> Turning On the Site Master
> The Anritsu Site Master S331L is capable of approximately eight hours of continuous operation from a fully charged battery.
> The Site Master can also be operated from a 12 VDC source (which will also simultaneously charge the battery). This can be achieved with either the Anritsu AC-DC Adapter or the Automotive Cigarette Lighter Adapter.

> Caution | When using the Automotive Cigarette Lighter Adapter, always verify that the supply is rated for a minimum of 40 Watts @ 12 VDC, and that the socket is clear of any dirt or debris. If the adapter plug becomes hot to the touch during operation, discontinue use immediately.

> To turn on the Site Master, press the green On/Off button on the front panel (Figure: Site Master Instrument Overview (1 of 2)). The Site Master takes approximately 90 seconds to complete initial power up and load the application software.
> Momentarily pressing the On/Off button when the Site Master is operating will place the instrument into standby mode. A message “Going into Standby Mode” will be displayed and the touchscreen display will turn off. The green power LED will slowly pulse when the instrument is in standby mode. Press the On/Off button momentarily again to restore the instrument to standard operation.
> 5 minutes of inactivity will cause the Site Master to enter reduced power mode. The display screen brightness is reduced and the keypad backlighting is switched off. Touching any portion of the screen or any keypad press while in reduced power mode will instantly restore screen brightness and keypad backlighting.
> Press and hold the On/Off button for a few seconds to completely shut down the Site Master. The current settings will be saved and a shutdown message will be displayed before the instrument turns off.

> Note | If the instrument appears non-responsive or will not power down using the standard shutdown procedure, disconnect the external power supply, then press and hold the power button for 10 to 15 seconds to force an instrument shutdown. The current settings will not be saved.
