PROPRIETARY NOTICE
This document and the technical data herein disclosed, are proprietary to Racal Instruments, and shall not,
without express written permission of Racal Instruments, be used, in whole or in part to solicit quotations from a
competitive source or used for manufacture by anyone other than Racal Instruments. The information herein has
been developed at private expense, and may only be used for operation and maintenance reference purposes or
for purposes of engineering evaluation and incorporation into technical specifications and other documents which
specify procurement of products from Racal Instruments.

FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer, ensure
the common connector is connected to the neutral (earth pole) of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground (earth)
conductor of the power outlet. Do not use a two-conductor extension cord or a three-prong/two-
prong adapter. This will defeat the protective feature of the third conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power
applied and protective covers removed. Read the procedures and heed warnings to avoid “live”
circuit points.
Before operating this instrument:
1. Ensure the instrument is configured to operate on the voltage at the power source. See
Installation Section.
2. Ensure the proper fuse is in place for the power source to operate.
3. Ensure all other devices connected to or in proximity to this instrument are properly grounded
or connected to the protective third-wire earth ground.
If the instrument:
-fails to operate satisfactorily
-shows visible damage
-has been stored under unfavorable conditions
-has sustained stress
Do not operate until performance is checked by qualified personnel.
Optical Ports WARNING: To avoid eye damage, do not look directly into the optical output
ports while there is an optical signal connected to the input port. Always attach
the output ports to a receiver or cover with the supplied dust caps before
enabling the source signal to the input port.
