Correction: The Apex box works with a el-cheapo RCA 3-in-1 Universal remote, alas, features such as 'display' and 'Guide' and others such as box volume/mute and signal meters are not available, but it will turn it on/off and change channels.
The same remote ($5 at K-mart) also works the DTVPal+ as well, and it will bring up the menu, and the number keys correspond to the numbered menus (such as '1' for Program Guide) and the LED of the remote blinks when in menu mode, so if you exit the menu for any reason the LED continues to blink until a device key is pressed and allows VOLUME to do the browse banner and CHANNEL Up/Down does channels. out of the menu mode (normal operation) channel up/down does nothing and volume only controls TV volume. 'ENTER' does the display. direct-entry for known channels is available, it would be 04402 for digital channel '44.2'
The codes to program are in the list of 'Satellite/Cable' receivers and it's for 'EchoStar/Dish Network'
Anyone with a Apex or other branded box will have only the Code Search to find it, as most brands such as that one aren't listed in Satellite/Cable box codes.
