1. At the > prompt, type SET; press Enter.
2. From the Main Setup Menu, type A; press Enter to display the

Amplifiers Menu.

3. Select 5, Low Noise Amp Attenuation Setting, and adjust attenuation if

necessary by typing a number in the range of 0 to 15; press Enter.  If no
change is required; press Enter.

NOTE: Attenuation steps are nominally 1 dB, but overall system gain
may vary.  Consult the enclosed test data sheet for approximate system
gain at each attenuator setting.

4. For each downlink power amplifier entry in the menu (1-4), assure that all

amplifiers are configured to the proper frequency band.  Amplifiers that
display NONE for a frequency band are disabled.  Normally a PA should
not be installed in the position corresponding to the PA number in the
booster when this entry is displayed.

The MR Booster operates in two modes: standalone and repeater-controlled.
Alarm settings are set with the repeater software when the booster is remotely
controlled via the I

2

C bus.  In standalone mode, alarms are configured with

the MR Booster software.  Fully configuring all the alarm thresholds and
parameters in a standalone system is a detailed process.  Only a summary of
steps to configure alarms is described in this section. For specific information
on setting up alarms, see Appendix A.
