Notes
1. The OPL 9712 complies with Bluetooth standards. The device that communicates
with the OPL 9712 must support the same SPP. 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 OPL 9712 may vary due to obstacles
and radio wave conditions between the OPL 9712 and the device to which the
OPL 9712 is connected. Conditions on the host device may also affect the
communication speed and communication range of the OPL 9712.
3. The prospective distance may vary based on environmental characteristics. Also
note the following frequency description.
