To initialize the cash register
1. Set the mode switch to OFF.
2. Plug the power cord of the cash register into an AC outlet.
3. Load the memory protection batteries.
4. Set the mode switch to REG.
To load the memory protection batteries
1. Remove the printer cover.
2. Open the battery compartment cover.
3. Load 3 new UM-3, R6P (SUM-3) or LR6 (AM-3) type batteries into the compartment.
Be sure that the plus (+) and minus (–) ends of each battery are facing in the directions indicated by
the illustrations inside the battery compartment.
4. Slide the memory protection battery compartment cover back into place.
5. Replace the printer paper and printer cover.
REPLACE MEMORY PROTECTION BATTERIES AT LEAST ONCE EVERY YEAR.
2-2. To select the date format and monetary mode (130CR only)
You can select the date format and the monetary mode after initialization depending on the requirements in your
area.
Default date format is Day/Month/Year.
Default Monetary Mode is Add 2.
Example: Change the date format to Month/Day/Year, and the monetary mode to Add 0.
1. Set the mode switch to PGM.
2. Press the following keys.

Notes
1. When the P07/XT1 pin is used as an input port, set bit 6 (FRC) of the processor clock control register
(PCC) to 1 (do not use the feedback resistor incorporated in the subsystem clock oscillator).
2. When pins P10/ANI0 to P17/ANI7 are used as an analog input of the A/D converter, set port 1 to the
input mode. In this case, any connected on-chip pull-up resistors are automatically disabled.

6. DIAGNOSTIC OPERATION
To start the diagnostic program
ECR enters the diagnostic mode by the following operation.
1Turn the mode key to PGM.
2Input “99990000” and “ST(SUB TOTAL)”.
Upon the above operation ECR prints the following and issues a receipt.
* Note that the test mode will not boot if once a receipt has been issued in the REG/RF/X/Z mode.
In this case, remove the battery and perform the above operation again.
