No soldering is required to install this handy rebuild kit.
The Ni-Cad battery pack, charging jack, switch, and lamp socket are
pre-wired and ready to install. You'll need a 5/64inch (2mm) allen
wrench to open the case, small philips screwdriver to remove the switch
and bulb, and needle nose pliers to remove the charging jack. Note that
the charging jack has a small pin in the center for use ONLY with the
Color Viewer II. If your charging jack looks like a miniature earphone
jack you have a Color Viewer Model I and need the corresponding battery
pack.
