MENU Key
The MENU key has three functions.
•
First, when the system is presenting the normal display, pressing the MENU key will cause the system to
shift to the Configuration Menu.
•
The second function of the MENU key is to return to the next-higher menu level, e.g. from the sensor
configuration menu to the system menu, or from the system menu out to normal mode. If in the middle of
entering a multi-digit parameter, the MENU key also cancels any changes to the parameter. When the
MENU key is used to return to normal mode, any changed configuration parameters are saved in the DVP-
120C’s memory.
•
The third function of the MENU key is to change the LCD contrast by holding the MENU key for five (5)
seconds, at which point the LCD will prompt for further activities, see sections 4.4 for more detail.

devices). Pressing and releasing the button will silence the internal buzzer. The HUSH button must be held for 3
seconds to silence the Horn and Strobe devices.
