Chapter 4: Operating the Device
Recommended separation distances between portable and mobile RF communications equipment and the
W15L100-PTA3-ME
The W15L100-PTA3-ME is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the W15L100-PTA3-ME can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
W15L100-PTA3-ME as recommended below, per the maximum output power of the communications equipment.

For transmitters rated a maximum output power not listed above, the recommended separation distance
d
in
meters (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) per 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.
General Safety
W15L100-PTA3-ME is a DC powered device. Use with the supplied AC adaptor. Operate
the unit on 100-240V AC only.
For plug-in equipment, the power outlet socket must be located near the equipment and
must be easily accessible.
Use a power cord that matches the voltage of the power outlet, which has been approved
and complies with the safety standard of your particular country.
The nameplate indicating operating voltage, etc. is located on the AC adaptor.
Should any solid object or liquid fall into the cabinet, unplug the unit and have it checked by
qualified personnel before operating it any further.
Unplug the unit from the wall outlet if it is not to be used for several days or more.
To disconnect the AC power cord, pull it out by grasping the plug. Never pull the cord itself.
The socket-outlet shall be installed near the equipment and shall be easily accessible.
Medical use
Please do not touch patient and this medical device at the same time.
Users must not allow SIP/ SOPs and the patient to come into contact at the same time.
Grounding reliability can only be achieved when the equipment is connected to an
equivalent receptacle marked “Hospital Only” or “Hospital Grade”.
Installation
This device can only be installed by manufacturer authorized and trained personnel.
Prevent internal heat build-up allowing adequate air circulation.
Do not place the unit on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies)
that may block the ventilation holes.
Do not install the unit near heat sources such as radiators or air ducts, or in a place subject
to direct sunlight, excessive dust, mechanical vibration or shock.
Do not place the monitor near equipment which generates magnetism, such as a
transformer or high voltage power lines.
Use suitable mounting apparatus to avoid risk of injury.
