4. Technical explanation regarding EMD (Electromagnetic Disturbance)
The bed requires special safety precautions regarding EMC to be observed. Install, operate, and use the
bed according to the information provided below.
The bed is intended for use in an electromagnetic environment specified according to “Electromagnetic
interference.” Using the bed in an unintended environment may result in the occurrence of the following
problems.
• The function for supporting the patient’s body weight may not be maintained.
• The emergency head-down function may not be maintained.

The bed is intended for use in doctor’s offices, clinics, exclusive medical facilities, independent surgery
centers, multiple treatment facilities, hospitals (except near high-frequency surgical equipment, and
outside RF shielded rooms for magnetic resonance images). The customers or users of the bed must
ensure that the bed is always used in this environment.
Due to its emission characteristics, the bed is suitable for use in hospitals. If used in a home environment,
this device may not offer sufficient protection against radio frequency communication services. It may be
necessary for the user to take relaxation measures such as re-arranging or changing the direction of the
device.
●
If accessory, transducers, or cables other than those specified and sold by
the manufacturers of the bed are used as replacement parts for internal
components, it may result in an increase in emission or a decline in
immunity of the bed.
●
Use portable RF communication devices (including antenna cables and
peripheral devices such as external antennas) at a distance of at least 30 cm
from all parts of the bed. Using the RF communication devices within a
distance of 30 cm may cause a decline in the performance of the bed.
●
The bed cannot be used adjacent to another device or in a stacked state. If
the bed must be used adjacent to another device or in a stacked state, make
sure the bed operates appropriately at the location of use.
Guidance and manufacturer’s declaration — electromagnetic emissions
The bed is intended for use in the electromagnetic environments specified below. The customer or the
user of the bed must use it in an environment specified here.

RF emissions
CISPR 11
Group 1
The bed uses RF energy only for its internal functions.
Therefore, its RF emissions are low and are not likely to
cause any interference with nearby electronic equipment.
