Replacing the Existing MicroSD Card
Once the bottom cover has been removed, the RF Isolation cover must be removed to access the
MicroSD card slot.
Locating and Removing the RF Isolation Cover
The RF Isolation cover is located at the top of the radio. You will see a large silver "RF can" (with
vent holes) that has a removable top. There may be a metalized plastic security label that
indicates your warranty will be voided if the tag is broken. This procedure will not void your
warranty since FlexRadio is instructing you to do it. Using a sharp-pointed knife or razor
blade, cut through the label so that the removable top can be easily lifted and removed.
If an ATU board is installed, you will have to remove three (3) screws and move it slightly out of
the way to remove the RF shield cover.
Using a Philips #1 screwdriver: remove screws 17and 18. Lift the RF can top off by gently prying
up on it between the metal "fingers" that hold the top of the RF shield in place around the edges
with a small flat blade screwdriver. It is best to do this at several locations so that the cover does
not twist and separate the retaining tabs.
