DRAFT

Equipment Warm-up

Warm-up BTS equipment for a minimum of 60 minutes

prior to performing the BTS optimization procedure. This

assures BTS site stability and contributes to optimization

accuracy. (Time spent running initial power-up,

hardware/firmware audit, and BTS download counts as

warm-up time.)

NOTE

Before installing any test equipment directly to any BTS

TX OUT connector, verify there are NO CDMA BBX

channels keyed. At active sites, have the OMC-R/CBSC

place the antenna (sector) assigned to the PA under test

OOS. Failure to do so can result in serious personal injury

and/or equipment damage.
