Telex VEGA C-5110B, Instruction Manual

Page: 7 / 46

Installation
The C-5110B, C-5111, and C-5112 ten-line
tone-remote consoles may be installed in any
location convenient to the operator. Exposure
to extreme dampness, temperature, and
radio-frequency energy should be avoided, to
insure maximum reliability and operating life. The console is not designed to operate on lines
carrying direct current. If direct-current lines
are to be used, isolate the console with external
capacitors or with 600:600-ohm transformers
designed for the current involved.
The console has been factory-programmed for
single-console-per-line, two-wire half-duplex
operation and for +10-dBm/guard-tone output
into 600-ohm lines.
