6.Turn the instrument around so that the front of the instrument faces to the operator's left. Desolder the 6, 5, 4, and 0 (blue, green, yellow, and black) wires from the A1 assembly.

7.To remove T1 power transformer and its mounting bracket, unscrew the four screws located on MP20 (mounting bracket). Separate transformer and the mounting bracket by removing the four long screws passing through the transformer case.

8.To remove the A1 assembly disconnect W12 (gray ribbon cable) at AlJl board connector, unscrew the two screws at the VR3 heat sink, and turn the three board mounting stand-offs a 1/4 turn counterclockwise.

9.To remove MP 13 (main deck) and MP 14 (RF module), remove the six Torxhead screws located on the top and bottom of MPl (front frame). Remove the six screws connecting MP2 (side struts) to MP13 (main deck). While supporting MP9, MPlO (front- and sub-panel) in one hand, carefully slide MP13 (main deck) forward through the front frame opening just enough to reach the inside cable connections.

Be careful that you do not bend the coax cables. Possible attenuation or interference of the RF signal may result.

a.When inside connections can be reached, use a 5/16 open-end wrench to disconnect the semi-rigid coaxial cables from the front-panel connectors.

b.Carefully set aside the front panel and slide the main deck assembly out of the instrument chassis.

To remove the main deck on Options 020 and 021, disconnect the input cable connectors at the back panel. Remove the main deck screws, then lift one side of the Main deck up until it clears the side strut.

10.To remove MP14 (RF module) from MP13 (main deck), remove the four screws that hold the module to the main deck.

38.Instrument Assembly Procedure

Note that Option 020 and 021 instruments differ from the standard and other option models in that the main deck and transformer locations inside the instrument are reversed, when compared to the standard and other option models as shown in Figures 7 and 8. In Option 020 and 021 models, the RF module is in the rear of the instrument), and the transformer is mounted in the front left corner.

Use the correct torque wrench when installing sub -miniature connectors.

Do not exceed the following torque settings for this instrument:

1.5N'm for the 3 mm (T IO) screws,

2.0N.m for the 4 mm ( T I S ) screws.
