1.The amplifier is supplied from the factory with the passive reverse module installed. For active reverse, see installation on next page.

2.The amplifier has a forward bandwidth of 54-860 MHz with a maximum of 40 dB gain.

3.The optimal input level for proper amplifier operation and to meet specifications is 0 to 20 dBmV.

4.The optimal output level for proper amplifier operation and to meet specifications is 30 to 46 dBmV.

5.The optimal levels for return path is input 3-18 dBmV, and output 20-35 dBmV* (*when reverse amplifier option is used).

6.The input slope control is used to equalize the input signal.

7.The gain control is used to adjust the output level of the amplifier.

8.The second slope control is used to adjust the slope or tilt of the output of the amplifier.

9.The reverse slope and gain control perform the same functions on the return path when the reverse amplifier module is utilized.

1.Unplug amplifiers and remove input & output cables and terminators on test points.

2.Remove the 8 Phillips head screws holding front cover on.

3.Loosen the 10 Phillips head screws holding the end covers on and lift off front cover.

4.Remove all 3 / 8-32 nuts and washers on the F ports.

5.Remove the loosened Phillips head screws holding the left end cover on and remove cover.

6.Unplug the power cable connecting the forward amplifier module to the power supply P.C. board.

7.Gently lift out the two amplifier modules from the housing.

8.Separate the two modules and set the passive reverse module aside.

9.Carefully line up the connectors on the amplifier module with the connectors on the reverse amp module and press the two modules together.

10.Reinstall the modules back in the housing reversing the procedure used for removing. (Note: Be Sure to Plug in the Amplifier Module Power Cord).

11.Tighten down all screws and nuts with a screwdriver and wrench.

12.Install reverse amplifier label (supplied with reverse amp module) on front cover, lining up the holes in the label with the holes in the cover.
