The System Menu includes global system settings such as the date, time, and password as well as hardware-specific settings such as the front panel brightness, contrast-, and screensaver controls.

Time Zone
When Network Time Protocol (NTP) is enabled, the Time Zone control selects a specific time offset for your location. Four specific U.S. time zones (with and without Daylight Savings Time) are included along with all internationally-supported offsets from Greenwich Mean Time (GMT).

Time and Date
The current time and date can be set manually when NTP is not used. The left/right arrows change the field while the up/down arrows change the value.

Note - Having an accurate clock is important when using PDM II's PD-Alert function which uses date and time stamps to identify events and audio log files.
Time Format
Time format toggles between 12-hour (with AM/PM designations) and 24-hour ("military time") formats.

Password
The Password menu allows you to set and change the password required to access the web-based remote control. The PDM II ships with no default password. You must set a password via the front panel in order to access the unit remotely. The left/right arrows change the field while the up/down arrows change the value. Valid characters include upper and lower case letters, numbers, and space between characters. Note that spaces at the end of a character string are automatically removed.

If there is no password, the display will show a flashing "Web UI Disabled" message.
Note - PDM II passwords are designed to prevent unauthorized access via the remote network interface and are visible from the front panel.
Brightness
The Brightness control adjusts the overall brightness of the front panel LCD.

Screen Saver
The Screen Saver control determines the length of time the front panel display stays on after the most recent button press, from 1 to 100 minutes. Setting it to "Never" will keep the display on continually, although this is not recommended due to the finite life of the LCD backlight.
