Introduction
Always observe the following precautions to prevent operation failures, malfunctions, and adverse effects on
performance and equipment.
1. Installation and Storage Environment
Do not use or store the Product 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 operating humidity range
• Locations subject to direct vibration or shock outside the specified ranges
• Locations subject to spray of water, oil, or chemicals
2. Environment
• This Product uses a frequency band of 13.56 MHz to communicate with ID Tags. Some motors,
inverters, switching power supplies, and other devices generate electrical noise that will affect com-
munications with the ID Tags. If any of these devices are located in the vicinity of the Product, they
may affect communications with ID Tags, and may possibly damage the ID Tags. Prior to using the
Product in the vicinity of any of these devices, perform a test to determine whether the Product can
be used under the resulting influence.
• Observe the following precautions to minimize the effects of normal noise.
(1) Ground all metal objects in the vicinity of the Product to 100 Ω or less.
(2) Do not use the Product near high-voltage or high-current lines.
• Connectors are not waterproof. Do not use the Product where mists are present.
• Do not use chemicals that would affect the materials used in the product.
• Be sure the USB connector is properly inserted when using the USB port on the V680-CHUD.
• Always use the specified AC Adaptor (V600-A22) when using the V680-CH1D.
3. Host Communications
Always confirm that the Product has been started before attempting to communicate with it from the
host. Also, when the Product is started, unstable signals may be output from the host interface. When
starting operation, clear the reception buffers in the host or take other suitable countermeasures.
4. Cleaning
• Do not clean the product with thinners, benzene, or other organic solvents. These will dissolve the
resin parts and coating on the case.
