WARNINGS AND CAUTIONS
You
should
observe
several
precautions
when
han-
dling this equipment.
WARNING
This unit is designed to be oper-
ated with a
ground
connection to
the chassis
via
a three-wire power
connection.
If the unit is
not
prop-
erly grounded while operating from
an ac power
source,
the voltage
potential
between
it and ground
may cause an electrical
shock.
WARNING
This
system's
Processor board uses
a lithium battery as a memory
keep-alive voltage
source.
Do not
mutilate or disassemble the bat-
tery
cell.
The
lithium
metal is a very
active material that burns
in
the
presence of water
or
high humid-
ity. Do not put the battery in fire
,
attempt to charge it, heat it above
100°C,
or solder
directly to
the cell.
Do not
overdischarge
the cell to a
reverse voltage
greater than
3V:
the
battery may burst and burn or
release
hazardous materials.
(See
Section
4,
