[MASTER RESET PROCEDURE]
Master resetting 1 and 2 can be accomplished by using the following
procedures.
There are two possible methods to perform a master reset.
• MRS-1
Procedure :
Clears the entire memory and resumes initial values.
1) Power is on (Insert the plug into the outlet)
2) Push the reset switch
3) Depress the RECEIPT key with pushing the reset switch
4) Release the reset switch
5) Operate by following key sequence
a
3b3c3d
• MRS-2
Clears the entire memory and resumes initial values. (Master resetting
2 enables the layout of fixed keys in addition to master resetting 1.)
Procedure :
1) Power is on (Insert the plug into the outlet)
2) Push the reset switch
3) Depress the RECEIPT and “A” key with pushing the reset switch
4) Release the reset switch
5) Operate by following key sequence (Secret key operation)
a
3b3c3d
Program the 0 to 9 keys, 00 key, decimal point key, X key, SBTL key,
MODE key, cursor keys, HOME key, and CANCEL key, CL key and
ENTER key and TL key in this sequence.
(This means that the key first pressed is programmed as the 0 key, the
key pressed second as 1 key ---- and the last key pressed as the TL
key.)
To inhibit a particular key, press the 0 key at the point when that key
should be programmed.

MASTER RESET AND PROGRAM RESET
1 – 2
2. PROGRAM RESETTING (INITIALIZATION)
1) Power is off (power plug is pulled out)
2) Push the reset switch
3) Insert the power plug into the outlet with pushing the reset switch
4) Release the reset switch
This resetting resumes the initial program without clearing memory.
Note:
When power is on, the reset switch is operated.
Then there is possibility to break RAM data.
So, in Program reset, power plug is pulled out first.
And it is also the same for master reset.
But in master reset, RAM will be clear.
And we think it is not problem to break RAM data by operating the
reset switch when power is on for master reset.
