'77 Zenith ChromacolorII SC600 remote

[zeno]

May sound crazy but what color is the on/off button ?
Should be blue. If its white, silver or orange you
prob have the wrong one.
Also IIRC the "ZOOM" feature started in J-line. All zoom sets
used the battery ultra remotes. ALL battery ones have standardized freqs.
Older clickers WERE NOT !.
Post the model number & I will look into it in the next few days
if you wish.
