Installing the Bluetooth Phone in the ECO.
Parts you received:
· Your ECO-14
· A cell phone
NOTE: You must be running 1.07 software in your ECO for the Bluetooth Card to be recognized. This software must be updated using the ECO Recovery CD and not via the website Software Update using a flashdrive.
Install the Bluetooth Card
With your device turned OFF, place the ECO face down so that the side with the card slots and switch connectors is facing you.
Insert the phone card into the larger card slot. The end of the card with the pinholes in it goes in first. The side of the card that has PRC on the label should be face up. Push the card into the slot until it clicks into place.
To remove the phone card, press one end of an unbent paper clip into the hole at the side of the card slot (see graphic above). Press down until the card pops out.
Install the Audio Cable
Place the ECO face down on a flat surface. The side that contains the switch connectors and the card slots should be facing you. Using a Phillips screwdriver, unscrew the screw on the top right corner as in the graphic above. Remove the screw and put it somewhere safe in case you need to use it some other time.
Remove the protective cover from the sticky tape on the underside of the cable mounting plate.
Place the screw that is already attached to the mounting plate in the empty hole. You do not have to do anything with the mounting plate screw—just put it in the empty hole.
Press the sticky tape to the ECO case to hold the mounting plate to the case.
Tighten the mounting plate screw just until the plate is secure. Do not over-tighten.
Plug the shorter cable into the connector it fits into on the phone card. Plug the longer cable into the small connector on your ECO that has the phone handset icon 
next to it.
