Master reset: Clears all the memory and initializes each preset parameter
1. Turn off the power (Power OFF).
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). When the master rest is completed, the buzzer sounds intermittently three times.

4. Turn on the power (Power ON). 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.
Power OFF: Means disconnecting the AC power supply to the machine. (Specifically, unplugging the machine.)
Power ON: Means connecting the AC power to the ma-chine. (Specifically, plugging in the machine.)
[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.]

Perform the keyboard check with the
sum check data of the key code.
Enter the sum check data of each model in the four digits preceding the diag number 02, and compare the data with the key position code which is added until the “CA/AT/NS” key is pressed.
If the data coincides with the code, the completion print is performed.
If not, the error print is performed.
