STOP
Once logging is started, it will continue until the
STOP
key is pressed, the unit is
deliberately turned “OFF”, or the batteries are exhausted. The OM-550 can also be
programmed to automatically stop logging when the data cache if full.
To stop logging, first ensure that the unit is “awake”, then press the
STOP
key. (If the
unit is in Power save mode, press
ON
and then the
STOP
key instead.) The unit will
complete the current scan but logging is now disabled and the Statistics will be printed.
••
PROG/EXIT
This key toggles the OM-550 in and out of the Program mode.
Pressing the
PROG
key enters the Program mode and will erase the data cache and
print a complete description of its current programming. The Activity LED double-blinks
and the horn double-beeps to signal that the unit is in Program mode. Refer to section
4.0 PROGRAMMING
for more information.
Pressing the
EXIT
key accepts all existing programming and returns the unit to a ready
state. Incomplete keyboard entries (part of a new date, for example) are rejected and
the Activity LED and horn return to a single beep/blink.
••
OK
The
OK
key is used only during programming. Use it to accept the current item, as is
without changing. This function skips quickly down through the programming menu to
reach a particular item to be reprogrammed. All accepted items are printed, as
confirmation. Refer to section
4.0 PROGRAMMING
for more information.
