CHAPTER 1. GENERAL

This manual describes the ER-A440 disassembly procedures and the option attachment procedures. For assembly procedures, reverse the disassembly procedures. For attachment of options which do not re- quire special descriptions, descriptions are omitted.

Note for operations

•Before operation, ground the operator’s body and perform other necessary measure against static electricity.

2. Master reset (All memory clear)

There are two possible methods to perform a master reset.

•MRS-1

Used to clear all memory contents and return machine back to its initial settings and return keyboard back to default keyboard layout.

Procedure

•MRS-2

Used to clear all memory and keyboard contents.

This reset returns all programming back to defaults. The keyboard must be entered by hand.

This reset is used if an application needs different keyboard layout other than that supplied by a normal MRS-1.

Procedure

1)Unplug the AC cord from the wall outlet.

2)Set the MODE switch to the (SRV′) position.

3)Plug in the AC cord to the wall outlet.

4)While holding down JOURNAL FEED key and RECEIPT FEED key, turn to (SRV) position from (SRV′) position.

5)Key position assignment:

After the execution of MRS-2, only the RECEIPT FEED and JOURNAL FEED keys can remain effective on key assignment. Any key can be assigned on any key position on the main key- board.
