How do I Install the Bilingual Software Card into a Vanguard 2/PLUS.
IMPORTANT! Your Vanguard must be Serial Number 2100VG or higher to run 5.06 + software and have Deviation 5 installed on the circuit board. If the Vanguard2 or Vanguard PLUS has been repaired since August, 2009 this deviation would have been added by a PRC Technician. If you are unsure if your device has this deviation, please Call (1-800-262-1990) or Email PRC service (service@prentrom.com) with the Serial Number of the device to confirm this. If the device does not include this deviation, the unit will need to return to PRC.
Note: If you have customizated vocabulary that you want to keep, you must first perform a Memory Transfer to Save the User Area. If you have Infrared Commands stored in the device you want to save, you must Save Entire Device Contents to save the Commands. If you do this however, your new Bilingual default overlays will be erased and replaced with your vocabulary.
BEFORE YOU BEGIN: If your battery charger is plugged into your device, unplug the battery charger.
Gently place your Vanguard face down on a flat surface.
Remove the wire stand from the case by pulling the sides of the stand from their holes.

Unscrew the two battery door screws as seen in the picture above.

Put your fingers in the finger slots and pull the door latches toward you.
Remove the door.
You see the battery pack plugged in.
Lift the battery pack out of the case. Just rest it on the edge of the case until you unplug it.

Unplug the battery pack by grasping the red and black wires as close to the plug as possible. Gently wiggle and pull on the wires until the plug comes out of its socket. Do not yank or use force on the wires.
Now turn your device so that the side panel with the picture of thin rectangles labeled A, B and C is facing towards you.
Open the door that covers the side panel. See the picture above and below.

When the door is opened, you can see the system software card in its slot. There is a tape tab on the end of the card.
Pull on the tape tab to remove the software card. Notice the slot the card was in.
If you want to keep the old card, put it in a safe place.
Find the new card that came with this update. Place it in the same slot the old card was in. The side with CE on it should be facing up and the piece of tape should be pointing toward you. Push the card into the slot until you feel some resistance. Push past the resistance until the card will go no further. If you pull very gently on the tape, the card should not come out. If it does, re-seat it. Then shut the side panel door.
Now turn the device so the empty battery area is facing you.

Plug the battery back in. Make sure the plug is securely attached in the socket.

Replace the battery back in the case. Fold the wires if necessary to make them fit between the end of the battery pack and the device case.

Put the battery door back on. Replace and tighten the screws. Replace the wire stand.
Your device will automatically restart and load the new software.
If you saved memory before you started: Once your device has rebooted, you can transfer your saved vocabulary into your device. Select an English User Area to load into.
Vanguard 2 Memory Reload
Memory: If you saved your memory, use the Transfer Memory Menu in the Toolbox to transfer the memory back into the device. Remember: Loading your customized vocabulary will erase some or all of the default Bilingual Software on this new card.
Important Note about PCS Symbols: If you were using the PCS Symbols on your Vanguard and updated your software, you will need to re-activate the PCS Symbols by re-entering the password. If you do not have your password, you will need to contact PRC Sales Department 1-800-262-1933 and tell them you need your original PCS symbol password. You must also supply them with the serial number of the device and the Keycode within the unit.
