2. Remove the instrument from its soft case and place it upside
down on a padded surface to protect the large knob on the front
of the instrument.
3. Remove the RF input adapter (if installed), using a 7/16 in
wrench. Remove the nut and the two washers from the RF
connector, using a 9/16 in wrench, and push the RF connector
through to the inside of the instrument. To protect the instrument
from water damage, be careful not to misplace the rubber gasket
on the end of the RF connector.
4. Working from the back of the instrument, remove the ten screws
that hold the instrument together.
5. Tip the rear part of the instrument back to partially open the
instrument case, without stressing the ribbon cables or the RF
input cable. Remove the instrument carrying strap and set it
aside. Separate the instrument into two parts and lay them next to
each other on the work surface, as shown in Figure 6–1.
Note the water-resistant gasket in the instrument front casing.
Inspect the gasket for damage, and replace if necessary. Make
sure that the gasket is firmly seated in the groove all the way
around the front casing, and locked in place by small plastic tabs
along the groove.
6. Disconnect the ribbon cable from the Back Board circuit board
assembly.
7. Proceed to the instructions for replacing the desired module.
