electromagnetic waves or
reduce the immunity of the unit.
Risk of injury to the patient.
The unit may fail or not perform properly.
Technical Service may only use the internal cables that are listed
in the service manual for the unit.
Guidance and manufacturer's declaration - electromagnetic emissions
The unit is intended for use in the electromagnetic environment specified below. The customer or the user of the unit should
ensure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment - guidance
HF emissions CISPR 11 Group 1 The unit only uses HF energy for its internal function.
HF emissions CISPR 11 Class A The properties of this unit in terms of its emissions
mean it can only be used in medical facilities that are
connected to supply systems specifically provided for
that purpose (usually supplied via isolating transform
-
ers). For domestic use (for which class B is usually
required as per CISPR
11), this unit may not offer ade-
quate protection against radio services. The user may
need to take corrective measures such as relocating or
reorienting the unit.
