Getting Started
Required Tools
A number 2 (#2) Phillips Screwdriver
A small flat blade screwdriver
#8 TORX wrench
Materials needed for Service Procedure
One (1) SmartSDR MicroSD Card
One (1) piece of Kapton tape
Two (2) adhesive Warranty Void stickers
Preparing to Install the MicroSD Card
Removing the Chassis Feet
Remove the four (4) feet from the chassis using a #2 Phillips screwdriver as shown in the image below.
Retain the chassis feet and screws for re-installation later.

The image below shows all four (4) chassis feet removed.
Removing the Bottom Cover
The bottom chassis cover for the FLEX-6000 must be removed before the MicroSD card can be installed.
A #8 TORX wrench remove the three (3) short Bottom Cover Side screws from the left side of the FLEX-
6000.
Then remove the remaining three (3) short Bottom Cover Side screws from the right side of the FLEX-
6000. Retain the Bottom Cover Side screws for re-installation. The image below shows the removal of the
left side bottom Cover Side screws.

After removing the bottom cover side screws remove the six (6) stainless steel (silver) Bottom Cover
screws using a #8 TORX wrench. Retain the bottom Cover screws for re-installation. The image below
shows the removal of the Bottom Cover screws.
Once the bottom cover retaining screws have been removed, gently pull the Bottom Cover upwards to
remove it from the FLEX-6000. The image below shows the removal of the Bottom Cover.

Removing 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 the RF Isolation Cover
The RF Isolation cover is located on the bottom of the radio. It is a rectangular silver cover with
perforated holes in it. There are red or gold warranty security seals installed to prevent the customer
from opening the enclosure. See the picture below.

Removing the RF Isolation Cover
Using a knife or flat blade screwdriver, remove the security seals so the RF isolation cover can be
removed. See the image below of the RF Isolation cover with the warranty security seals removed. Note
some of the seal adhesives will remain on the RF Isolation cover.
Take note of how the RF Isolation cover is seated in the shield housing’s “teeth“ (retaining tabs) for
reassembly purposes.
Using a flat blade screwdriver, gently pry up the RF Isolation cover. It is best to do this at several locations
so that the cover does not twist and separate the retaining tabs. This is shown below in the next two
images.

Lift up and remove the cover.

Remove the MicroSD Card
The next step is to remove the MicroSD card from the FLEX-6000.
The MicroSD card is located adjacent to the FPGA processor/fan assembly. There may be a piece of
Kapton tape covering the top of the card retaining clip. If so, carefully remove the Kapton tape.
Gently slide the silver MicroSD card retaining clip away from the FPGA processor/fan assembly so that it
releases and lifts up as shown below.
Using a non-metallic object to lift up on the end of the card nearest to the FPGA processor/fan assembly,
the MicroSD card should easily lift out of the card socket so it can be removed.

Installing the new MicroSD Card
Once the existing MicroSD card has been removed, install the new MicroSD card that has been formatted
and has the SmartSDR firmware installed. Installing an unformatted MicroSD card without the SmartSDR
firmware installed will result in the radio not booting.
Installing the New MicroSD Card in the Card Socket
Make sure the silver retaining clip is in the unlocked and upright position. Carefully place the new
MicroSD card in the card socket. There is a plastic “key” on the right-hand side of the MicroSD card that
aligns up with a key slot on the card socket. Make certain that the card is properly seated in the card
socket as shown below.

Carefully fold down the silver retaining clip so that it is flat against the MicroSD card. Slide the silver
retaining clip towards the FPGA processor/fan assembly making sure that the MicroSD card does not slip
or move in the socket. This will lock the MicroSD card in the card socket as shown below. This will result
in the card not making proper contact with the card socket’s electrical contacts causing the radio to fail to
boot up.
Installing the XXX Tape over the MicroSD Card Socket
To prevent the retaining clip from coming unlatched when the radio is shipped, place a strip of Kapton
tape over the top of the MicroSD card socket as shown below.

Reinstall RF Isolation cover
Note: Before reinstalling the RF Isolation cover, you may want to boot the radio to ensure that the new
MicroSD card is installed properly. Be very careful when booting the radio with the chassis and RF
Isolation covers removed.
Reinstall the RF Isolation cover. Make sure that the RF Isolation cover is inserted properly in the RF shield
housing’s retaining tabs. It is best to insert the cover on the side of the housing underneath the side of
the chassis first and then gently press down on the side facing away from the chassis. Once installed it
should like the image below.
Once the RF Shield cover is installed, put two (2) new Warranty seal stickers on the RF Isolation shield in
the same place where the previous stickers were located. Be careful not to place any of the stickers on
the PCB board. The warranty seal sticker should only be on the silver RF Isolation housing and cover as
shown below.

Reinstalling the Bottom Cover
Replace the bottom chassis cover on the FLEX-6000. Orient the cover so that the row of vent holes on the
bottom cover are on top of the side fans towards the front of the FLEX-6000 as shown below.
After reinstalling the bottom cover install the six (6) stainless steel (silver) Bottom Cover screws using the
long portion of the #8 TORX wrench. The image below shows the installation of the Bottom Cover screws.

Using the long portion of the #8 TORX wrench install the three (3) short Bottom Cover Side screws on the
left side of the FLEX-6000. Then install the remaining three (3) short Bottom Cover Side screws on the
right side of the FLEX-6000. The image below shows the installation of the left side bottom Cover Side
screws.

Reinstalling the Chassis Feet
Reinstall the four (4) feet on the chassis using a #2 Phillips screwdriver as shown in the image below.
The finished re-installation of the bottom cover and chassis feet should look like the image shown below.
