is facing up (so you can see it).

5. Replace the back-up battery holder and secure it by tightening its screw.

• Be careful that you do not over tighten the screw.

6. Replace the battery compartment cover.

RESET OPERATION

You can use either SECRET RESET or ALL RESET to initialize the NX Unit. ALL RESET deletes all data stored
in memory, while SECRET RESET deletes only the data stored in the secret drawer.

To perform ALL RESET

1. Switch power ON.

2. Open the battery compartment cover.

3. Press the RESET button with a thin, pointed object.

• At this time, the touch panel screen appears.

4. Tap the tip of the pencil icon as each one appears.

• When you tap the fourth pencil icon, the RESET screen appears.

Warning!

The next step deletes all data stored in the NX Unit's memory. Make sure that you really want to delete the
data before you continue!

5. Tap ALL RESET.

Note

• The message “ALL RESET? OK/ESC” always appears in English, regardless of the system language

setting.

6. Tap OK to reset the memory and delete all data or ESC to abort the reset operation without deleting
anything.

• After you tap OK, the system language screen appears.

7. Select the system language by tapping on the language you want to use, and then tap OK.

• After you select the system language, the Home Time screen appears.

8. Check the Home Time setting and make any changes that you want.

TO SAVE THE DATA TO ANOTHER UNIT

NX-4000/6000 can transfer customer's data to another NX-4000/6000 with memory protection only when
replacing the LCD or the outer case.

How to transfer the data

1) Make sure that the power of both units is switched off.

2) Remove the covers from the data communications jacks on the two NX units.

3) Connect the two units using the SB-62 cable as shown in the figure below.

4) Turn the power switch of slave units on.

5) Reset the slave unit.

6) The slave unit must be set the date of Feb. 3rd, 1901 into the memory under the calculator mode.
Operation : ON AC 1 DATE 2 DATE 3 DATE M+

If you don't set the date, the "PASSWORD" isn't transferred to the slave unit.

7) Check the hardware parameters, and if the both units have another condition, reset as follows;
Operation : MENU FUNC DATA COM. SET UP PAR. NONE 7 9600 OK

TOUCH PANEL CIRCUIT

Four electrodes are installed in top and bottom right and left of panel, and the touch panel recognizes the
coordinate which was pushed with a pen on panel by detecting change volume of current which flowed through
panel by pushing panel.

Circuit Operation

TXL and TYU of drive signals are sent through LS240 from CPU by X1,Y1 of touch panel when turn on power
supply. And, TXR,TYD signals are output through LS240 from touch panel to AIN terminal of A/D converter
TC35093, and convert the analog value into digital value, and TC35093 outputs digital data DB0~DB7 of 8 bits
to CPU.

TC35093 changes TXR of X axis signal, TYD of Y axis signal in alternating by analog switch 4066 by ADCH
signal from CPU to output digital data, and input analog data into AIN terminal of TC35093.

Synchronize analog data input from AIN terminal in clock signal of 1 pin, and TC35093 outputs digital data
DB0~DB7 to CPU when OE and STC signal input become H.
