• An object, such as your body, physically blocks the radio
signal.
If the Bluetooth signal is lost, move the Bluetooth device closer to the
data collector or try to eliminate the source of interference. The
connection will then usually be reestablished automatically.
Note: The operating system resets the Bluetooth connection when the
Ranger is powered on. If the Ranger is powered off while using
Bluetooth, you should wait at least 10 seconds after powering it back
on before using any function where Bluetooth communication will
occur. This is to allow enough time for the Bluetooth connection to
reset.
Warning: It is not recommended that Bluetooth communication be
used while logging GPS data to use for post processing. This scenario
requires constant and reliable communications between the data
collector and the receiver, which can only occur when using a
communication cable.
Bluetooth can only be used on a Ranger when the following two
requirements are met:
• The peripheral hardware has Bluetooth built in and is
explicitly supported by Survey Pro.
• Your Ranger includes the Bluetooth hardware.
Bluetooth hardware is included on the Ranger 500X, optional on the
Ranger 300X and not supported on the original Ranger. The
following two steps explain how to determine if Bluetooth hardware is
installed on a Ranger 300X.
1. Exit Survey Pro if it is running to return to the Windows
