4.2.24 ACCESSING THE INITIAL SETTING PROCEDURE (Page 4-15)
When the machine is switched on for the first time after installation, an initial setting
procedure appears. With this procedure, the user can program the initial setting items
more easily. However, the initial setting procedure does not appear again.
If you need to use the initial setting procedure again but do not need to display the
country code any more, do the following.
1. Set System Switch 15 bit 3 to 0, so that the user cannot change the country code.
2. Press the resolution key, !key, and "key all at the
same time.
3. After the display shows “Programmed”, turn off the
machine.
Then the machine will show the initial setting procedure when the machine is turned on
again.
If you need to use the initial setting procedure again and also need to display the
country code, do the following.
CAUTION: THIS PROCEDURE WILL ERASE ALL RAM DATA.
1. Press the resolution key, !key and #key all at the
same time.

This country code determines the factory
settings of bit switches and RAM addresses.
However, it has no effect on the NCU
parameter settings and communication
parameter RAM addresses.
Cross-reference
NCU country code: Function 08, parameter
CC.
The bit switch country code will
automatically be changed to the same
country code with the NCU country code
when you change the NCU country code
and exit the service mode.
Note: If RAM reset level 1 is done, this bit
switch resets to 02 (UK).
