LINE ISOLATION MONITOR TRANSIENTS—Line
isolation monitor transients may resemble actual cardiac
waveforms, and thus cause incorrect heart rate
determinations and alarm activation (or inhibition).
MRI USE—Do not use the equipment during MRI
scanning; conducted current could potentially cause
burns.
PATIENT CABLES AND LEADWIRES—Do not use
patient cables and electrode leads that permit direct
connection to electrical sources. Use only “safety” cables
and leadwires. Use of non-safety patient cables and lead
wires creates risk of inappropriate electrical connection
which may cause patient shock or death.
PACEMAKER PATIENTS—Rate meters may continue to
count the pacemaker rate during occurrences of cardiac
arrest or some arrhythmias. Do not rely entirely upon
rate meter alarms. Keep pacemaker patients under close
surveillance. Refer to your monitor’s operator’s manual
for disclosure of the pacemaker pulse rejection capability.
SIMULTANEOUS DEVICES—Do not simultaneously
connect more than one device that uses electrodes to
detect ECG and/or respiration to the same patient. Use
of more than one device in this manner may cause
improper operation of one or more of the devices.
STRANGULATION—Make sure all patient cables,
leadwires, and tubing are positioned away from the
patient’s head to minimize the risk of accidental
strangulation.

TRIMLINE TOCOTRANSDUCERS—If the monitor is on
when you connect or re-connect a Trimline
Tocotransducer to the UA connector, you must wait at
least 10 seconds before pressing the UA Reference button.
If the monitor is off, you must wait at least 10 seconds
from the time the monitor is powered on.
2. Plug a tocotransducer into the transmitter’s UA connector. Verify the
following on the monitor:
If the monitor has a UA display: the display reads an arbitrary
pressure value.
If the monitor does not have a UA display: turn on the strip chart
recorder and check that TOCO prints on the paper’s mode
annotation line.
Figure 4-17. Connecting a Tocotransducer or IUPC Cable
,03257$17
DEFAULT REFERENCE VALUE—Most monitors have
a default UA reference of 10 relative units. Take into
consideration that newer model monitor’s can be
configured to store a custom default value.

2003720-001
Setup Procedures: Performing a Functional Checkout
3. Press the monitor’s UA Reference button to set the UA value to 10
relative units. Verify the following on the monitor:
If the monitor has a UA display: the display reads 10 relative
units.
If the monitor does not have a UA display: turn on the strip chart
recorder and check that the UA REF message and TOCO mode
annotation both print on the paper.
4. Apply gentle pressure to the tocotransducer pressure sensing button
and verify that the monitor (display or uterine activity trace)
responds to the pressure input. Increasing force should produce an
increasing value and vice versa.
If no pressure changes are recorded, ensure that the corresponding
interconnection cable is firmly attached to both the monitor and the
receiver.
5. This step applies to monitors which support IUP monitoring. Place
the receiver’s UA Mode Selector switch in the IUP position. Verify the
following on the monitor:
If the monitor has a mode indicator: the IUP mode should be
indicated.
If the monitor does not have a mode indicator: turn on the strip
chart recorder and check that the IUP mode annotation prints on
the paper.
127(Place the UA Mode Selector switch back in the TOCO position
unless you plan to monitor with an IUPC.
4-16 Model 340 Telemetry System Revision B
2003720-001
Setup Procedures: Performing a Functional Checkout
Testing the Remote Event Marker Function
1. Plug the Remote Event Marker into the transmitter’s Remote Marks
connector.
2. Turn on the monitor’s strip chart recorder.
3. Press the Remote Event Marker’s pushbutton for at least one second.
Verify that an appropriate mark is printed on the paper:
: This annotation is commonly used to record an “event.” This
mark is available on all Corometrics-brand monitors.
: This annotation is commonly used as an indication that the
mother has perceived fetal movement. (Refer to your monitor’s
operator’s manual to learn if your monitor supports this feature.
Refer to your monitor’s service manual for information about
enabling the option.)
Testing the Environment
Decide on which areas of your facility will be used for ambulatory
monitoring. Test each location separately to rule out rooms that are
restricted due to metal structures blocking signal transmission.

DESIGNATED AREAS—Show the patient the areas that
are within signal range and where signal reception is
clear.
1. Instruct the patient to wear the Model 340T Transmitter with the
antenna pointed towards the Model 340R Receiver when possible.
2. Adjust the carrying strap to a comfortable length.
3. Encourage the patient to walk in a smooth, gliding motion. It is
preferable to slide feet rather than moving quickly which may cause
bouncing and artifact.
4. Instruct the patient, following each fetal movement, to listen via the
headset, for continued fetal heart rate tones.
127(Transducers with short
cables are available. Contact your
Information Technologies Sales
Representative.
5. Make sure the transducer cables are not dragging on the floor. If the
patient is in danger of tripping over the cables, drape them over the
patient’s arm; or shorten the length by taping a loop.

Monitoring via Telemetry: Monitoring Reminders
Monitoring Reminders
General
Use the correct interconnection method according to your monitor
model. See page 4-2 and page 4-5.
Remember to apply power to all three devices: monitor, receiver, and
transmitter.
Check that each interconnection cable is firmly attached to both the
receiver and the monitor.
As soon as any telemetry mode is detected, the front panel of the 120
or 170 Series Monitor is disabled and all front panel inputs are
ignored. In other words, telemetry and monitor modes cannot be
“mixed and matched”; you must use telemetry only or direct
monitoring only.
,03257$17
170 SERIES—For proper operation with a 170 Series
Monitor, disconnect all transducers from the front panel
of the monitor.
Ultrasound
Use only Corometrics 5700 Series ultrasound transducers with a
Model 340 Telemetry System.
Remind the patient to use the headset to check for continual pickup
of the fetal heart rate signal following each fetal movement.
FECG
You may need to tape the transducer cable to the patient to prevent
excessive tension on the legplate or attachment pad.
The recommended position for the legplate is on top of the upper
thigh instead of the inner thigh. This facilitates walking and
minimizes fluid contacting the legplate.
5-4 Model 340 Telemetry System Revision B

Monitoring via Telemetry: Monitoring Reminders
Tocotransducer
Remember to place the receiver’s UA Mode Selector switch in the
TOCO position.
When connecting or re-connecting a Corometrics Trimline
Tocotransducer to the transmitter’s UA connector, you must wait at
least 10 seconds before pressing the monitor’s UA Reference button. If
any device (monitor, receiver, transmitter is off), you must wait at
least ten seconds from the time the last device is powered on.
