3 3.1 Using the Base Station Introduction The Base Station is the display unit in the DoseAware System. It communicates wireless with PDMs within radio range in order to collect, present and store PDM dose data.
Getting started 3.2 3.2.1 Getting started Starting the wall mounted Base Station 1 Connect the output connector of the power adaptor to the back of the Base Station, if needed. 2 Connect the input connector to an AC electrical outlet socket. The Base Station screen is a touch screen. Operate the Base Station by tapping buttons and graphs on the screen. NOTE WARNINGS PDMs are shown on a first come first serve principle (see “reserved slots menu” in section “Admin Settings menu” on page 3-12).
Base Station features 3.2.2 3.3 Starting the MCS mounted Base Station 1 Switch on the X-ray system and the Base Station will automatically switch on. First a Philips start up screen will be displayed for a few seconds and after 30 seconds the system is ready to use. The Online View will display a maximum of 8 PDMs at a time. Only PDMs that are in range of the Base Station will be displayed. The Base Station screen is a touch screen. Operate the Base Station by tapping buttons and graphs on the screen.
Base Station features • A Walk-Up View (see section “Walk-Up view – view detailed dose data ” on page 3-7 ) where you can view historical dose data for a PDM chosen from the OnLine View. • A Base Station Settings View (see section “Base Station Settings view” on page 3-11 ) for administrator settings. NOTE Online view – view current dose rates 9896 002 16623 3.3.1 When the Base Station memory is full, the oldest data will be overwritten with newer data.
Base Station features 3.3 The Online View displays the current personal dose rates and peak dose rate indicators, for up to 8 PDMs within range of the Base Station. NOTE PDMs are shown on a first come first serve principle (see “reserved slots menu” in section “Admin Settings menu” on page 3-12). PDMs that are not shown in the Online View still measure and store dose data.
Base Station features The| Displayed Name| button identifies the PDMs. It may be truncated on the button due to lack of space. When a PDM moves out of range of the Base Station, its button will remain visible in the Online View for two minutes. The button will then remain grayed out for another eight minutes before it disappears. This feature allows people to temporarily leave the room without loosing their position in the list. When a button is grayed out, it is not possible to access the Walk-Up View.
Base Station features 3.3.2 3.3 Walk-Up view – view detailed dose data Figure 3.3 Personal Dose Meter Information panel Enter the Walk-Up View of a PDM by tapping the |Displayed Name| button of that PDM in the Online View. On the left hand side of the WalkUp View a Personal Dose Meter Info panel is displayed (see figure above).
Base Station features The Walk-Up View also consists of the Personal Dose Overview (see section “Personal Dose Overview” on page 3-8), which is the default WalkUp view. It has two sub views: • the Annual Personal Dose view (see section “Annual Personal Dose” on page 3-9) • the Personal Dose History view (see section “Personal Dose History” on page 3-10) 9896 002 16623 0900a44780045a3a Personal Dose Overview Figure 3.
Base Station features 3.3 last Dose Session reset, measured in Sv. Use the reset buttons (2) to reset a Dose Session to zero. Information about dose session reset will appear as an event in Dose Manager. • Total Personal Dose since the last Dose History reset. • The current day’s Personal Dose History graph. You can also access the Personal Dose History sub view (3), see section “Personal Dose History” on page 3-10.
Base Station features • The annual dose limit distributed over the full year (dashed line). As long as the accumulated dose stays below this value, the annual dose limit will not be exceeded for the full year. • Accumulated dose in relation to the annual dose limit for the current year (blue/orange line). When the accumulated dose exceeds the distributed annual dose limit, the color will change from blue to orange in order to alert the user to take actions.
Base Station features 3.3 In the Day/Week time spans you can view accumulated dose value bars. Each bar represents the accumulated dose during one/four hours, respectively. Within the Day and Week time spans, tapping a dose bar in the diagram will zoom into the larger underlying time scale (that is Week -> Day and Day -> Hour). Within each time span (Hour/Day/Week) you can step forward and backward in time with the arrow buttons on the bottom of the screen.
Base Station features 0900a44780045a3a User Settings menu The User Settings menu The User Settings menu consists of one screen. Adjust the backlight level of the screen by moving the bar horizontally. This change will take effect immediately. 9896 002 16623 Figure 3.7 Admin Settings menu The Admin Settings menu consists of four screens.

5 5.1 Using the PDM Introduction Figure 5.1 Philips Healthcare The PDM The PDM is an active dose meter designed for maintenance-free usage throughout its lifetime. You can personalize the PDM’s appearance by attaching one of the 8 inlays of different color, which are delivered together with the PDM (see the PDM Quick Guide).
Getting started The PDM now records dose values and transmits them to Base Stations within range. You can also read out the recorded dose values by using DoseView via the Cradle (see section “Getting started with DoseView” on page 4-2). 9896 002 16623 0900a44780045a3a See the “Technical Data” chapter to learn more about PDM memory and data transfer between PDM and Base Stations. Philips Healthcare 4 5 6 5.
6 6.1 Using the Cradle Introduction Figure 6.1 The Cradle The Cradle is a dock station that lets you connect a PDM to a computer for data read out as well as PDM Options writing into the PDM. Use the Cradle in combination with the DoseView and/or Dose Manager applications.
Getting started 6.2 Getting started NOTE Do not connect the Cradle to the computer unless DoseView and the Cradle driver are installed on the computer. 1 Start the DoseView application. 2 Connect a Cradle to your computer’s USB port. 3 Put a PDM in the Cradle. 9896 002 16623 DoseView will start loading the PDM dose history. This may take up to a few minutes. You can follow the progress on the progress bar at the bottom of the DoseView window.
7 7.1 Philips Healthcare Maintenance Calibrating the Base Station screen If the touch screen does not respond correctly to user interaction, a touch screen re-calibration may be needed. 1 2 7.2 Follow the instructions below to perform a re-calibration: Tap and hold on the Philips start up screen that appears during Base Station startup until the Setup view appears. Follow the instruction on the bottom of the screen and the subsequent instructions in the next views.
Cleaning and disinfection Chrome parts should only be cleaned by rubbing down with a dry woolen cloth. Do not use abrasive polishes. To preserve the finish, use non-abrasive wax. Disinfection 7.2.2 CAUTION Do not use flammable or potentially explosive disinfecting sprays. Such sprays create vapors, which can ignite, causing fatal or other serious personal injury.
8 8.1 Troubleshooting Base Station Table 8.1 8.2 Base Station troubleshooting Problem Solution The PDM does not appear in the Online View. Use DoseView or Dose Manager to check that the PDM’s: • Battery Status is OK (see section “Change PDM options” on page 4-7). • Power Mode is set to ‘On’ (see section “Change PDM options” on page 4-7). • Base Station Mode is set to ‘Show’ (see section “Change PDM options” on page 4-7).

PDM memory 10.2 PDM memory The PDM has two dose data memories: • The accumulated dose memory, where the PDM stores accumulated dose values every hour for the entire lifetime of the PDM. • The dose rate memory, where the PDM stores dose rate samples. When the radiation exceeds 40 µSv/h, the PDM stores one sample per second. This memory is limited to 3600 second-samples. Base Station memory The Base Station stores dose information and PDM Info for PDMs that have been connected to it.
PDM and Base Station/DoseView memories 10.5 10.5 PDM and Base Station/DoseView memories Dose rate samples that have been overwritten in the PDM’s dose rate memory may still be available in the Base Station. If there are no dose rate samples neither in the Base Station, nor in the PDM dose rate memory, the Base Station and DoseView will instead display mean dose rate values based on accumulated dose values (see figure below).

Daylight saving time adjustment is done in the Base Station, 14 DoseView or Dose Manager when the dose history is presented. 15 16 The following happens when the daylight saving time is changed: 17 • When going to summertime, one extra hour with no dose data will be 18 19 added to the dose log.
