SAFETY AND PREPARATION FOR USE
WARNING: Dangerous voltages, capable of causing death, are present in this instrument. Use
extreme caution whenever the instrument covers are removed.
WARNING: Watch for overhead power lines when installing the FS700's antenna. Contact with power
lines can be fatal.
This instrument may be damaged if
operated with the LINE VOLTAGE
SELECTOR set for the wrong AC line
voltage or if the wrong fuse is installed.
Line Voltage Selection
The FS700 operates from a 100 V, 120 V,
220 V, or 240 V nominal AC power source
having a line frequency of 50 or 60 Hz.
Before connecting the power cord to a power
source, verify that the LINE VOLTAGE
SELECTOR card, located in the rear panel
fuse holder, is set so that the correct AC
input voltage value is visible.
Conversion to other AC input voltages
requires a change in the fuse holder voltage
card position and fuse value. Disconnect the
power cord, open the fuse holder cover door
and rotate the fuse-pull lever to remove the
fuse. Remove the small printed circuit board
and select the operating voltage by orienting
the printed circuit board to position the
desired voltage to be visible when pushed
firmly into its slot. Rotate the fuse-pull lever
back into its normal position and insert the
correct fuse into the fuse holder.
Line Fuse
Verify that the correct line fuse is installed
before connecting the line cord. For 100
V/120 V, use an 1 Amp fuse and for 220
V/240 V, use a 1/2 Amp fuse.
Line Cord
The FS700 has a detachable, three-wire power
cord for connection to the power source and to a
protective ground. The exposed metal parts of
the instrument are connected to the outlet ground
to protect against electrical shock. Always use an
outlet which has a properly connected protective
ground.
Antenna
The FS700's vertical antenna should be installed
on the roof of a building. Watch for power lines
when installing the antenna.
