Recommended separation distances between portable and mobile RF communications equipment
The LMD-X310MT/X550MT is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the LMD-X310MT/X550MT can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the LMD-X310MT/X550MT as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated a maximum output power not listed above, the recommended separation distance
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where
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
When you dispose of the unit or accessories, you must
obey the laws in the relative area or country and the
regulations in the relative hospital regarding
environmental pollution.
WARNING
The apparatus shall not be exposed to dripping or
splashing. No objects filled with liquids, such as vases,
shall be placed on the apparatus.
WARNING
To prevent injury, if mounting the unit using a mounting
arm, wall fixture, or other mounting device prepared by
the customer, mount the unit securely as described in the
instruction manual provided with the mounting device.
When fixing the unit, use more than 4 of the supplied
screws for the VESA mount or specified screws.
Fasten the screws to the hole positions firmly and
symmetrically to the upper and lower, left and right
positions towards the center of the monitor.
Check beforehand that the mounting device used has
sufficient strength to support the added weight of the unit.
Check yearly that the mounting device is securely
attached.
