Harmony provides the following special instructions when you add your device as model "DishDVR-921" (also available under its Device > More Options > FAQs):
-------------------------------------------------------------------------------
The Dish Network PVR is by default set to accept UHF/RF (radio frequency) signals only. The remote is capable of sending only IR (infrared) signals.

The remote will still be able to control your PVR, but you will first need to set the PVR's Language to accept the language the remote is using.

You must test the remote with each remote address on you device, until you find an address that controls your device.

Note: You should have updated your remote for the first time before trying these steps.

1. On the remote:
1. Press the Device button and select the Dish Network Cable box from the LCD screen. If you do not see the device on the first page press the Next button.
2. Now press Channel Up on the remote. If channel up works, you are done. If not, go to the next step.Note: The Dish 811 and 921 need to have the antenna disconnected before they will accept IR signals.
2. Press SYS INFO on your receiver's front panel. Note the Remote Address.
3. Press and hold SAT on the PVR remote until the mode button on the remote lights up (approximately 3 seconds).
4. Use the number pad on the PVR remote to enter a number (1-16).
5. Press #. If the address was entered correctly, the SAT mode will flash 3 times.
6. Press RECORD. Note: On the System Information screen, make sure the Remote Address that appears is the same as the one entered in Step 4.
7. Press SELECT/OK to close the System Information screen.
8. Go back to Step 1 to test if you have the correct remote address. If not, repeat these steps using the next remote address.
