You should save all source documents or
transactions entered in the ROM until you have
a successful backup at the end of the day, at which
time they can be filed. If there is no source
document, you should keep a list of transactions.
If, for any reason, the ROM system cannot be
used, you should save all data until the system
is back on line and reenter it at that time. Upon
completion of ROM processing, you must exit the
system so someone without authority won’t have
access to the system by using your security access.
Logging Off the ROM System
Once you have completed your functions on
the ROM, you will have to log off the system. To
log off the system, depress Esc until the ROM
master menu is displayed. Then enter 16 and
depress RETURN/ENTER. If you are using the
Zenith Z-248, enter the word ship then Y to
position the read/write heads on the hard disk to
a safe location. If you are using Honeywell AP,
enter PARKAP, then depress any key other than
ENTER to park the heads. Depress the ON/OFF
power switches of the monitor and terminal. Then
turn the printer switch to the OFF position.
Maintaining the ROM System
The maintenance of the ROM system should
be done by qualified technicians only. Any
problems that cannot be resolved by the ROM
user should be referred to the ship’s store officer
for action. The ROM system itself does not
require a lot of maintenance. The most common
problem you will have with the ROM system is
dust which builds up over a period of time when
the computer is not cleaned. To cut down on dust
