Usage precautions
■ About radio waves used by the clicker
The clicker uses radio waves on the 2.4 GHz band. When using the clicker, a radio station
license is not necessary. However, please note the following precautions.
Do not use the clicker near the following:
■ Microwave ovens or industrial, scientific or medical equipments, such as pacemakers
■ In-factory radio stations for mobile unit identification systems (radio stations that require a
license) used in production lines of factories.
■ Specified low power radio stations (radio stations that do not require a license)
■ IEEE802.11b/g/n wireless LAN devices
When the clicker is used near any of the equipment mentioned above, it is possible that
electric wave interference could occur.
When using the clickers, keep at least 20cm distance between the clickers.
Do not cover the upper part of the clicker with
your hand. The wireless connection with the
wireless adapter may be degraded.
In an environment where there are many
obstacles, the wireless connection with the
wireless adapter may be degraded.
■ About wireless equipment used on the 2.4 GHz band
This frequency bandwidth is the same as for industrial, scientific, and medical equipment such
as microwave ovens, mobile unit identification systems (radio stations that require a license)
used in factory production lines, and specified low-power radio stations (radio stations that do
not require a license).
■ Before using this product, check that there are no radio stations for mobile unit identification
systems or specified low-power radio stations nearby.
■ If this product emits radio waves which interfere with in-factory radio stations for mobile unit
identification systems, cease the use immediately and stop generating the radio waves. For
information on countermeasures, etc. (for example, erecting partitions), contact one of our
sales offices whose details are provided at the end of this manual.
■ If this unit emits radio waves which interfere with specified low-power radio stations used for
mobile unit identification systems, or causes similar problems, contact one of our sales offices
whose details are provided at the end of this manual.
