In "adjustment item display", the items pointed by cursor can be changed using VOL UP/DOWN key.(Holding
down the key is effective.)
For the items in "LCD DATA", select the item and hit ENTER key.  The ten's digit (leftmost digit) in the address
changes to red (others in green).  Data change using VOL UP/DOWN key is enabled.
To move to the next digit, press CH UP key (or rightward cursor key).  To go back to the previous digit, press CH
DOWN key (or leftward cursor key).  Thus, 4 digits data can be entered.
When CH UP key is pressed while in rightmost digit, the cursor moves to the leftmost digit.  When CH DOWN key
is pressed while in leftmost digit, the cursor moves to the rightmost digit.
After address data adjustment, press ENTER key to exit from 4-digit adjustment and change the entire "LCD
DATA" line to red letters.  (Same status as item selection)
