(C) Change:

This symbol appears whenever the change due amount is dis­played.

(L) Low battery:

This symbol appears when the power of the installed batteries is
below a certain level or you need to replace the batteries with
new ones. (see the "Maintenance" section for explanation.)

(L) No battery:

This symbol appears when no batteries are installed. (see "Main­tenance" and "Getting Started" sections for explanation.)

8.BATTERY

2)LOW BATTERY

Low battery indication will appear on the left side of display when the
battery voltage is low.

CASE 1:When sitting idle or after completion of transaction.
The machine can indicate the low battery condition (Always)
CASE 2:Low battery indication will not appear during key opera-

tions, but will appear after power up of the cash register.

[Display sample]

" 0.00": Battery is OK.
"L 0.00": Low battery (You have to change the batteries.)

After finalization
"F 12.34": Battery is OK.
"L 12.34": Low battery ("L" indicate instead of "F".)

3)NO BATTERY

If the user forgets to replace the battery and the battery voltage falls
below a certain level, or if a power failure occurs with no batteries
installed, the memory contents cannot be retained. The CPU judges it
as no battery and performs the master reset. In this case, all the
settings and registrations are cleared. If, however, the power is con­tinuously supplied to the AC cord, the memory contents are retained.

Low battery:Batteries are installed, but the voltage is low.

Memory back up can be done.

No battery :Batteries are not installed or the voltage is extremely

low.
The master reset is executed when a power failure
occurs, when the batteries are not properly charged.

Low battery & No battery indication will appear at the most left posi­tion of display when the battery voltage is low.

CASE 1:When any numeric entry & item entry is not done or just

after finalization.
The machine can indicate the battery condition. (Always)
CASE 2:When numeric entry or item entry is done.

Battery condition is not appeared.
Exceptionally, at the power is restored after power failure, the
low battery & No battery indication will appear on the display
only when the battery voltage is low.
And the indication will disappear after any key entry.

[Display sample]

" 0.00": Battery is OK.
"L0.00": Low battery
"L0.00": No battery
After finalization

"F12.34": Battery is OK.
"L12.34": Low battery ("L" indicate instead of "F".)
"L12.34": No battery ("L" indicate instead of "F".)

1)MEMORY BACK UP BATTERY

When the master rest is completed, the buzzer sounds interm ittently

three times.

5. Attach the memory back up battery to the ECR.
The master reset can also be accomplished in the following case.

(See Note 3.)
Note 1) Power OFF: Means disconnecting the AC power supply to

the machine.
(Specifically, unplugging the machine.)

Note 2) Power ON: Means connecting the AC power to the ma-

chine.
