Transmitter Non-RF Application
Problems
LEADS OFF INOP
This INOP generally means that one of the patient leads
has fallen off the patient. It can also indicate a fault
within the transmitter.
1. A lead may have become disconnected from the
electrode. Go to the transmitter generating the
INOP and make certain that all leads are connected
to the electrodes on the patient’s body. The LEDs
on the front of the transmitter should be off if all
lead wires are attached properly.
If the leads are correctly connected, use the
Telemetry Service Tool or Wave Viewer at the
bedside to make certain there is a good waveform.
The transmitter can also be connected to a patient
simulator, if this is more convenient. Using the
Telemetry Service Tool or Wave Viewer, check the
following:
a. All available leads. If there is an ECG waveform
but no LEADS OFF-Check Transmitter INOP
on the Telemetry Service Tool or Wave Viewer,
the leads are connected.
b. If there is not a good waveform, check the leads
again and make certain they are applied properly
before continuing with the procedures. Proper
application of electrodes includes:
– Proper skin preparation.
– Using “moist electrodes”. If the gel on the
electrodes is not moist, the electrodes are too
dry to get a good signal.
– Making certain the connections are not dirty.

Transmitter Non-RF Application Problems

2. If all leads are connected and there is not a good
signal, there may be a broken lead wire or the
connection between the leadset and the transmitter
is compromised due to dirt or corrosion. Remove
the leadset and make certain the leadset connector
in the top of the transmitter is not dirty or
corroded. If it is, clean or replace the connector.
If there is no dirt or corrosion, check that a leadset
with a telemetry leadset combiner block with latch
is used. Attach the leadset, (the leadset will click
when it locks). Then change the leadset. Check to
see if this fixes the problem.
If it does not, perform the following substeps:
a. Make certain the Front End Assembly to the
ECG PCB cable is connected (red tab
connector) properly or not broken. If the cable
is broken, replace the defective assembly
(ECG PCB or Front End Assembly).
b. Make certain that the 3/5 Lead Switch
connector is plugged-in properly. If it is,
replace the ECG PCB.
c. If replacing the ECG PCB does not resolve the
problem, replace the Front End Assembly.
TRANSMITTER OFF INO
If there is a TRANSMITTER OFF message at the central
station, this indicates that the transmitter has determined
that there has been a LEADS OFF condition on all leads
for the last 10 minutes or longer and has gone into RF
auto-shutoff.
1. Re-attach the leads to the patient. The transmitter
will turn on automatically.

Transmitter Non-RF Application 7
INVALID LEADSET INOP
This indicates that the transmitter has either detected a
4-wire leadset or an EASIäECG transmitter has a 3-wire
leadset attached. Do the following:
1. If a 4-wire leadset has been installed, monitoring is
not possible. Replace with a 3- or 5 wire leadset.
a. If the transmitter is a standard ECG transmitter,
replace with a 3- or 5-wire leadset.
b. If the transmitter is an EASIäECG transmitter, a
5-wire must be used.
2. If the transmitter is an EASIäECG transmitter, this
INOP will appear if monitoring is attempted while a
3-wire leadset is attached to the transmitter. Attach
a 5-wire leadset.
3. If this is a standard ECG transmitter, it may be
configured as an EASIätransmitter. Check the
configuration of the EASI parameter using the
transmitter Service Tool or Wave Viewer, as
follows:
– Telemetry Service Tool: Connect the service
tool to the transmitter and move to
Transmitter Configuration Screen Two
– Wave Viewer: Connect a 5-wire leadset to the
transmitter and to an ECG simulator. Establish
communication between the Wave Viewer and
the transmitter. If the ECG waveform is
labelled EASI and has the lead selections of
AI, AS and ES, the transmitter is configured
for EASI operation. If the ECG waveform is
labelled Lead and has the lead selections: I, II,
III, aVR, aVL, aVF, MCL and V, the transmitter
is configured for standard ECG.
– If the transmitter is configured incorrectly,
reconfigure it using the Service Tool.

4. If the problem is not solved by Steps 1 - 3, then
there may be a problem with the leadset switches
not being detected properly.
a. Check where the leadset attaches for dirt and clean
as necessary. Leadset switches are located next to
the reference and chest (standard ECG) or
reference and “E” (EASI) lead wires.
b. The 3/5 lead switch may not be connected to the
ECG PCB properly.
c. Replace the Front-End Assembly
d. Replace the Main PCB.
NO SIGNAL INOP and an RF OUT OF LOCK
INOP at Telemetry Service Tool or Wave
Viewer
This INOP means that the transmitter has determined
that the phase-lock loop in the transmitter is no longer
functioning (This condition also generates a NO SIGNAL
INOP at the Central Station). Replace the Main PCB.

Battery INOPs
This module tells how to deal with INOPs related to
battery operation. These INOPs are:
BATTERY WEAK
REPLACE BATTERY
Normally, either one of these INOP messages simply
indicates the need to replace the battery in the
transmitter generating the message. But, if the battery is
replaced and the message still occurs, do the following.
Note
Battery life depends on the transmitter being used, the
battery type, and the SpO2 sample rate (SpO2is being
monitored). Refer to the specifications in Appendix A of
the Service and Reference Guide to determine what
battery life to expect.
If the battery life is less than expected, things to check
are:
• Remember that simply unplugging the SpO2
transducer and turning SpO2off at the central does
not shut off the SpO2sampling. The sampling rate
must be set to Manual using the Telemetry Service
Tool or Wave Viewer.
• After making a manual SpO2measurement using
the Telemetry Service Tool or Wave Viewer,
terminate the measurement by selecting End STAT;
otherwise, the SpO2function does not shut off.
• Remove the batteries from the transmitter when
they are not in use. The RF auto-shutoff feature
does not save battery life because the circuitry is
constantly checking to see if the unit has been
connected to a patient.

Transmitter Non-RF Application Problems
10
1. The battery could be inserted improperly. Check
that the terminals of the battery are oriented
correctly with the battery contacts.
2. Open the battery door and check the battery
contacts. If they are corroded, clean them. If they
appear damaged, replace the battery contacts.
Also, check the screws that connect the battery
contacts to the Case Assembly.
3. Zinc-air batteries cannot be used in transmitters
with SpO2hardware because zinc-air batteries
cannot reliably supply enough current at start-up of
the transmitter to make sure the transmitter
functions properly. Even if SpO2is not being
monitored, if the transmitter has the SpO2
hardware installed, a zinc-air battery cannot be
used. A lithium or alkaline battery must be used.
4. Remove the battery and separate the case assembly
from the transmitter’s internal electronics. Using an
ohmmeter, check the resistance from the battery
contact inside the case to its corresponding
external battery contact. The resistance should be
less than 1 ohm. If it is not, replace the battery
contacts.
5. SpO2might be affecting the battery. Replace the
SpO2PCB.
