Connecting GPS Devices via Bluetooth
Detaching Bluetooth units from the USB port
Before detaching Bluetooth units from the USB port, always select [Disconnect] as shown in
step 5. Follow the instructions displayed to terminate the connection.
The connection with the Bluetooth unit will not be terminated if you simply turn off the camera. If
you detach a Bluetooth unit while the connection is still active, attach the Bluetooth unit again
and follow the preceding steps to terminate the connection.
Power Management

If you will not use a wireless or wired LAN at the
same time as the Bluetooth unit, set
[Communication mode] to [Disconnect]. The
camera battery drains faster under settings other
than [Disconnect] because power saving is
disabled.
