Locations where the Reader/Writer is exposed to dust, corrosive gas, saline, or flammable gas.

Locations where the Reader/Writer is exposed to direct heat.

Locations subject to condensation due to high humidity.

Locations subject to vibration or impact that exceed the limits outlined in the specifications.

Locations where the device may be exposed to water, oil, or chemical agents. (This applies to the models other than waterproof types.)

Outdoor

Be sure to tighten the devices screws securely.

zFailure to do so may result in personal injury or device damage.

Cables with screw attachments must be secured before use.

zFailure to do so may damage the device.

Use the spcified-size cables.

zFailure to do so may result in electric shock or fire.

To avoid interferences with other systems, adhere to the following items and check them before using the product.

zThe product uses a publicly available ISM frequency band of 13.56MHz to communicate with Tags. Some transceivers, motors, monitoring devices, power supplies (power supply ICs), and other similar RFID systems may generate noise, which cause radio interference and may affect communication with Tags. If the product is required in the vicinity of these items, check for any interferences prior to use.

zOn the contrary, the system itself may affect radio station transmissions or medical devices. Be cautious when using the system in the environments where such effects might occur.

zTo minimize noise effects, adhere to the following:

Establish a Class D grounding (former Class 3 grounding) for metal objects placed in the vicinity of the system.

Keep cables away from those with high voltages or heavy currents.

Do not allow the device or cables to be exposed to water.

zDoing so may result in electric shock, fire or failure of non-waterproof devices or cables.

If the device fails or is exposed to water (non-waterproof devices or parts), or an unusual smell, smoke, or sparks are detected, immediately refrain from using the device and contact OMRON or a sales representative for service and repair.

zContinued use of the failed device may result in electric shock or fire.

Do not use damaged cables.

zContinued use of the damaged cables may result in electric shock or fire.
