# System Menu

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]
> **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.

![Figure 3- Time format screen](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/screen(8)(1)(1).png?sv=2026-02-06&spr=https&st=2026-11-07T17%3A54%3A21Z&se=2026-11-07T18%3A54%3A21Z&sr=c&sp=r&sig=3z2ZvOSwk4OkvLcZVYx3zyWzyfmgb1rXUGcwbmeJamU%3D)

### 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.

![Figure 4 - Password screen](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/screen(8)(1)(1)(1)(1)(1).png?sv=2026-02-06&spr=https&st=2026-11-07T17%3A54%3A21Z&se=2026-11-07T18%3A54%3A21Z&sr=c&sp=r&sig=3z2ZvOSwk4OkvLcZVYx3zyWzyfmgb1rXUGcwbmeJamU%3D)

If there is no password, the display will show a flashing "Web UI Disabled" message.

> [!NOTE]
> **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.

### Contrast

The Contrast control adjusts the contrast- of the front panel LCD.

![Figure 6- Contrast screen](https://cdn.document360.io/57e3cd80-d493-453c-9672-ad1b043dadc3/Images/Documentation/screen(8)(1)(1)(1).png?sv=2026-02-06&spr=https&st=2026-11-07T17%3A54%3A21Z&se=2026-11-07T18%3A54%3A21Z&sr=c&sp=r&sig=3z2ZvOSwk4OkvLcZVYx3zyWzyfmgb1rXUGcwbmeJamU%3D)

### 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.
