I am trying to identify an old ZENITH remote. It is in the same vintage as the 3300/3400 types. It is newer than either. All I can do is describe it in hopes someone can identify it by model number(s). Then I can try to find the manual. A link to the manual would be nice. Here goes. Starting at the top, left to right the buttons are as follows. RECESSED PROGRAM BUTTON, POWER BUTTON(BLUE),flush device lights, TV/VCR/CATV, MODE BUTTON, MEMORY/ CH MAP/ VCR PLUS, RECORD(BLUE)/SEARCH/"C",SOURCE button/PAUSE.center main buttons cluster for VCR, MUTE/VOL/CHANNEL/FLASHBACK,below # buttons/ ENTER,MENU/ADJUST/SELECT/ADJUST/CC/QUIT. That is all of them in order. The 3300/3400 is programed by PRG push,TV button, enter code, then ENTER. The light blinks 3 times if valid. If correct or not. THIS remote does NOT program in that way even though the process and responses are the same. Any info welcome. The battery door is missing. That is where the model # is I presume. [email protected].
