Troubleshooting Overview
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 m ake 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 cert ain 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”. I f the gel on the
electrodes is not mo i st, the electrodes are too
dry to get a good signal.
– Making certain the c onnections are not dirty.

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 an d the t ra nsmi tte r
is compromised due to dirt or corrosion. Remove
the leadset and make c ertain the leadset connector
in the top of the transmitter is not dirty or
corroded. If it is, clea n or replace the conn ector.
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). T hen change the lea dset. Check to
see if this fixes the problem.
If it does not, perform the fol lowing substeps:
a. Make certa i n 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 Fron t E nd Assembly).
b. Make cert ain that the 3/5 Lead Switch
connector is plugged-in prop er ly. If it is,
replace the ECG PCB.
c. If replacing the ECG PCB d oes not resolve the
problem, replace the Front End Assembly.
TRANSMITTER OFF INO
If there is a TRANSMITTER OFF message at the central
station, this ind i cat es th a t th e t ra nsmitter has determined
that there has been a
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 Problems
INVALID LEADSET INOP
This indicates that the transmitter has either detected a
4-wire leadset or an EASI
leadset attached. Do the following:
1. If a 4-wire leadset has been installed, monit oring is
not possible. Replace wit h 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 EASIä ECG transmitter, a
5-wire must be used.
2. If the transmitter i s an EA S Iä ECG 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 EASI
configuration of the EASI parame te r using the
transmitter Service Tool or Wave Viewer, as
follows:
ä ECG transmitter has a 3-wire
ä transmitter. Check the
– 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 simulat or. 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, th e transmitte r is co nfigured
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.
Transmitter Non-RF Application

4. If the problem is not solv ed by Steps 1 - 3, then
there may be a problem wit h the leadset switches
not being detect ed 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
INOP at the Central Station). Replace the Main PCB.

Normally, either one of these INOP messages simply
indicat es the need to replace the battery in the
transmi tter generating the message. But, if the battery is
replaced and the me ssage still occurs, do the fo llowing.
Note
Battery life depends on the transmitter being used, the
battery type, and the SpO2 sample rate (SpO
monitored). Refer to the spec ifications in

6. If the problem persists, replace the Main PCB.
SpO2 ERRATIC INOP
This INOP indicates that the SpO2 measurem ents are
erratic. This could be due to a faulty transducer or
incorrect positioning of the transducer . It could also be
caused by optical shun ting if the transducer is too big or
too small. If this INOP appears, do the fo llowing.
1. Verify that the transducer is appropriate for the
patient’s weight. If not, use a different transduc er
with the correct fit.

Transmitter SpO2 Problems
2. Make certain that the light source and photo
detector are opposite each other and that the light
passes through the ateriolar bed.
3. Reposition the transducer to a site with higher
perfusion.
4. Replace the transducer.
5. Replace the adapter cable.
SpO2 INTERFERENCE INOP
This INOP can be caused if the level of ambient light is so
high that the SpO
pulse rate. It can also be caused by an equipment
malfunction. If this INOP appea rs, do t he following.
1. Cover the transducer with a non-white opaque
material (e.g., pulse oximete r probe wraps - Posey
wrap or equivalent). If it does not solve the
problem, continue.

2. Replace the transducer.
3. Replace the adapter cable.
4. This problem can also be caused by electrical
interference. Reduce or remove any sources of
electrical interference.
SpO2 NO TRANSDUCER INOP
This INOP can occur if the SpO2 transducer is
disconnected, dirty , o r broken. It can also be caused by a
transmitter failure. If this INOP appears, do the following.
1. If the transducer is disconnected, reconnect the
transducer.
2. Replace the transducer.
3. Replace the SpO

Transmitter SpO2 Problems
13
SpO2 NOISY SIGNAL INOP
This INOP can be caused by excessive patient movement
or electrical interference, which is seen as irregular pulse
patterns. If this INOP appears, do the following.
1. Move the transducer to a site with less movement.
2. Reduce or remove any sources of electrical
interference.
SpO2 NON-PULSATILE INOP
This INOP can be caused by a weak or non-detectable
pulse. Try the following to see if they resolve the
problem:
1. Relocate the sensor to a site with improved
circulation.
2. Warm the area to improve the circulation.
3. Try another sensor type.
SpO2 TRANS MALF INOP
This indicates that the SpO2 transducer is
malfunctioning . Do the following:

NO DATA FROM BED INOP
This INOP indicates that no information is getting to the
central station for a particular transmitter-receiver pair.
To effectively troubleshoot this problem, receiver
mainframe communica tion with the SDN must be
verified. This communication link determines the course
of action. However, there is another possibility to
consider before re-booting the mainframe. If the
telemetry system is being used with a Philips Information
Center, make certain that the telemetry bed or beds are

means th at the problem is elsewhere. Do the following to
help isolate where the problem lies.
1. Check the SDN cable t o see if it is miss i ng or
defective. If it is, replace or install a new one as
required.
2. Make certain there are not duplicate SDN beds. If
there are , reconfig ure the receiver mainframe for
other branch es or move one bedside to another
branch.
3. Make certain that two receiver mainframes do not
have identical SDN Unit numbers. If they do,
reconfigure one receiver mainframe with another
SDN unit number.
4. If it is a non-SCC system, an SDC cable may have
been used instead of an LDC cable. Check the cable
to make certain an LDC cable is being used.
5. The breakaway board portion of the SDN board
could be broken. Replace the SDN board.
