6DIHW&RQVLGHUDWLRQV Service technicians should review these safety considerations prior to servicing any equipment and read the manual carefully before attempting to disassemble the unit. Only qualified personnel should service the M Series unit. Federal (U.S.A.) law restricts this unit for use by or on the order of a physician. 1RQ=2//PDQXIDFWXUHGDFFHVVRULHV Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug Administration (FDA) under section 510(K) of the Medical Device Act to obtain approval to market is based on the use of ZOLL accessories such as disposable electrodes, patient cables and batteries. The use of external pacing/defibrillation electrodes and adapter units from sources other than ZOLL is not recommended. ZOLL makes no representations or warranties regarding the performance or effectiveness of its products when used in conjunction with pacing/defibrillation electrodes and adapter units from other sources. If unit failure is attributable to pacing/defibrillation electrodes or adapter units not manufactured by ZOLL, this may void ZOLL's warranty. :DUQLQJV All persons near the equipment must be warned to “STAND CLEAR” prior to discharging the defibrillator.
:DUQLQJ
SHOCK HAZARD! The M Series CCT unit can generate up to 2400 volts with sufficient current to cause lethal shocks.
Do not discharge the unit’s energy internally more than three times in one minute or damage to the unit may result. Do not discharge a battery pack except in a Base PowerCharger4x4, a compatible ZOLL Battery Charging/Testing unit, or an M Series unit. Do not use the M Series unit in the presence of flammable agents (such as gasoline), oxygen-rich atmospheres, or flammable anesthetics. Using the unit near the site of a gasoline spill may cause an explosion. Do not use the M Series unit near or within puddles of water. 5DGLR)UHTXHQF,QWHUIHUHQFH 5), The M Series unit is protected against interference from radio frequency emissions typical of two-way radios and cellular phones (digital and analog) used in emergency service/public safety activities. Users of the M Series unit should assess the unit’s performance in their typical environment of use for the possibility of radio frequency interference from high-power sources. Radio Frequency Interference (RFI) may be observed as shifts in monitor baseline, trace compression, or transient spikes on the display.

3ULQFLSOHVRI2SHUDWLRQ The Temperature option on the M Series CCT unit provides temperature monitoring for adult and pediatric patients. The M Series unit can monitor temperature on two different channels and display the two values (T1 and T2) on the monitor, as well as ∆T, the absolute value of the difference between them.
7HPSHUDWXUHFRQQHFWRU The IBP/Temperature module resides in the lower housing assembly of the M Series CCT unit. A YSI 400 compatible temperature probe connects to the M Series CCT unit through the temperature connector on the front of the unit. You can use a two-channel Y-adapter to simultaneously connect two temperature probes to the M Series CCT unit. Figure 1-1: M Series CCT unit with temperature monitoring option

This checkout procedure can be completed in a few minutes and requires no additional test equipment. See the M Series Operator’s Guide for the Operator’s Shift Checklist. In addition, a qualified biomedical technician should perform the following maintenance procedure every six (6) months to ensure that the M Series Temperature option is operating properly: • “Temperature Monitor Test” on page 4
5HFRUGLQJRXUUHVXOWV Photocopy the checklist at the back of the M Series Service Manual and use the copy to record the results of the maintenance tests. As you complete each step in a procedure, mark the appropriate Pass/Fail/NA box, and keep the checklist for your maintenance file.
