The number of repeats is displayed, starting at "2" and incremental
with each repeat. When you have registered ten times, the display
will show "0" (2→3......9→0→1→2...)
• Sentinel mark
When amount in the drawer reaches the amount you preprogrammed, the sentinel mark "X" is displayed to advise you to
remove the money and put it in a safe place.
• Power save mark
When the cash register goes into the power save mode, the power
save mark (decimal point) lights up.
• Function message display area
Item labels of departments and PLU/subdepartments and function
texts you use, such as %1, (-) and CASH are displayed.
When an amount is to be entered or entered, "AMOUNT" is displayed: When an amount is to be entered, ------- is displayed at the
numeric entry area with "AMOUNT". When a preset price has been
set, the price is displayed at the numeric entry area with
"AMOUNT".
• Numeric entry display area
Numbers entered using numeric keys are displayed here.
* Date and time display
Date and time appear on the display in the OP X/Z, REG, or MGR

CHAPTER 3. MASTER RESET AND PROGRAM RESET
Service Manual
[1] MASTER RESETTING
Master resetting clears the entire memory and resumes default values.
Master resetting can be accomplished by using the following procedure:
Procedure A: 1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both the JOURNAL FEED key
and [CL] key, plugin the AC cord to the wall outlet.
The master reset can also be accomplished in the following case.
In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed
after the power has been restored.
(This is because if power failure occurs with no battery attached to the
machine, all the memory will be lost and the machine does not work
properly after power recovery; this requires the master reset operation.)
[2] PROGRAM RESETTING (INITIALIZATION)
This resetting resumes the initial program without clearing memory.
This resetting can be operated at below sequence in PGM mode.
Procedure:1) Unplug the AC cord from the wall outlet.
2) Set the mode switch to the PGM position.
3) While holding down both JOURNAL FEED key
and RECEIPT FEED key, plugin the AC cord to
the wall outlet.
NOTE: In case power failure occurs when the machine has no battery
attached to it, the master reset operation is automatically performed after the power has been restored.
