surroundings. The following examples illustrate
conditions that may reduce the possible receiving
range or cause interference with reception.
• Inside a building with walls containing steel
beams.
• Area with many steel file cabinets, etc.
• Area with many electrical appliances capable
of generating electromagnetic noise.
• Transmitter is placed on a metal instrument.
• Area facing a roadway.
• Noise or interfering signals exist in the
surroundings due to radio transceivers in
trucks, etc.
• Noise or interfering signals exist in the
surroundings owing to wireless
communication systems installed along
