This file includes a basic layout with all available functions and descrete codes not available on the manufacture's remote (Ex. Upconvert Resolution button on front of DVD). Also includes all 256 IR codes, some of which some are not used, and access to the EEPROM Options area.
Has discretes/learned/macro commands for: 2x Back/Fwd; 4x Back/Fwd; 16x Back/Fwd; 100x Back/Fwd; Factory Reset; LG Pluge Screen; EEPROM Edit Screen. Upconvert mapped to Guide, Last mapped to Prev Ch, and Skip +/- mapped to CH+/-. Tested on the LG which I have, but the Zenith is the same model and should work fine.
The first device translates all the codes found on the original remote with some added functionality, such as a discrete UPCONVERT button and separate chapter skip and FF/REV buttons. The second device holds 2 miscellaneous codes not found on the original remote, so use with caution: a test pattern and factory reset. I searched all 256 codes for this remote and there is no power off discrete code.
