12.2 Altering the main programming enable

The main programming enable can only be altered when switching on the HDA 5500. If the

HDA 5500 is already in operation, then the supply voltage must first be switched off or the

HDA 5500 must be disconnected from the supply voltage.

Procedure:

• When switched off, press both arrow keys simultaneously and hold down.

• Switch on or connect the supply voltage and at the same time continue to hold down the

arrow keys for at least 3 s.

• MPrG (Main Programming) is displayed.

• After approximately 2 s the display changes and the actual setting is displayed:

Free (programming enabled) or Loc (programming disabled).

• Within approximately 3 s the setting can be changed to Loc or Free by pressing

the

or key.

• If

or have not been pressed for approximately 3 s or longer, then the displayed

setting is accepted. If a setting has been changed, then ProG (Programming) is dis-

played for approximately 2 s. This means the changed setting is stored in the HDA 5500.

Afterwards the display returns to normal operation.
