926 B The Setup Menu: Camera Setup
The camera connects only to devices with which it has
previously been paired. Press the pairing button on the
WR-R10 wireless remote controller connected to the
camera to pair it with other devices.

As the camera will not communicate with devices with
which it has not been paired, this option can be used to
prevent signal interference from other devices in the
vicinity.
•
Given that each device must be paired separately,
however, PIN is recommended when connecting to a
large number of devices.
