The LH-150PC is intended for use in the electromagnetic environment specified below. The customer or the user of the LH-150PC
should assure that it is used in such an environment.
The LH-150PC uses RF energy only for its internal function. Therefore, its RF emissions are
very low and are not likely to cause any interference in nearby electronic equipment.
The LH-150PC is suitable for use in all establishments, including domestic establishments
and those directly connected to the public low-voltage power supply network that supplies
buildings used for domestic purposes.
The LH-150PC is intended for use in the electromagnetic environment specified below. The customer or the user of the LH-150PC
should assure that it is used in such an environment.
Mains power quality should be that of a typical
commercial or hospital environment, if the user of the
LH-150PC requires continued operation during power
mains interruptions, it is recommended that the LH-
150PC be powered from an uninterruptible power
supply.

should assure that it is used in such an environment.
Portable and mobile RF communications equipment
should be used no closet to any part of the LH-150PC,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the LH-150PC is used exceeds the applicable RF complience level above, the LH-150PC should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary such as reorlenting or
relocating the LH-150PC.
