LEDsandFaultAlarms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. *OscillationDetect(ODSC)andMOBILEareoptionalfeatures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. 14 | P a ge
