7) MISCELLANEOUS
A) This unit is equipped with video and audio I.F. loops. Both loops are connected with two type F short
jumpers. If these become disconnected or misplaced, then the OTM-3000-I will not perform prop-
erly.
B) If a scrambling unit is utilized with the OTM-3000 I, follow the instructions associated with the scram-
bler. The video I.F. output level is +40dBmV, and the audio carrier level is determined by the aural
carrier level adjustment - typically +17dBmV @ 15dB A/V ratio.
C) This unit is equipped with a 0.25 slo-blo fuse. For continued safety and to maintain proper perfor-
mance of the unit, please replace only with an equivalent fuse.
