User Manual for Pulse Oximetry with PocketViewer

Please hold your PocketViewer in your hands.

The PocketViewer turns on after touching the screen. That's why there is a cover for it. Once you take the cover off to use the device, please fix it on the backside. Take care of it and don't forget it anywhere!

The same applies for the stylus. The stylus is for writing on the sensitive screen. Don't use any other pointer. They can damage the screen. Once you don't need the stylus any more, put it back to it's place, so that you don't loose it. Below the screen there is a button "Off".  Touch this button to turn off your PocketViewer.

The PocketViewer works with two AAA size cells or batteries. The endurance of the batteries is about 100 hours, depending on intensity of use. To replace the batteries, turn off the device and slide the battery switch to the "REPLACE BATTERIES" position, remove the battery compartment cover and replace the batteries. After closing  the battery compartment cover, the switch should be put back to normal (right) position labeled "NORMAL OPERATION".

At the back of the device you will find the reset button behind a 2 mm hole.  One can press it with the stylus. If you want to reset, the device must be on. After reset you have to calibrate the touch screen with four touches at the marked places. You can answer the question about contrast with OK. Than you have to decide whether you want a hard reset. This will delete all data, even the pulse oximetry application program. If you answer NO, you will have a soft reset. Once the clock appears, you can adjust the time and date by tapping the clock. This type of adjustement is normally completed with "Next" or "Set" button controls.

If a soft reset has no success, you can try a hard reset. This makes sense only if you are able to install all the application programs again. See description under.

Tap the "Menu" button to choose an application program for execution. It will show you a menu screen with icons of all available programs. The PocketViewer is equipped by Casio with many different programs. That's why  the menu has two pages, that you can choose using the double arrow buttons on the right side of the screen. The page number shows up as 1/2 or 2/2 on the right side of each page. The application program for pulse oximetry is named SPO2 and appears on the second page. Tap on the symbol to start the application program.

Close the  pulse oximetry program. Tap the button "Menu" and afterwards tap "Off" - the device turns off.

The PocketViewer comes with a serial connection cable, with it you can:

• connect the PocketViewer to a PC.
• connect the pulse oximeter to the Pocketviewer.

The small plug on the cable with the inscription "Push" will be plugged into the enclosure right on the bottom of the PocketViewer. Be careful: The plug mechanically locks in position and can be taken off only after releasing the lock by pressing the plug between thumb and forefinger. Then the lock comes free without force.

For the installation and update of the application program SPO2 download the file SPO2.bin. Besides that you need the PocketViewer Application Manager PVM.exe for execution on your PC. This software by Casio supports management of applications, application data files and system updates for the PocketViewer.

Save both files in a disk folder on your PC.

Connect the PocketViewer to a serial interface of your PC. Switch on your PocketViewer and start the update with the button "Menu Bar" in the right corner below the touch screen. Start the function "Option -> Download" in the dropdown menu that appears at the top of the screen. Then the PocketViewer waits for commands from the PC.

Afterwards start the application programm PVM.exe, that you downloaded before. Choose under Comm Setup the serial interface, that you used to connect the PocketViewer, and under "Speed" the baud rate, e.g. 9600. With higher baud rates there may be data transfer problems. Then you import the current PocketViewer setup using the "Execute -> Import From PV" menu command. After a short data transfer time you will see a list of application programs, that are saved in your PocketViewer. Mark SPO2 with the mouse and tap onto the "-" button in the toolbar. After confirmation of the question SPO2  desappears from the list. It means you prepared removing the old version..

Tap the "+" button in the toolbar and choose the new SPO2.bin, that you already downloaded from http://www.cadt.de . Now you can add some text as comment, that will acompany the application on your PV. You can leave this blank. After comfirmation you start the PocketViewer software update using the "Execute -> Update PV" menu command. The data transfer takes about one minute.

Later the screen of the PocketViewer shows again the page with the application menu (application icons). Go to the second page and start SPO2!

In case of problems:

• The PocketViewer must be on.
• If communication takes to long, the PocketViewer stops waiting. You can tap Menu Bar -> Options -> Download again.
• The serial cable must be separeted from the pulse oximeter and connected to the PC. Check if you are connected with the correct serial interface, e.g. "COM1" or "COM2".
