HDMU 790 C

inal

proCedures

After installing the head-end station, upgrading accessories or installing mod-

ules it is necessary to tighten all cable connections, cable terminals and cover
screws in order to maintain compliance with current EMC regulations.

• Securely tighten the cable connections using an appropriate open-ended

spanner.

• After programming, connect the modulator output

to one of the input

sockets

of the output collector (page 10, fig. 4).

• Test the output level of the output collector according to the STC 160 assem-

bly instructions and set the output level required for the cable system.

• Mount the base plate and the front cover (see STC 160 assembly instruc-

tions).
