I've had this issue with several remotes in the past. I received the following procedure from a Tier 2 tech. It has worked for me in most every case. I hope it works for you.



1. Reset RF Extender - Hold connect, plug extender into the USB Cable, once
plugged in keep holding down connect until the "RF" light begins to flash.
The RF light & the Status light should now be blinking at the same time.
Unplug the extender from the power outlet

2. Remove the Extender & the Remote from the account

3. Remote Safe Mode Firmware - Take the battery out of the remote, hold down
the "Off" button and plug USB cable in. When "Safe Mode Requested"
appears on the screen, let go of "Off"

4. Click on Downloads, select "Firmware" and click "Next", run through the
firmware upgrade for the remote

5. Once firmware is complete, click on "Next" and run through the connectivity
check

6. After connectivity is confirmed, the software will prompt you to update,
select "No"

7. Unplug the remote from the USB and put the battery back in the remote.

8. Extender in Safe Mode Firmware - Hold down the "connect" button and plug
the extender into the USB cable. Keep holding down connect until the "RF"
light begins to blink, the RF & status light should be blinking between each
other.

9. Upgrade the firmware on the extender. At 100%, the software will prompt you
to unplug the extender from the USB cable, plug it back in and then click on
"Next".

10. Once the connectivity check is complete, the software will once again
prompt you to update the remote, select "No".

11. You will now see that the remote & extender are re-added to the account,
click on "Control Devices" to select whether the devices are controlled with
the extender or the remote.

12. Once complete, change the "Theme" of the 890 remote. If the theme is set
to "Default", change it to "No icons" for example. Save the changes and then
go back into the "Themes" and change it to "Harmony Uppercase". Save.

13. Click on "Update Remote", you are looking for the software to prompt you
to plug the "remote" into the USB cable first, and then update the extender &
the remote.

14. After the update is complete, you want the remote to prompt you through
the remote & extender pairing

15. Once paired, the remote & extender should communicate properly once again.
