ALARM SUSPEND button. The M Series unit will
perform in the same way that we describe above for the
first alarm.
Silencing Alarm Tones
To silence the alarm tone, press and hold down the
ALARM SUSPEND button for between 1 and 3 seconds
(hold down button for at least one second, but
less than 3 seconds). The alarm tone stops, the
M Series unit displays the alarm’s bell icon in
inverse video with an “X” across it, and the value
of the alarm parameter remains highlighted. (If you press
the ALARM SUSPEND button again, alarm processing
is reactivated.)
The alarm tone will not sound again as long as the
physiological parameter’s value remains out of range.
If the alarm condition “clears” (the physiological
parameter returns to a value within range) after
you silence the alarm tone, the M Series unit
resets the alarm and displays the bell icon (no inverse
video, no “X”). The alarm parameter value displays
normally (no highlighting).
After the M Series unit resets an alarm, should the
physiological parameter again go out of range, it will
trigger the alarm.
Deactivating and Activating Alarms
To deactivate all alarms on the M Series unit,
press and hold down the ALARM SUSPEND
button for 3 seconds or longer. The bell icons for all
alarms will have an “X” through them to indicate that the
alarms are deactivated. Alarm parameter values display
normally (no highlighting).
To reactivate the alarms, press and release the ALARM
SUSPEND button in less than 1 second.
Smart Alarms
In Defib, Monitor or ON mode, ECG/heart rate alarm
capabilities are enhanced with the defibrillation advisory
feature called Smart Alarms
. When alarms are
operating, this feature triggers an audible alarm
whenever ventricular fibrillation or wide complex
ventricular tachycardias are detected. For advisory-
triggered alarms, an additional “CHECK PATIENT”
message will appear on the display and the chart
recorder print out.
If alarms are operating in Pace mode (Pacing version
only), the unit displays “VF ALARMS OFF”, indicating
that the Smart Alarms
 feature has been disabled.
If heart rate alarms are operating with paddles selected,
the unit will display the message “SELECT LIMB
LEADS”. If you see this message, select limb or
precordial leads. Better signal quality will be obtained
using limb or precordial leads rather than paddles. To
combine monitoring and defibrillation with heart rate
alarms enabled, use MFE Pads.
Recorder Operation
The strip recorder will document the ECG trace with a 6
second delay at all times. To start the strip recorder,
press the RECORDER button. The strip recorder will run
continuously until the button is pressed again.
Each time the strip recorder is started, the time, date,
ECG lead, size, and heart rate are printed on the top part
of the paper. If the unit is pacing, the output current will
also be printed. Similarly, if the defibrillator has been
discharged, the delivered energy will be printed.
Note: The paper supply should be checked at the
beginning of each shift and the end of each use
to ensure adequate recording capability. A
colored stripe on the paper means that the paper
supply is low.
A “CHECK RECORDER” message appears on the
display when the strip recorder is activated without
paper. The strip recorder automatically shuts off when
there is no paper.
Press the RECORDER button to start the strip recorder
again after loading new paper.
If your M Series unit does not function as expected, see
the Recorder Troubleshooting section on page B-3.
Diagnostic Bandwidth
When using an ECG cable for monitoring, the unit can be
switched to diagnostic bandwidth (0.05-150 Hz) by
pressing and holding the RECORDER button depressed.
Diagnostic bandwidth will be maintained as long as the
RECORDER button is held down. The unit will revert to
standard monitoring bandwidth when the RECORDER
button is released.
5 Lead Monitoring
Disconnect the 3-Lead ECG patient cable, if attached.
Connect the 5 lead ECG patient cable to the M Series
product. Refer to the beginning of this section for
appropriate Preparations (i.e., placement of electrodes,
attaching electrodes, setting the controls, etc.) to be
considered before performing 5 lead monitoring.
If any ECG lead becomes disconnected during
monitoring an “ECG LEADS OFF” message will appear
on the display.
The Smart Alarms feature is always disabled during
monitoring when augmented leads (AVR, AVF, AVL) or
V-leads are selected. The messages “VF ALARMS OFF”
and “SELECT LIMB LEADS” will be alternately displayed
when alarms are activated (the bell shaped character
will appear on the upper portion of the display) and
augmented leads or V-leads are selected. These
