• Standard equipment:
• Max. number of drawers: 1
• The drawer consists of:
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 operations, but will appear after power up of the cash register.
(1) Drawer box (outer case) and drawer
(2) Money case
(3) Coin case
(4) Lock (attached to the drawer)
[Display sample]

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)

3) LOCK (LOCK KEY : LKGIM7331BHZZ)
• Location of the lock: Front
• Method of locking and unlocking:
• Key No:
To lock, insert the drawer lock key into the
lock and turn it 90 degrees counter clockwise.
To unlock, insert the drawer lock key and turn

8. BATTERY
1) MEMORY BACK UP BATTERY
For memory back up, the dry battery ULM-3 (3 pieces) are needed.
1. Memory holding time:
Approx. 1 year after New dry batteries are installed.
2. Battery exchange method:
When the low battery symbol "L" lights up, replace the batteries (3
AA) replaced by the following method;
1) Power on the ECR.
2) Mode switch turn to "REG" mode.
3) Remove the OLD dry batteries (3 pieces).
4) Insert the NEW dry batteries (3 pieces).
5) Confirm the low battery symbol "L" is off.
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.
"L 0.00" : Low battery
"L 0.00" : No battery
After finalization
"F 12.34" : Battery is OK.
"L 12.34" : Low battery ("L" indicate instead of "F".)
"L 12.34" : No battery ("L" indicate instead of "F".)

CHAPTER 3. MASTER RESET
Master reset: Clears all the memory and initializes each preset parameter.
The master reset should be performed by using the following procedure.
1. Turn off the power (Power OFF). (See Note 1.)
2. Let the ECR be without the memory back up battery.
3. Turn the mode switch to the others of Power-off position.
4. Turn on the power (Power ON). (See Note 2.)
When the master rest is completed, the buzzer sounds intermittently
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 machine.
(Specifically, plugging in the machine.)
Note 3) In case a power failure occurs when the machine has no
battery installed, the master reset operation is automatically
performed after the power has been restored.
