The Anritsu MS2085A/89A Site Master is capable of approximately three hours of continuous operation from a fully charged, field-replaceable battery (refer to Battery Information). The instrument can also be operated from a 15 VDC source (which will simultaneously charge the battery). This can be achieved with either the Anritsu AC-DC adapter or the automotive power adapter, which can be purchased as an optional accessory. Refer to the instrument Technical Data Sheet for more options and accessories. The instrument can also be charged for up to six hours using an Extended Power Pack that is sold separately.
Caution
When using the Automotive Power Adapter, always verify that the supply is rated for a minimum of 75 watts @ 15 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, briefly press the power button on the top right of the top connector panel (see Figure: Top Connector Panel).
The Site Master takes approximately 80 seconds to complete power-up and to load the instrument software. At the completion of this process, the instrument is ready for use.
Note
Keep the fan inlet and exhaust ports clear of obstructions at all times for proper ventilation and cooling of the instrument.
Power/Charge LED Indicators
The power/charge LED is integrated with the power button. The LED has the following indicators:
• Solid purple when the instrument is on or booting up.
• Solid red when the instrument is off and connected to an external power source.
Shutting Down and Restarting
To shut down or restart the instrument, briefly press the power button (a shutdown dialog will be displayed), then select RESTART INSTRUMENT or POWER OFF. The current setup is saved when the instrument is shut down or is restarted. Once the instrument shuts down, it will either power off completely (if running on batteries) or it will go into a low power state (if running on external power).
