BLE*/* Installation and Operation Manual

9 Check the ac voltage setting (jumper J1, Figure 2-6).

J1 position Description

The voltage must be greater than 38 Vac as read with a true rms voltmeter or 42 Vac

when using a conventional, average reading, ac voltmeter.

The voltage must be greater than 55 Vac when read with a true rms voltmeter or 61

Vac when using a conventional, average reading, ac voltmeter.

Check the dc voltage. Verify that it is between 23.6 V and 24.4 V and re-install the input

pad.

11 If necessary, rebalance the amplifier following the instructions in Section 3, “Amplifier

Setup.”

12 Check the tightness of the electronics chassis cover screws (10 to 12 in-lbs.) and electronics

chassis hold-down bolts (18 to 22 in-lbs.).

13 Check the condition of the RF and weather gaskets and replace them if necessary. If needed,

also apply a light coating of silicone grease.

14 Close the housing and use a torque wrench to sequentially and progressively tighten the

housing bolts to a final torque of 6 ft-lb in the sequence specified on the housing cover and

illustrated in Figure 5-2.
