The GefenToolBox HD Pattern Signal Generator should be mounted vertically in
a wall or cabinet with wood/drywall screws as shown in the diagram above. There
hould be an inch or two of clearance between the edges of the unit and an
walls or vertical surfaces to allow for enough clearance for insertion and removal
For installation on a drywall surface, use a #6 drywall screw. It is recommended
when installing on a drywall surface that studs be used to secure the Splitter
