pad.
If necessary, rebalance the amplifier following the instructions in Section 3, "Amplifier

Setup."
Check the tightness of the electronics chassis cover screws (10 to 12 in-lbs.) and hold-down
12
bolts (18 to 22 in-lbs.).
Check the condition of the RF and weather gaskets and replace them if necessary. If needed,
13
also apply a light coating of silicone grease.
Ensure that the electronics chassis handles are folded down and that any cables between
14
the base and lid are not pinched.
Close the housing and use a torque wrench to sequentially and progressively tighten the
15
housing bolts to a final torque of 15 ft-lbs in the sequence specified on the housing cover and
illustrated in Figure 5-2.
