Try this, it may work for some earlier GE remotes: Use the set up procedure for older One-for-All remotes that use 3-digit setup codes (see [Link: hifi-remote.com]
, and be sure to try both the URC2060 and URC4060 methods) but add 17 to the setup code you want to use. E.g. If the code list gives 054 as the setup code for Magnavox, then use 054+17 = 071.
No guarantees, but it may work.
