This 'sign-on' message appears when you apply power to the PK-88, or when you issue
the
RESTART
and
RESET
commands. The release date will change in each new firmware
release. The checksum is a hexadecimal number that verifies the firmware version you are
using is working.
PK-88 is using default values.
This message appears with the sign-on message shown above if the batteries are not in-
stalled (or have failed). You will see this message the first time you apply power to the
PK-88. This message also appears if the PK-88 loads the defaults in response to the
RE-
SET
command, or when the firmware version is changed.

mand Mode. The front panel 'CMD' LED also indicates if the PK-88 is in Command
Mode.
