3. DIAGNOSTIC CHECK Introduction The instrument has two check programs which automatically or manually diagnose the instrument. The automatic check program (power on self check) is executed whenever the instrument is turned on. The manual check program can be executed at any time. All errors detected during the power on self check, manual check, and any time in monitor mode are stored in an error history table that you can view.
3. DIAGNOSTIC CHECK Power On Self Check The following icon appears during the power on self check. If no error is detected, the monitor mode begins and the patient monitoring display appears. If a serious error which does not allow the host CPU to execute the system program any more is detected, the screen changes to the following DIAGNOSTIC CHECK screen and the error mesage is displayed.
3. DIAGNOSTIC CHECK The MAIN board and DPU board are checked as follows: • CPU ROM CHECK: Checks the system ROM for the host CPU on the MAIN board. The MAIN board will be faulty if an error which causes a partial screen problem is found. • CPU RAM CHECK: Checks the system RAM for the host CPU and patient data storage. The MAIN board will be faulty if an error which causes a screen problem is found. • DPU ROM CHECK: Checks the system ROM for the CPU on the DPU board.

To exit the DIAGNOSTIC CHECK screen and return to the patient monitoring mode, touch the “MONITOR MODE” key. Service Manual BSM-4100 3.
3. DIAGNOSTIC CHECK CPU Check Menu Items The CPU check menu items check the function of the CPU peripherals such as ROMs, RAMs, Switches, Touch Key, Sound generators, Alarm indicators and external memory modules. ROM Check This item checks the ROMs on the MAIN board by the CRC (cyclic redundancy check) technique. This check assigns a count number when one set of checks is successfully completed. A set of checks takes about 1 minute and 30 seconds.
3. DIAGNOSTIC CHECK RAM Check This item checks the RAM on the MAIN board by comparing the test patterns it first wrote to the RAM with the test patterns it later read from the RAM. This test uses 15 test patterns and assigns a count number when a comparison of the 15 test patterns is successfully completed. The comparison of all the test patterns in this check takes about 4 minutes. This check deletes the patient data. If an error message appears, the MAIN board will be faulty.
3. DIAGNOSTIC CHECK Hard Key Check This item checks the operation of the hard keys on the front panel and the function dials. The hard key and dial layout appear. Pressing the hard key or rotating the function dial usually highlights the corresponding hard key or dial on the screen. If the pressed hard key is not highlighted, the hard key may be faulty. If more than one hard key has this symptom, the operation board, function dial board or MAIN board will be faulty.
3. DIAGNOSTIC CHECK Touch Key Check This item checks the touch key operation and positioning. When you start the check, the screen changes to the touch key check screen, and indicates the position where you touched. When you touch the screen and move your finger or touch pen, the target mark traces your position. If the position of the target mark and the touched position do not match, calibrate the touch screen.
3. DIAGNOSTIC CHECK Sound Check This item checks the 7 types of sounds generated by the instrument. This check can also be used to check the alarm circuit and the QRS beep circuit. Check the quality of sound, loudness, noise, incorrect sound, etc. If there is no sound or distorted sound, the speaker or MAIN board will be faulty. Procedure to Check the Sound 1. To check the sound, touch the “SOUND CHECK” key. 2.
3. DIAGNOSTIC CHECK COM RAM Check This item checks the dual port RAM for communication between the host CPU on the MAIN board and CPU on the DPU board. The check method is the same as the system RAM check. The check program indicates the address, write data and read data if an error is detected. This RAM is located on the DPU board. Therefore if an error is detected, the DPU board or connector which connects the MAIN and DPU boards will be faulty.
3. DIAGNOSTIC CHECK ALARM INDICATOR Check This item checks the function of the alarm indicator located on the top of the instrument. Check the light of indicator lamp according to the screen indication. If the color does not light, the connection cable is loose or disconnected or the MAIN board or indicator board will be faulty. If the indicator lights partially, the indicator board is faulty. Procedure to Start the ALARM INDICATOR Check Program 1.
3. DIAGNOSTIC CHECK OTHER Check This item checks the clock IC and backup NVRAM (EEPROM). The NVRAM contains the system setup data. The check program checks correspondence between write and read data with the stored data retention. Therefore, this check does not damage the system setup data. If the clock IC and NVRAM have no error, the “OK” message appears on the screen and current date and time appear at the top of the screen. If an error message appears, the MAIN board will be faulty.
3. DIAGNOSTIC CHECK MEMORY CARD Check This item checks the inserted PCMCIA card and its interface. There are two checks. The ATTRIBUTE CHECK displays the dump list of attribute area which is in the PCMCIA card. The COMMON CHECK is the write/read check for common area. This check continues until you touch the “STOP” key or “RETURN” key. The check method is the same as the system RAM check. If the PCMCIA card is not inserted, the program displays the CARD NOT INSERTED message on the screen.
3. DIAGNOSTIC CHECK ATA CARD Check This item checks the ATA card (QM-421P) and its interface. This check is almost the same as the MEMORY CARD check, except for the COMMON CHECK. The COMMON CHECK is the write/read check for common area by each sector. This check continues until you touch the “STOP” key or “RETURN” key. The check method is the same as the system RAM check. If an error is detected, the QM-421P or MAIN board will be faulty. Procedure to Start and Exit the ATA CARD Check Program 1.
3. DIAGNOSTIC CHECK Backlight Check This item checks the brightness control of the LCD backlight. While the brightness is manually changed, check that it changes smoothly with no twinkling. Check that the backlight goes off and has no twinkling when the brightness is set to minimum. If the brightness does not change smoothly or the light goes off in the middle of the brightness bar on the screen, it indicates the end of life of the backlight or faulty inverter board.
3. DIAGNOSTIC CHECK CRTC Check Menu Items The CRTC check menu items check the function of the display control block, including the LCD unit. These check results cannot be recognized by the host CPU, so you must judge the result. If an error is found, the MAIN board will be faulty. GRAPHIC MEMORY Check and CHARACTER MEMORY Check These items check the Graphic RAM and Character RAM on the MAIN board for the waveform display or character display by the write/read check technique.
3. DIAGNOSTIC CHECK GRAPHIC DRAW Check This item checks the function of the graphic draw plane. Check the figure of display and colors. At the same time, it checks for defects of LCD pixels all over the screen. The plane for wave/graphic screen is in 20 screens and the check program displays 4 planes at a time. If the screen has a wrong display, the MAIN board or LCD unit will be faulty. Procedure to Execute the GRAPHIC DRAW Check Program 1. To select the Check, touch the “GRAPHIC DRAW CHECK” key.
3. DIAGNOSTIC CHECK Screen Flow of GRAPHIC DRAW Check Program Touch Key Record Touch Key MENU For the TFT LCD screen, it is considered normal if some pixels have randomly abnormal color or do not light. (Up to 25 wrong pixels are considered normal at the maximum brightness.) Service Manual BSM-4100 3.
3. DIAGNOSTIC CHECK CHARACTER DRAW Check This item checks the function of the character draw plane. Check the character display and colors. The plane for character screen is prepared in 4 screens and the check program displays one plane at a time. Procedure to Execute the CHARACTER DRAW Check Program 1.
