Safety Considerations

The following section describes general warnings and safety considerations for operators and patients. Service
technicians should review the 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.

i

M Series Service Manual

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 upon 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.

Only qualified personnel should disassemble the M Series unit.

WARNING! This unit can generate up to 4500 volts with sufficient current to cause lethal shocks.

All persons near the equipment must be warned to “STAND CLEAR” prior to discharging the defibrillator.

Do not discharge the unit’s internal energy more than three times in one minute or damage to the unit may result.

Do not discharge a battery pack except in a Base PowerCharger
unit.

Do not use the M Series 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.

4x4

or compatible ZOLL Battery Charging/Testing

Do not use the unit near or within puddles of water.

NOTE The M Series 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 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.

Maintenance Tests

Overview

The M Series has two checkout procedures: the operator’s shift checklist and the extensive six-month maintenance
tests checkout procedures.

Because the M Series units must be maintained ready for immediate use, it is important for users to conduct the
Operator’s Shift Checklist procedure at the beginning of every shift. This procedure can be completed in a few minutes
and requires no additional test equipment. (See the ZOLL M Series Operator’s Guide for the Operator’s Shift
Checklist.)

A more thorough maintenance tests checkout needs to be performed by a qualified biomedical technician every six
months to evaluate that the functions of the M Series unit work properly. This chapter describes the step by step
procedures for doing the six month maintenance tests checkout. (See the Appendix of this manual for the ZOLL M
Series Maintenance Tests Checklist which you should photocopy.)

Note: The following tests are to be performed only on M Series units equipped with the optional pacing function.

The pacer output can be measured using an oscilloscope set to DC coupling connected across a load resistor. (See

+

diagram in column for universal cable connector polarity.) The load resistor is a 100 ohm, 5 watt or greater. The pacer
output is a positive going pulse, 40 +/- 2 ms duration with an amplitude of 0.1 volt per milliamp of selected output
(e.g., 40 milliamps of selected output has an amplitude of 4 +/- 0.5 volts the specified tolerance displayed on the
oscilloscope).

If an external non-invasive pacer analyzer is being used, then follow the manufacturer’s guidelines for measuring the
frequency (ppm), output (mA) and the pulse width measured in milliseconds. Note that the analyzer pace load resistor
must be less than 250 ohms.

Troubleshooting

The following tables show the most common troubleshooting issues and their solutions.

First, attempt to solve the problem with “Recommended User Action.” If these steps do not solve the problem, follow
the steps listed in the “Recommended Technical Action” column.

Reported Problem Recommended User Action Recommended Technical Action

ECG LEAD OFF message displays.
(3, 5, 12 lead cable)

• Check preparation of ECG electrode site by

cleaning the site, lightly abrading the
patient’s skin and/or clipping the patient’s
hair at the electrode site.

• If electrode gels are dry, replace electrodes

with new ones from a freshly opened
package.

• Verify that all leads are attached.

• Set monitor to another lead.

• Verify that the electrodes have not exceeded

their expiration date.

• Try to reproduce the problem using a simulator.

• Inspect the ECG cables looking for corrosion

or broken connector pins.

• Check the cable for intermittent connections by

flexing the cable at the yoke and snap
connectors.

• Check the cable connection to the defibrillator.

• Inspect the ECG input connector and its pins.

Replace it, if necessary.

• Inspect the ECG cable connection to the system

board.

• Inspect the system board ECG shielding.

• Remove and replace the system board.

• If a V1 lead wire metal snap comes in

contact with the patient’s skin, then the
system will show all V leads as OFF.

• Remove V1 leads and others away from the

patient. Turn off the unit and wait ten
seconds before turning it back on.

• Remove and reinsert PADS connector into the

universal cable.

• Check for damaged defibrillator pads, wires and

or connector.

• Check for dried out or expired defibrillator

pads.

• Clip (not shave) the patient’s hair and wipe

pad contact area dry.

• Connect the cable to the test plug. The

DEFIB PAD SHORT message displays to
indicate that the cable is functioning
properly.

• If the DEFIB PAD SHORT message

displays, then check the connections of the
pads to the patient and to the defibrillator
cable.

• If the DEFIB PAD SHORT message does

not display, remove the defibrillator from
service.

• Connect universal cable to the shorting plug.

The DEFIB PAD SHORT message should
display, when you SELECT PADS. If the
message does not display, then:

• Try another universal cable.

• Check the cable from the universal cable

connector to the High Voltage Module.

• Check the cable from the High Voltage Module

to the system board.

• Remove and replace the High Voltage Module.

• Remove and replace the system board.

• Call ZOLL Technical Support for assistance.

M Series Service Manual

Reported Problem Recommended User Action Recommended Technical Action

Flash or arcing under defibrillator
pad.

• Avoiding using alcohol and betadine in and

around the treatment area because these
skin preparations may lead to increased
conductivity and/or bonding between the
electrode’s adhesive and skin.

• Check for gel droop. If the gel has leaked

out of the gel treatment area, replace the
electrode.

• Ensure pads are coupling to the patient’s

skin and connected to the universal cable.

• Check for dried out gel on the defibrillator

pad.

• Clip patient’s excessive hair. Do not shave

hair.

• Check expiration date. Replace pad if date

has expired.

• Do not conduct chest compression through

the pads because the pads could be damaged
leading to the possibility of arcing and skin
burns.

• Wet gel pads must be stored flat.

• Apply the back electrode first. If the front

electrode is already in place when the
patient is being maneuvered for placement
on the back, the front may become partially
lifted, possibly causing arching and skin
burns.

Zoll M Series Error Messages

The following is a list of Zoll M Series error messages that may appear on your display. The “User Advisory” column
informs you about an action in progress or provides feedback on a user correctable situation that typically does not
require further technical support. The “Technical Action” column describes what you as a technician can do to correct
the situation. Note that these messages will sometimes overlap part of the waveform display.

First, attempt to clear the message by turning the Selector Switch to OFF for ten seconds, then back to the desired
operating mode. If the fault persists, call ZOLL Technical Service.
