Regarding the Use of Wireless Devices (TR71A, TR72A, TR-75wb)

Precautions when Installing Wireless Communication Devices

Wireless signals are affected by device placement and interference caused by other environmental factors. The following factors can especially cause an unstable wireless connection, please be mindful of them when deploying devices.

Physical Objects:
Placing wireless devices far from each other and/or near to obstacles (such as metal objects, concrete, plants, etc.) may lead to a poor wireless connection.

Electrical Interference:
Placed near cooking equipment such as microwave ovens or communication devices that generate electromagnetic waves.

Access Point Capacity:
Having many devices connected to one access point simultaneously.

Regarding how many wireless devices can simultaneously connect to an access point and still maintain stable connections, please contact the manufacturer of the wireless access point.

Channel Congestion:
Using multiple wireless LAN access points with the same communication frequency channel.

Change the wireless LAN access point settings to assign a non-overlapping channel to each access point.

Note: If unstable wireless connection continues, not only will more data transmission errors occur, but battery life will also be shortened.

Bluetooth low energy

Bluetooth low energy LAN (IEEE 802.11b/g/n)

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.

Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
