MB*/* Installation and Operation Manual
Section 4
Bench Testing
Motorola’s recommended procedure for placing a new MB*/* into service is to fully test it on the
bench before it is field installed. There are specific alignment procedures that ensure proper
functioning of all components and simplify final installation. If the MB*/* is properly aligned on
the bench, only minor adjustments may be required in the field.
The following subsections provide instructions to bench align the MB*/*.
Before You Begin
The MB*/* is shipped with a 20 ampere blade-type fuse in the three active ports of the dual
output amplifier module for overcurrent protection.
CAUTION!
To avoid applying 60/90 Vac to the test equipment during testing, remove the fuse from the connected
output port (
F2 or F4) illustrated in Figure 2-11. Terminate all unused ports.
Open the housing and remove the chassis cover. Refer to your system drawings or records to
confirm the presence of the required options as described in Section 2, “Overview,” Options and
Accessories.
