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
need 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 should probably clean
the heads every six months. In any case you should 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 should 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. While any one battery should
maintain the memory without AC power for a short period of time, you should
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.
