2. While holding down the bezel, place the Volume Washer (16) onto the Volume Shaft. See
Figure 8-42.
3. Tighten the Volume Spanner Nut (17) by hand first to avoid cross threading. Then, torque the
nut with the Volume Spanner Bit at 8 in-lbs.
4. Place the Antenna washer (18) onto the antenna threaded hub as shown in Figure 8-42.
5. Tighten the Antenna Spanner Nut (19) by hand first to avoid cross threading. Then, torque the
nut with the Antenna Spanner Bit at 16 in-lbs.
6. Slide and ensure the Torque Adder (15) is fully seated onto the Volume Potentiometer's Hub.
7. Align the D-shaped part of the Volume Shaft with the D-shape hole in the Volume Knob (12)
and press the Volume Knob into place.
8. Align the D-shaped part of the Frequency Shaft with the D-shape hole in the
Frequency Knob (13) and press the Frequency Knob into place.
8.9.1.3 Assemble VOCON Board Assembly (G, N)
1. Inspect the Main Chassis (3) sealing surfaces to make sure there is no surface irregularities
such as scratches or indentations. Clean any debris or other foreign material.
2. Inspect the two thermal pads (8) on the front and back of the unit along with the
Coin Cell Pad (7) to confirm pads are clean and free of debris as shown in Figure 8-43.
Figure 8-43. Inspect Pads
3. Orient the Main Chassis (3) with the Frequency Knob (13) on top. Insert the
VOCON Board Assembly (36) into the chassis starting at a 45° angle and rotate the board
into place. Ensure the control top flex is located below the PCB, and is not being pinched
between the PCB and the casting. See Figure 8-44.
