7.3.3 Manual Gain Control
Figure 7-10 Control Tab – Manual Gain Control

DL/UL Gain: Gain levels of the repeater can be specified here

DL/UL ALC Level: Prevents the output power from exceeding the specified value

DL/UL Output ALC Offset: If any ALC attenuation has been applied, the system will release this
attenuation when the signal level drops by the specified level

DL /UL Gain Balance ON: Allows the user to enable or disable the gain balance. When gain balance is
enabled, the delta value between the downlink and uplink gains remain constant

Figure 7-11 Control Tab – Alarm & Battery Alarm Settings

DL Signal Low Level: Allows the user to specify how low the signal can be before triggering a “Downlink
Signal Low” soft-fail alarm

DL Signal Not Detected Level: Allows the user to specify how low the signal can be before triggering a
“Downlink Signal Not Detected” soft-fail alarm

DL RF Power Level: Allows the user to set a maximum deviation value for the downlink RF power before
triggering a “DL RF Power Level” soft-fail alarm
-
For example, if the input signal is -50 dBm and the gain is set to 60 dB, the expected output power
should be 10 dBm. If the Downlink RF Power alarm value is set to 6dB, then a soft-fail alarm will
trigger if the output power falls below 4 dBm

DL Over Power Level: DL Over Power Alarm will trigger when the DL output level exceeds this level

UL Over Power Level: UL Over Power Alarm will trigger when the UL output level exceeds this level

Battery Check:

Check All – All battery related alarms are checked which include Battery Fail, Battery Not Installed,
Low Battery, and Battery Not Charge

Except Install – Only Battery Fail, Low Battery, and Battery Not Charge alarms are checked

Check Off – Does not perform any battery check

Battery Not Charge Check:

On – Checks for the Battery Not Charge alarm

Off – Disables the check for the Battery Not Charge alarm
