A number of selected problems that could arise when using MT9750 are listed below:
Password entry in conjunction with MT9750 and AVAS
In the AVAS product, entry of a password is required in the “NETPASSWORD” field in the “AVM$N001” screen.
Character set size not optimum for print output
If a line on the screen is output in two print lines in a hard copy, the pre-assigned character set size has been changed. If the default size is changed, taking into account the layout an automatic line feed is created if the right-hand margin is exceeded.
To undo this, you must set suitable values for the character set, font height, and font width under Configuration > Peripherals > Local Printer > Print Layout in the menu.
Entry using numerical keypad does not work
Make sure the numerical keypad is activated. Most keyboards indicate that numerical keypad entry is activated by a small, illuminated
[1]character. If necessary press the[Num]key on the numerical keypad to activate entry.
