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.

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.
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.

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.

SHOCK HAZARD!
The M Series CCT unit can generate up to 2400 volts with
sufficient current to cause lethal shocks.

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.
7HPSHUDWXUHFRQQHFWRU
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
See the M Series Temperature insert of the M Series Operator’s Guide for information on operating
the Temperature option.
The M Series CCT unit can display temperature values in either degrees Celsius or degrees
Fahrenheit. See the M Series Configuration Guide for information on changing temperature
units of measurement.

The M Series Temperature function measures body temperature by processing electrical
signals from a thermistor-type temperature probe contacting the patient. When the
M Series CCT unit detects a connection to a temperature probe, the unit initiates
temperature measurement automatically.
The temperature measurement cycle proceeds as follows:

It is important that users conduct the Operator’s Shift Checklist procedure at the beginning
of every shift to maintain the M Series unit ready for immediate use. 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
5HFRUGLQJ\RXUUHVXOWV
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. Complete all the steps of the procedure before
evaluating the test results.

The temperature monitor test verifies the accuracy of measurements on both temperature
channels of the M Series CCT unit.
5HTXLUHGHTXLSPHQW
You need the following equipment to complete the temperature monitor test:
•M Series CCT unit with Temperature option (with fully-charged battery installed)
•Fogg TP400 Temperature Probe Simulator (or equivalent)
•2-channel Y adapter (ZOLL p/n 8000-0675) if using T2 channel
%HIRUH\RXEHJLQ
Before you begin the temperature monitor test:
•If testing temperature channel 2, connect the 2-channel Y adapter to the temperature
connector (T1/T2) on the M Series CCT unit.
•Connect the Temperature Probe Simulator cable(s) to the temperature connector (T1/T2)
on the M Series CCT unit or to the 2-channel Y adapter.
