MASTER RESET and program reset

1 – 1

Master resetting clears the entire memory and resumes initial values.

Master resetting can be accomplished by using the following procedure:

Procedure :

1) Unplug the AC cord from the wall outlet, or set the mode switch to OFF position.

2) Let the ECR be witout the memory backup battery.

3) Wait over 1 minute for discharging.

4) Set the mode switch to any position except OFF.

5) Plugin the AC cord to the wall outlet, or turn the mode switch from OFF position to another position.

6) Insert batteries before carrying out operation after master resetting.

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 memories are lost and the machine does not work properly
after power recovery; this requires the master reset operation.)

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) Wait over 1 minute for discharging.

3) Set the mode switch to the PGM position.

4) While holding down the 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.
