AC PowerSources
Computers are sensitive to fluctuations in the powersupply at the wall socket. This
is rarely a problem unless you are operating in the vicinity
of
heavy electrical
machinery. Thepowersource may also be unstable
if
some appliance or office
machine in the vicinity has a defective switch which arcs when turned on oroff.
YourModel III
TRS-80 is equipped with a specially designed, built-in AC line filter.
It should eliminate the effects
of
ordinary power-line fluctuations.
However,
if
the fluctuations are severe, you may need to take some
or
all
of
the
following steps:
• Install bypass
or
isolation devices in the problem-causing devices
• Fix
or
replace any defective (arcing) switches
• Install a separate power-line for the Computer
• Install a special line filter designed for computers and other sensitive electronic
equipment
Powerline problems are rare and many times can be prevented by properchoice
of
installation location.
The
more complex the system and the more serious the
application, the moreconsideration you should give to providing an ideal power
source for your Computer.
Maintenance
YourComputerrequires little maintenance.
It's
a good ideato keep it clean and free
of
dustbuild-up. This is especially important for the keyboard. Radio Shack sells a
custom-designed Model III dustcover you may find helpful.
If
you need to cleanthe Computercase, use a damp, lint-free cloth.
Theperipheral devices (cassette recorder, line printer, etc.) may require more
maintenance. Checkthe
owner's
manual for each peripheral in your system.
