II. Installation & Operation Procedure
1. S/W Installation
Before installing of the RealWave program on PDA, you must install ActiveSync on your PC.
Please refer to the chapter VIII to install ActiveSync. After installation of ActiveSync, connect PC
with PDA via USB cable and Insert the CD. Run the RealWave.exe file from the RealWave folder of
the CD-Rom drive. When the window appears like [Fig. II-1-1] and click ‘Next’, it can be proceed to
[Fig. II-1-2] and [Fig. II-1-3]. And then click ‘OK’to finish installation [Fig. II-1-3].
Realwave.ARM.CAB files use when installing a program from PDA directly.

[Fig. II-1-3] Installation window 3
[Fig. II-1-4] Run of RealWave program 1
[Fig. II-1-5] Execute RealWave program 2

To run Launch RealWave program, click the tap [Start >> Programs], and then click ‘RealWave”
icon on the window of [Fig. II-1-5].
2. Run and Registration
2. 1 Unregistered PDA
If running RealWave program at unregistered PDA, please enter given license number on the
register window when appears a window like [Fig. II-2-1,2]. The license number is limited at only
one PDA. Once registered, RealWave program doesn’t work properly if the license number is
different. Please contact us when you have a problem with the license number.
[Fig. II-2-1] Registration window [Fig. II-2-2] Entering license number
2. 2 Pre-registered PDA
If you have PDA included package, program will start without register procedure like [Fig. II-2-1].
In case of no H/W or failure to recognize, icons in the red box are not activated like [Fig. II-2-3]. But
in case of the opposite, icons are activated and ready to measure like [Fig. II-2-4].

3. Firmware Upgrade
3. 1 Check firmware version
If you select [About RealWave] menu in [File], dialog window appears in [Fig. II-3-2]. You can
check the information of hardware including firmware version.
[Fig. II-3-1] Select [About RealWave…]
menu
[Fig. II-3-2] Check firmware version
3. 2 Firmware Upgrade
Smart Sound/Vibration Analyzer H/W has firmware inside, so the firmware has to be upgraded
when the new version is released. First, ‘FirmUp1.0_ENG.exe’ file in the RealWave software CD has
to be copied at a proper folder in PDA. Here is the way to copy it:
1) Copy the ‘FirmUp1.0_ENG.exe’ in the RealWave software CD.
2) Connect PDA with PC using a USB cable.
3) After ActiveSync connected, double click the ‘Mobile Devices’folder on the windows explorer.
Several folder in PDA will be found.
4) Paste ‘FirmUp1.0_ENG.exe’ to the proper PDA folder.
[Fig. II-3-3] ~[Fig. II-3-4] shows a copy of ‘FirmUp1.0_ENG.exe’ file.
[Fig. II-3-3] Copy and Paste in the Window Explore
[Fig. II-3-4] Run ‘FirmUp.exe’
file on PDA

9
When running ‘FirmUp1.0_ENG.exe’ file on PDA, the program runs like [Fig. II-3-5]. Press
[Open] button on the window of [Fig. II-3-6]. Select folder and file (*.bin) to update and press [Open]
button on the window of [Fig. II-3-7].
[Fig. II-3-5] FirmUp window [Fig. II-3-6] Open a file to update
[Fig. II-3-7] Completion to open a file to update
At [Fig. II-3-7], press [Start] button to start update. You must insert front-end H/W before update. It
is highly recommended to use AC adaptor or USB cable, but not to use PDA while updating. It is very
harmful that H/W is removed from CF card slot or shut down compulsorily while updating. If it
causes, you can’t to update it and the hardware has to be repaired.
You must turn off PDA after finishing upgrade(Or remove hardware from PDA and then insert
hardware again).
Attention before updating firmware!
1. Use of AC adaptor or USB cable is highly recommended.
It is very harmful to use PDA while updating.
If the firmware upgrade is failed, the hardware can’t be used anymore and must
be repaired.
Attention after updating firmware!
1. Turn off the power of PDA, and then Turn on.
