Select [Wireless remote (WR) options] > [Link mode] in the
camera setup menu and choose from the following options:
Option
The camera connects only to devices with which it has previously been paired.
As camera will not communicate with devices with which it has not been
paired, this option can be used to prevent signal interference from other
[Pairing]
devices in the vicinity.
Given that each device must be paired separately, however, PIN is
recommended when connecting to a large number of devices.
Communication is shared among all devices with the same four-digit PIN.
This option is a good choice for photography featuring a large number of
remote devices.
[PIN] If there are multiple cameras present that share the same PIN, the flash units
will be under the sole control of the camera that connects first, preventing
all other cameras from connecting (the LEDs on the WR‑R11a/WR‑R10 units
connected to the affected cameras will blink).
