Activate
Bluetooth
The
Bluetooth
feature in a VR4-UWM receiver must be activated before the VUE software will be able to
find and connect to the VR4-UWM. Activation requires a specially designed Communications Key (also
referred to as “Comm Key”).
The Communications Key is a stepped cylinder made of black plastic material. A strong magnet is contained
in the smaller end of the Comm Key and should be kept away from any magnetically sensitive materials. An
orange float is attached to the Com Key case for easier handling and locating of the key. This key functions
with other VEMCO receivers that use a Comm Key, such as the VR2W.
WARNING
The Communication Key contains a
strong magnet
. Do not put it near
magnet-sensitive materials, such as
CRT computer monitors or magnetic
stripes, as they could be seriously
damaged.

Watch for a flashing red
light on the VR4-UWM’s
top, flashing at a one
second interval, and then
remove the key.
STEP 2
Bright red flash
every second
The flash pattern in a VR4-UWM indicates the mode
(state) the receiver is in at the time. A bright, long
flash once a second indicates that the VR4-UWM is
now ready for wireless communication but is not yet
in communication with VUE.
Place the magnetic Communication Key
against the circular indent in the
VR4-UWM’s lid.
STEP 1
NOTE:
Due to
Bluetooth
characteristics in water,
the VR4-UWM must communicate with the
Bluetooth
USB adapter
through air
(typical
range is 10 meters).
