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

The Critical Care Transport (CCT) option on the M Series provides expanded display
capabilities for ECG monitoring and extends M Series vital signs monitoring options to
include two invasive pressure channels and two temperature channels. In addition, the
M Series CCT unit provides color display of monitored parameters and includes a VGA
output port for connection to an external VGA display.

The M Series CCT unit can display three separate waveform traces simultaneously in
MONITOR mode. Trace 1 is reserved for ECG monitoring, and Traces 2 and 3 are userconfigurable. In PACER or DEFIB mode, advisory messages appear in the Trace 3 display
area under certain conditions.

The M Series CCT unit provides color display functionality for monitored parameters. You
can assign specific colors to different parameters displayed on the M Series CCT monitor
By default, parameter colors are assigned as follows:
See the M Series Configuration Guide for information on configuring color display settings.
The M Series CCT unit provides a VGA output connector so that you can display
parameters on an external monitor equipped with an industry-standard 15-pin
To conserve battery power, the VGA output port is not active at power-up. See the M Series
CCT insert to the M Series Operator’s Guide for information on connecting the M Series CCT
unit to an external display monitor.
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 with the target VGA monitor every six (6) months to ensure that the M Series
CCT function is operating properly:
• “VGA Output Test” on page 4
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 VGA Output test verifies that the VGA port on the front of the M Series CCT unit is
operating properly and that information from the M Series CCT unit is displayed correctly
on the connected monitor.
You need the following equipment to complete the VGA output test:
• M Series CCT unit (with fully-charged battery installed)
• display monitor with VGA connector
Follow these steps to perform the VGA output test.

This section describes the following procedure:
• “Removing the CCT Front Panel” on page 5
Only properly trained technicians should service the M Series CCT unit. Ensure that you
take the appropriate safety precautions before disassembling any part of the M Series CCT
Take necessary precautions to guard against shock or injury before
conducting defibrillator tests or repairs. The M Series CCT unit
can contain lethal voltages even when turned off.
• Wear a conductive wrist strap that touches your skin and is connected to a grounding
mat and to an earth ground when working with static-sensitive units. Remove the wrist
strap when you discharge high voltage or when you are working on energized
The M Series CCT unit has a specialized front panel that includes a VGA output connector
and a larger LCD screen.
This procedure is similar to the procedure for removing the front panel from a standard
M Series unit. Refer to the M Series Service Manual, “Removing the Front Panel” (Chapter 3:
Disassembly Procedures) for more information.
You need the following tools to remove the front panel from the M Series CCT unit:
• flat blade screwdriver
• #2 Phillips screwdriver
• orange wood stick
Remove all power sources, such as the battery and power cord.
Ensure that you are familiar with the procedure for removing the ZIF
Keeper; damage to the unit may result if not performed correctly. See the
M Series Service Manual (Chapter 3: Disassembly Procedures) for more
Follow these steps to remove the front panel from the M Series CCT unit.
