Radio Shack SYSTEM 440 - Manual (Page 17)

17
All System 440 modules are set up as the MAIN module. If you install
additional modules, you must program each additional module as an ex-
tension (
EXT ) module, or incoming calls might be disconnected. Follow
these steps to program an additional module as an extension ( EXT )
module:
1. Hold down both REVIEW keys for over 8
seconds until this display appears:
2. Release the REVIEW keys and press
DELETE to set the module as an extension.
The asterisk moves next to EXT .
MOUNTING THE MODULE
You can place the module directly on a desk, shelf, or table, or mount it
on a wall. To mount the module on the wall, you need two screws (not
supplied) with heads larger than the holes on the back of the supplied
mounting bracket.
