Transmitter Non-RF Application 5
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.

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.
quickref.fm Page 6 Wednesday, June 5, 2002 3:08 PM

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.

Transmitter Non-RF Application 9
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.
quickref.fm Page 10 Wednesday, June 5, 2002 3:08 PM

Transmitter Non-RF Application 11
ECG EQUIP MALF INOP
This INOP indicates that either a software incompatibility
has been found or a fault has been detected in the ECG
hardware in the transmitter.
1. If the transmitter is an EASIäECG transmitter, this
INOP indicates that the software in either the
receiver mainframe or the central station cannot
process EASIäECG data. Do one of the following:
a. Update the software in the receiver mainframe and
the central station to a compatible revision.
b. Downgrade the transmitter firmware to a revision
compatible with the mainframe and central station
2. If SpO2, cannot be monitored, replace the ECG
PCB.
3. If changing the ECG PCB does not correct the
problem, replace the Main PCB.
TRANSMITTER MALF INOP
This INOP indicates that the self-test has discovered a
problem with the internal, non-RF circuitry of the
transmitter. The problem probably liesin the Digital ASIC
or the RAM section of the Main PCB. If this INOP
appears, replace the Main PCB.
ARRHY REQUIRED INOP
This message indicates that arrhythmia monitoring has
been turned off for an EASI ECG transmitter.
1. Turn arrhythmia monitoring ON at the Information
Center.
2. If arrhythmia monitoring is not desired, then a
standard ECG transmitter must be used.

Transmitter SpO2 Problems
12
Transmitter SpO2Problems
SpO2EQUIP MALF INOP
This INOP indicates there is a problem with the SpO2
circuits associated with the transmitter. The following
procedure describes how to troubleshoot this problem:
1. The transducer may be bad. Change the transducer
to see if this resolves the problem.
2. The SpO2 adapter cable may be faulty. Replace the
cable to see if this fixes the problem.
3. Open the transmitter and make certain the SpO2
Connector cable is connected to the SpO2Board.
Make certain it is not damaged. If the cable is
damaged, replace the Front End Assembly.
4. Make certain that the Main PCB to SpO2Board
ribbon cable is connected properly and is not
damaged. If the cable is damaged, replace the Main
PCB.
5. Replace the SpO2Board.
6. If the problem persists, replace the Main PCB.
SpO2ERRATIC INOP
This INOP indicates that the SpO2measurements are
erratic. This could be due to a faulty transducer or
incorrect positioning of the transducer. It could also be
caused by optical shunting if the transducer is too big or
too small. If this INOP appears, do the following.
1. Verify that the transducer is appropriate for the
patient’s weight. If not, use a different transducer
with the correct fit.
quickref.fm Page 12 Wednesday, June 5, 2002 3:08 PM

Transmitter SpO2 Problems 13
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 SpO2transducer cannot measure SpO2or
pulse rate. It can also be caused by an equipment
malfunction. If this INOP appears, do the following.
1. Cover the transducer with a non-white opaque
material (e.g., pulse oximeter 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.
SpO2NO TRANSDUCER INOP
This INOP can occur if the SpO2transducer is
disconnected, dirty, or 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 SpO2 Board.
quickref.fm Page 13 Wednesday, June 5, 2002 3:08 PM

Transmitter SpO2 Problems
14
SpO2NOISY 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.
SpO2NON-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.
SpO2TRANS MALF INOP
This indicates that the SpO2transducer is
malfunctioning. Do the following:
1. Check to see if the SpO2connector on the
transducer or transmitter is dirty or corroded.
Clean them if required.
2. Replace the transducer or adaptor cable.
3. Replace the Front-end Assembly.

Receiver Mainframe/System Faults 15
Receiver Mainframe/System Faults
Power does not come on when Receiver
Mainframe Power On/Off Button is pressed
1. The receiver mainframe power cord may be
disconnected or connected to a bad source. Make
certain that the power cord is plugged into the
correct power source.
2. Check the power-on LED on the rear of the
Mainframe to see if it is lighted.
3. The power supply may be bad. Replace the power
supply.
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 communication 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
not in Standby Mode.
If the beds are in Standby Mode this INOP is generated.
Take the beds out of Standby Mode and the problem
should disappear.
If NO DATA FROM BED INOPS occur intermittently,
check the mainframe status logs for error codes. See
Chapter 2 in the Service and Reference Guide for
information on how to access the logs and Appendix E of
that manual for the error codes.

1. Check the overall operation of the receiver
mainframe by re-booting it and observing the LEDs
on the 40 MHz CPC card and the Utility CPU board.
To re-boot the mainframe, push the power button
to remove power and then push it again to restore
power. See Figure 3 for the Receiver Mainframe
Board location.

Receiver Mainframe/System Faults 17
If the normal bootstrap sequence occurs, receiver
mainframe hardware is probably working correctly. This
means that the problem is elsewhere. Do the following to
help isolate where the problem lies.
1. Check the SDN cable to see if it is missing 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, reconfigure the receiver mainframe for
other branches 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.

If an abnormal bootstrap sequence occurs, then the
problem lies in the receiver mainframe. To troubleshoot
the mainframe, do the following:
1. Remove power to the receiver mainframe and
remove the 40 MHz CPC Card. Re-apply power to
the receiver mainframe and observe the following
LED pattern on the Utility CPU during the
bootstrap routine:
2. If the sequence in the table occurs, following is the
probable cause of the problem.
a. Refer to the Philips Telemetry System
Compatibility Matrix Service Note to verify the
compatibility between the Utility CPU and the
CPC PCB.
b. The 40 MHz CPC Card was in the wrong slot.
Check the correct card placement and insert
the CPC Card into the correct slot. The CPC
belongs in the 4th slot from the left in the rear
of the mainframe. See Figure 3 on page 16.
c. The 40 MHz CPC Card is faulty. Replace it.

3. If the sequence does not occur, do the following:
a. Remove the SDN board and re-initialize the
receiver mainframe. If the sequence occurs,
replace the SDN board.
b. Remove the Rack Interface board and re-
initialize the receiver mainframe.
If the sequence occurs, replace the Rack

Receiver, Non-RF Problems
NO RECEIVER INOP
This INOP is generated when the telemetry system does
not detect a receiver present for a configured receiver
slot. This problem can occur in two ways -- in all or
multiple channels or in a single channel. Depending on
whether multiple or single channels are affected, the
actions are different. If this INOP appears, do the
following.
If the problem is in a single-channel...
1. Check and see if the receiver module for the
reporting slot is seated properly. If it is not, re-seat
the module.
2. The receiver mainframe may be configured for
receivers that do not exist. These are empty
receiver slots with SDN branch assignments. Do the
following to see if this resolves the problem.
a. Check the configuration at the Central Station
using the Telemetry Service Screen.
b. Using the Telemetry Service Tool, reconfigure the
receiver mainframe. For any empty receiver slots,
assign a “0” to the SDN Branch Number.
3. The receiver module of the reporting channel is
faulty. Replace the receiver module.
4. Check to see if the rack interface to receiver
backplane cable is disconnected or broken.
Replace the cable if it is broken.
5. The receiver backplane is faulty. Replace the
receiver backplane.
