6) RF OUTPUT AND AURAL CARRIER LEVEL ADJUSTMENT
A) Using a field strength meter or spectrum analyzer, set the video carrier to the desired level with the RF
output level control (typically +55dBmV).
B) Tune to the aural carrier, which is located 4.5mHz above the video carrier.
C) Adjust the aural carrier level control (A/V) to the desired level, typically 15dB below the video carrier.
CAUTION: Reducing the visual/aural carrier ratio to less than 15dB can result in high spurious signals
in adjacent channels.
D) Output Connection - The output signal is now present at the RF output port.
7) MISCELLANEOUS
A) The LCP-500-550 is BTSC compatible. The unit will automatically function with either stereo or
monaural audio carriers and will pass an SAP signal if present.
B) The LCP-500-550 is equipped with a 0.5A slo-blo fuse. For safety, and to maintain proper perfor-
mance of the unit, please replace only with an equivalent fuse.
C) When installing the LCP-500-550 in an equipment rack, it is best to leave an empty rack space
above and below the unit to allow for optimum air circulation.
