2) Disconnect the 6 VDC power connector on the

lower left side of the module.

3) Disconnect the control cable (one for each

channel module). The control cable is located at
the lower left side of the control module and has
a white plastic pull tab on it. 

4) Disconnect (3) Form-C control lines from the

top of the module. The lines are connected to a
terminal strip on the control module. The termi-
nal screws can be accessed through a slot on
the front of the control module. Use a small flat
blade screw driver (jewelers screwdriver).

6) The control module is held in place with either

mounting bolts or Phillips screws. Use a 5/16”
nut driver to remove mounting bolts or a #2 Phil-
lips screwdriver to remove mounting screws. Lift
the module up and out of the cabinet.

7) Reverse steps 6 through 2 to install the new

control module assembly.

The SBIII Control Module is field replaceable. Fol-
low the steps listed below in sequential order. The
required tools are a 5/32” hex head driver.

1) Turn off power to the signal booster.

2) Disconnect the AC plug on the right side of the

supply.

3) Disconnect the three (6 Volt) DC Output plugs

on the left side of the supply. 

4) Disconnect the three (28 Volt) DC Output plugs

on the left side of the supply. 

5) Remove the 12 hold down screws (5/32” hex

head) that hold the power supply assembly to
the cabinet. The screw heads are accessible
from the heatsink side of the assembly. Refer to
Figure 26.

6) Remove the assembly by puling it away from

the cabinet.

7) To install the replacement power supply reverse

steps 6 through 2. The power supply assembly
comes with an O-ring gasket which must press
up against the outside of the cabinet firmly and
squarely in order to provide a correct moisture
seal.
