Sony LMD-3251MT Manual page 20

Recommended separation distances between portable and mobile RF communications equipment and the LMD-
3251MT
The LMD-3251MT is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the LMD-3251MT can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the LMD-3251MT as recommended below, according
to the maximum output power of the communications equipment.
Rated maximum output power of transmitter
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) according to 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.
CAUTION
• For safety, do not connect the connector for peripheral
device wiring that might have excessive voltage to the
following ports.
: SERIAL REMOTE connector
: PARALLEL REMOTE connector
Follow the instructions for the above ports.
• These connectors are designed to allow direct contact
with conductive circuits. Weak voltage may be present
because of a failure in this unit. To prevent patients
from touching these connectors accidentally, attach
the connector covers when the connectors are not
being used to connect to other devices.
• When you connect the LAN cable of the unit to
peripheral device, use a shielded-type cable to prevent
malfunction due to radiation noise.
WARNING
Using this unit for medical purposes
This equipment's connectors are not isolated.
Do not connect any device other than one which
conforms to IEC 60601-1.
When an information technology device or AV device
that uses an alternating current is connected, current
leakage may result in an electric shock to the patient or
operator.
If use of such a device is unavoidable, isolate its power
supply by connecting an isolation transformer, or by
connecting an isolator between the connecting cables.
After implementing these measures, confirm that the
reduced risk now conforms to IEC 60601-1.
