H20 dialing prefix

[arxaw]

Does anyone know how to access the installer menu to add a dial prefix in the H20-100 (mfg'd by RCA)?
The "front-of-the-receiver" key combination: MENU + > keys doesn't work on this model.

D* support was no help.

Never mind. I figured it out by trial and error.

Turn on the H20.
On the receiver (not the remote), Hold down the MENU & DOWN arrow keys for about 5 seconds. This will get you into the service menu where the dial prefix is added, among other things.
