2. Insert the upgrading SD card (prepared as instructed above) into the service slot at the back of the set. Insert the SD card with its logo-printed face
upward (visible). Be careful not to insert the SD card in the wrong way. Otherwise the card may come into the set and fail to come out.

CAUTION: Now the monitor microprocessor software starts getting upgraded. Be very careful not to turn off the power while the software is being
upgraded. Otherwise the software will fail to upgrade itself and the set will fail to get started.
