Wireless Equipment
Precautions relating to the frequency used by this device
In addition to industrial, scientific, and medical equipment such as microwave ovens, static wireless
stations (permit required) used for mobile identification in places such as plant manufacturing lines and
specified low-power wireless stations (no permit required) operate on the same frequency band as this
device.
(1) Before using this device, ensure that no static wireless stations or specified low-power wireless
stations for mobile identification are being used in the vicinity.
(2) In the event of instances of electromagnetic interference from this device to a static wireless
station being used for mobile identification, either promptly alter the usage frequency, or halt the
electromagnetic discharge
(3) If other problems arise due to reasons such as electromagnetic interference from this device to a
specified low-power wireless station being used for mobile identification, please contact DENSO
WAVE through QBdirect.
Requests to system designers
(1) Communication may not be possible depending on the environment in which the device is being
used. Ensure that problem-free communication is possible prior to use.
(2) Use a program capable of retransmitting data if communication fails.
(3) If the BHT is introduced into an environment in which a device using 2.4
GHz
waveband
electromagnetic waves is operating, or if another device using 2.4
GHz
waveband
electromagnetic waves is introduced following introduction of the system, run all devices and
ensure that communication with the BHT is possible prior to use.
(4) Check communication once again prior to use if any changes are made to the usage environment
(addition of household appliances, movement or addition of shelves, equipment and so on)
following introduction of the system.
