When a radio interference is present at a specific frequency,
communication is maintained by moving to another frequency.
Communication time
When the communication competes with other systems (Wi-Fi, etc.),
the unit changes to another frequency to continue communicating.
Technical Data
Frequency Hopping (FHSS: Frequency Hopping Spread Spectrum)
A communication technology that uses spread spectrum transmission with frequency hopping to rapidly switch the
frequency. Because the frequency rapidly changes all the time, this communication method is resistant to radio wave
interference due to refl ections or noise from other wireless equipment, while ensuring a high level of data security.
Multiple systems can be installed in the same area, and it is a suitable technology for point-to-multipoint communication.

Compliance and a test report may be required in some cases. Please contact SMC for further details.
This product communicates by radio waves, and the communication may stop instantaneously due to ambient environments and operating methods.
SMC will not be responsible for any secondary failure which may cause personal injury, or damage to other devices or equipment.
When several units are installed closely to each other, slight interference may occur due to the characteristics of the wireless product.
The electromagnetic waves emitted from this product may interfere with implantable medical devices such as cardiac pacemakers and cardioverter
defi brillators, resulting in the malfunction of the medical device or other adverse effects.
Please use extreme caution when operating equipment which may have an adverse effect on your implantable medical device. Be sure to thoroughly read the precautions stated
in the catalogue, operation manual, etc., of your implantable medical device, or contact the manufacturer directly for further details on what types of equipment need to be
avoided.
The communication performance is affected by the ambient environment, so please perform the communication testing before use.
