maintenance of equipment, consult the supplied PC manuals.
How to Clean the Diskette Drive
Like the more familiar magnetic read and write heads in tape recorders and VCRs, diskette
drive heads benefit from periodic cleaning. Just how often you require to clean the diskette
drive heads at your site depends on how much you use the diskette drive(s). This will vary
from site to site. Many sites will not use the diskette drive at all for day-to-day operation.
Others may choose to store reports, such as shift-break reports, in diskette files. If your site has
a hard-disk drive, then you probably will not use the diskette drive very often.
If you use a diskette drive three or four times a day, you must probably clean the heads every
six months. In any case you must clean the diskette heads once a year whether or not the drives
have been used. This removes any accumulated dust.
Special diskette drive cleaning kits are available from Gasboy and other vendors, and must be
used to clean the diskette drive on the Site Controller. A kit is available for the 3.5-inch drive.
When Batteries Fail
If your Site Controller logs the message Battery X failed, it means that battery number X, used
to back up RAM memory, has failed. There are two coin batteries that maintain the memory
when AC power fails. A red light on the SC III memory PCB indicates that one of the batteries
is bad. Close S2 position 2 and open position 1 to switch to battery 2. When any one battery
must maintain the memory without AC power for a short period of time, you must replace a
battery as soon as it goes bad.
Do not turn off power to the Site Controller if this message has occurred, or memory may be
lost.
Island Card Reader
How to Clean the Magnetic Strip Reader
If your system reads magnetic cards in one or more island card readers or consoles, then you
require to clean the magnetic strip reader units periodically. A magnetic strip reader that
requires cleaning has a harder time reading cards, requiring several passes to read some cards.
How often magnetic strip readers require to be cleaned depends on how often they are used
and also the type of environment. Generally, island card readers require to be cleaned about
once a month, but island card readers with many diesel fuel transactions may require to be
cleaned weekly.
