There is no model number on the sheet, just the name "H.E.A.R. Decoder". This unit is normally paired up with a tone remote unit like a Model 280 or Model 284.

The cable that plugs into the 38A is part number 709-7112 (and the price in fall 2006 was US$35). This is the generic cable with flying leads (as opposed to one that has a connector that is designed to plug into some other manufacturers equipment).
BTW the differences between a 38 and a 38A are changes to both firmware and circuitry. They are similar in function and name but internally they are essentially different products. It's not really practical to attempt a field upgrade.

Courtesy of the scanner of Barry Palmore we have the the complete, front cover to last page Zetron Model 48-Jr Repeater Patch Installation Manual (#025-9362C). Richard Schiller W4RSE took the eleven individual PDFs and made one big PDF file.
Note that this manual is available in two forms:
Here is a single zip file (507 KB) containing 11 separate PDF files, or here is a single large PDF file of the whole manual (562 KB). If you only need one section, like the schematic (which is in section 6) the zip file may be more appropriate.

Two different people sent in the files, one was Eric VE2VXT. If you have the bandwidth / download time / disk storage space I'd get the bigger one.

Anybody have the Instruction Manual, Repair Manual or Schematic?
Zetron, Simplexor, Worldpatch, Microconnect, Repeaterman, Europatch, Deadbolt and probably a few other terms are either service marks, trademarks, or some other legal mark and no infringement is intended. If Zetron had these files on their public web site we wouldn't need to.
