MASTER RESET AND PROGRAM XE-A40S [1] MASTER RESETTING Master resetting clears the entire memory and resumes default values. Master resetting can be accomplished by using the following procedure: Procedure A: 1) 2) 3) Unplug the AC cord from the wall outlet. Set the mode switch to the PGM position. While holding down both the JOURNAL FEED key and [CL] key, plugin the AC cord to the wall outlet. 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 memory will be lost and the machine does not work properly after power recovery; this requires the master reset operation.) [2] PROGRAM RESETTING (INITIALIZATION) This resetting resumes the initial program without clearing memory. This resetting can be operated at below sequence in PGM mode. Procedure: 1) 2) 3) Unplug the AC cord from the wall outlet. Set the mode switch to the PGM position. While holding down both JOURNAL FEED key and RECEIPT 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. 3–1 XE-A40S CHAPTER 4.

The program on EP-ROM is transferred to flash ROM by switching the banks through S-RAM. The RESET signal is generated when: 1) The mode key switch is turned from SRV to a position other than SRV'(excluding OFF). 2) The power is turned ON more than 10 seconds after the power is turned OFF. (The reset signal may not be issued if the POWEROFF time is short.) [8] DRAWER The XE-A40S has a 1 drawer port. (No open sensor is provided.) 3) The mode key switch is turned from OFF to a position other than OF (excluding the SRV position).
