G-WAVE amplifiers are

shipped from the factory

with 30 dB of attenuation

dialed in. Units are not

shipped with full gain to

ensure input signal does

not overdrive the ALC

limitation of the unit.

If the attenuation rotary

switch is dialed to 30 –

This indicates the unit has

30 dB of attenuation and

is running on minimum

gain potential of the

system.

thatmaybepopulatedintotheO26pin‐out.Thesealarm

contactsarenotincludedasastandardandmustberequested

attimeoforder.

To add gain back to the

system, dial back the

rotary switch, slowly, (28,

26, 24, 22…) until the

Downlink ALC LED turns

on. This indicates the unit

has reached maximum

output power (per unit’s

specification).

At this point, dial one step

of attenuation back into

the unit to turn the

Downlink ALC LED off.

At this point the Downlink

path of the system has

been commissioned.

Repeat the above

procedure on the Uplink

path.

Warning!

Input Signal Level greater than -30

dBm may cause damage to the

system.
