set using the joystick
UP and DN positions and are accepted by pressing the
joystick equivalent of an ENT button.

In order to get access to “Change Program Protection (PP) Password”
menu, Program Protection must be disabled. If PP password is set to Zero
(Disabled), entering PP Password is not required and PP can be disabled
from “Program Protection” menu (see
Figure 9 ). If PP Password is set to
any value more than Zero, the firmware will prompt with “Enter Program
Protection Password” (see
Figure 10 ). The user must enter a program
protection code (up to 3 digits). If the PP password is lost or forgotten,
contact the factory or your distributor.
Once the “Change PP Password” menu is selected, the following screen will appear:

Program Protection (PP) password set to Zero (PP Disabled).
