Introduction
Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects on
performance and equipment.
1. Installation Environment
Do not use the Products in the following locations.
• Locations exposed to corrosive gases, dust, metallic powder, or salts
• Locations not within the specified operating temperature range
• Locations subject to rapid changes in temperature or condensation
• Locations not within the specified humidity range
• Locations subject to direct vibration or shock outside the specified ranges
• Locations subject to spray of water, oil, or chemicals
2. Installation
• The Products communicate with RF Tags using the 13.56-MHz frequency band. Some motors,
inverters, and switching power supplies generate noise that can affect communications with the RF
Tags and cause errors. If such devices are located near the RF Tags, always test operation in
advance to confirm whether the system will be affected.
• Observe the following precautions to minimize the effects of normal noise.
(1)Ground all metal objects in the vicinity of the Products to 100 or less.
(2)Do not use the Products near high-voltage or high-current lines.
• The communications range is adversely affected if there is any metal material around the RF Tag.
• Transmission will not be possible if the front and back panels are mistakenly reversed and the Unit is
mounted to a metallic surface.

• The maximum communications range can be obtained when the Antenna faces the RF tag directly.
When the RF tag is installed at a tilt, the communications range is reduced. Consider the effect of the
RF tag at tilt when installing the RF Tag.
• Provide the mounting distances between plural RF tags to prevent them from malfunctions due to
mutual interference.
• If the central axis of an antenna and RF tag shifts, a communications range will fall.
