Users should have a thorough knowledge of the operation before using this system. Pay attention to the following when installing and storing the equipment. Do not install or store in an area where the equipment will be subject to splashing water.
Page 12: Precautions For Safe Operation Of Medical Telemetry
When interference or breakdown occurs in telemetry communication, the user is required to inform the zone manager and the overall manager of the problems. The zone manager and overall manager are to deal with the problem properly and/or contact their nearest Fukuda Denshi representative for service. viii...
Page 13: Precautions About The Maintenance
Maintenance, Modifications, and Repairs Fukuda Denshi is liable for the safety, reliability, and performance of its equipment only if; Maintenance, modifications, and repairs are carried out by authorized personnel. Components are used in accordance with Fukuda Denshi operating instructions.
Page 14: Precautions About Pacemaker
W A R N I N G For more details, contact FUKUDA DENSHI personnel, your institution’s professionals, or your pacemaker distributors. Reference “Minute Ventilation Rate-Adaptive Pacemakers”...
Page 15: Electrosurgery Safety
Electrosurgery Safety The monitoring system contains protection against interference generated by electrosurgical instruments. However, operating conditions, surgery site with respect to the location of ECG electrodes, or the type of instrument used, may cause noise on the ECG. The noise is generated at the tip of the electrical knife and is difficult to completely eliminate because of the frequency components of the ECG.
Page 16: Peripheral Devices
For safety and good performance of this equipment, connection of other manufacturers’ equipment to the monitor is not authorized, unless the connection is explicitly approved by Fukuda Denshi. It is the user’s responsibility to contact Fukuda Denshi to determine the compatibility and warranty status of any connection made to another manufacturer’s equipment.
Page 17: Precautions About The Ds-8500 System
D A N G E R Danger such as electric shock may result to the patient and operator. Do not connect a unit or cable not authorized by Fukuda Denshi to any I/O connector. If done so by mistake, the DS-8500 system cannot deliver its maximum performance and the connected units may be damaged, resulting in a safety hazard.
Page 18 (x4). Otherwise, the equipment may fall from the trolley, resulting in injury to the operator or damage to the equipment. Use the trolley only with the equipment specified by Fukuda Denshi. Otherwise, the monitor and trolley may fall down, resulting in injury or damage to the monitor.
Page 19 Systems Use only the accessories specified for this device. Otherwise, proper function cannot be executed. Do not use the touch panel with the film attached. Malfunction of the touch panel or damage may result. Due to its material characteristic, the touch panel expands/contracts depending on the temperature/humidity.
Page 20 When continuously detecting AC noise artifact as pacemaker pulses, QRS detection stops and heart rate is extremely degraded. Also arrhythmia cannot be detected. Respiration Monitoring When a defibrillator is used during respiration monitoring, a large offset voltage will be placed on the ECG electrodes, which may cause interruption of monitoring for a few seconds.
Page 21 Each time the blood pressure transducer or tubing is replaced, the zero balance procedure is required to ensure accurate measurements. “Perform zero balance” message will not be displayed unless the three-way valves of all pressure transducers are opened to air. If the status is not displayed, or if “Open stop cock to air”...

Page 24: Precautions About The Wired Network System
Precautions about the Wired Network System (DS-LAN ΙΙ/DS-LAN ΙΙΙ) W A R N I N G Do not connect unspecified device to a wired network. If performing wired network transmission, configure the display so that the numeric data corresponded to the waveform is displayed. If not, the displayed waveform or numeric data may not be transmitted.
Page 25: Precautions About The Wireless Network System
Precautions about the Wireless Network System When monitoring a patient using wireless telemetry, make sure the patient D A N G E R data is properly received at the central monitor. Pay special attention when the channel ID at the bedside monitor is changed. A password can be set to access the channel ID setup menu to allow only the telemetry channel administrator to change the channel ID.

DS-8500 Main Unit This section explains the block diagram of the DS-8500 and its function. Main CPU Board (PCB-7303) Circuit Explanation The Main CPU Board controls, displays, and records the monitor. The input signal operation of the touch panel, remote control, etc are processed by the CPU and then the display of the monitor or each measurement condition will change.
Page 59 RTC (Real Time Clock) RTC (Real Time Clock) is IC exclusively for timing. As with SRAM, RTC operates with the power supply from the long-term backup battery (lithium battery) while the power is turned OFF (while the power is ON, RTC operates with the external power supply). The main CPU obtains the time/date from the RTC during start-up, and then the main CPU conducts the timing by itself.
