Changing the Test Module
Use the following procedure to remove the current test
module from the Network Master mainframe and install a
new test module.
To change the test module:
1. Power down the unit, if current operating.
2. Disconnect the AC charger/adapter, if currently
connected.
3. Loosen the captive fastener on the back panel of the
current test module (see item 2 in Figure 2-2 on
page 2-6). When fully loosened, the fastener slides
out of, but remain attached to, the test module.
4. Open the battery compartment (see Figure 2-2 on
page 2-6 for location) and remove the battery pack
or AA Ni-MH batteries (if installed).
5. Hold down the module release latch (white plastic
latch in the battery compartment – see item 2 in
Figure 2-3 on page 2-8) while pulling forward on
the Network Master mainframe to separate it from
the test module.
Let go of the module release latch after the Network
Master mainframe separates from the test module.
CAUTION
!
The Network Master mainframe and test module fit
together snugly. Use caution when removing the
mainframe from the module.
6. To install the new test module, align the 2 tabs on
the back side of the Network Master mainframe
(the end opposite of the 100 pin connector) with
