Notes
1. This product complies with the Bluetooth 2.1 standard. The device that
communicates with this product must support either SPP or HID as well. For
other Bluetooth devices with other profiles we cannot guarantee a connection
before the products have been tested.
2. The communication speed and range of the product may vary due to obstacles
and radio wave conditions between this product and the device to which it is
connected. Conditions on the host device may also affect the communication
speed and communication range of the scanner.
3. The prospective distance may vary based on environmental characteristics.
Also note the following frequency description.
4. The frequency band of the electromagnetic radiation (2.4 GHz) used by this
product is shared by various other devices. Therefore, baudrate and
communication distance may be negatively impacted by other devices.
Baudrate and communication distance are affected by obstacles, wave
conditions, or a device at the other end.
5. This product is equipped with an antenna. Bringing this product too close to a
metallic object may degrade performance.
