Remove the 1 x 2 transparent brick
from the top of the PFx Brick.
Carefully remove the IR sensor from IR
sensor connector by pulling upwards.

right-

of the IR connector as shown.
Power OFF the PFx Brick and remove any
external peripherals.

5
Insert USB cable into the PFx Brick
6
Launch the PFx App. You should see this
notification message indicating the PFx
Brick is in Service/Recovery mode.
If the PFx Brick no longer responds to USB connection to a host PC
with the PFx App, or from connections via Bluetooth, or becomes
unresponsive and/or behaves abnormally, it can be placed into
Service/Recovery
mode.
Service/Recovery mode will allow the PFx Brick
firmware to be updated with the PFx App and
hopefully restore normal operation.
Follow this procedure carefully to put the PFx Brick into
Service/Recovery mode.
This procedure should only
be used in extreme circumstances where normal
communication with the PFx Brick cannot be used.
Use caution when inserting/removing the IR
sensor. The IR sensor pins are delicate and
can be bent or damaged if mishandled.
Ensure the connector is plugged into the
right-most 2 pins of the 3-pin IR connector.
