2 Maintenance
2.1 Introduction
2.1.1 This chapter covers how to test the operation of the Rad-87 and
SatShare interface (if applicable), how to properly clean the Rad-
87 Pulse CO-Oximeter, how to recharge and replace the
batteries, how to replace the fuses, and how to obtain service
under normal operation. No internal adjustment or recalibration
is required. Service should be performed by qualified personnel
only. Safety checks should be performed at regular intervals or in
accordance with local and governmental regulations.
Note: Opening or repairing the Rad-8 Pulse Oximeter will void the
Masimo warranty. Products that require repair while under
warranty should always be returned to Masimo for warranty
service.
WARNING: ELECTRICAL SHOCK AND FLAMMABILITY HAZARD.
BEFORE CLEANING THE PULSE CO-OXIMETER,
ALWAYS
TURN THE UNIT OFF AND DISCONNECT THE POWER
CORD FROM THE BACK OF THE UNIT.
2.2 Cleaning
2.2.1 To clean the display panel use a cotton swab moistened with
70% isopropyl alcohol and gently wipe the panel.
2.2.2 To clean the outer surface of the Pulse CO-Oximeter, use a soft
cloth moistened with a 70% isopropyl alcohol. Do not allow
liquids to enter the interior of the instrument.
2.2.3 To decontaminate unit, refer to Section 6 .
CAUTIONS:
•Do not autoclave, pressure sterilize, or gas sterilize this Pulse CO-Oximeter.
•Do not soak or immerse the monitor in any liquid.
•Use the cleaning solution sparingly. Allow unit to air dry. Excessive solution
can flow into the monitor and cause damage to internal components.
•Do not touch, press, or rub the display panels with abrasive cleaning
compounds, instruments, brushes, rough-surface materials, or bring them
into contact with anything that could scratch the panel.

2-2 Rad-87 Signal Extraction Pulse CO-Oximeter Service Manual
•Do not use petroleum-based or acetone solutions, or other harsh solvents, to
clean the Pulse CO-Oximeter. These substances attack the instrument’s
materials and instrument failure can result.

3 Battery Operation and Maintenance
3.1 Overview
3.1.1 The Rad-87 Pulse CO-Oximeter uses a 6 volt, 1.4AHr lead acid,
sealed, rechargeable battery.
3.1.2 Please reference the Rad-87 Operator’s Manual for
specifications on battery charge time and capacity.
CAUTIONS:
•If the Rad-87 has not been charged for 1 month or more, then
recharge the battery prior to use.
•At low battery warning, connect the Rad-87 to AC power to prevent
interruption of power.
•Additional information on the Rad-87 batteries may be found in the
Rad-87 Operators Manual.
3.2 Replacing the Battery
3.2.1 Turn the Rad-87 off and remove the patient cable connection.
3.2.2 Place the unit on its side with the rubber footings facing up.
3.2.3 Remove the four screws from the housing assembly.
3.2.4 Carefully remove the speaker-side housing assembly. DO NOT
pull housing away as it may damage the speaker cable.
3.2.5 Remove the speaker connector from the system board and set
the housing aside.
3.2.6 Carefully lift the battery out of the housing and remove the
positive and negative battery connections.
3.2.7 Install the replacement battery. Verify proper positioning of the
(+) positive and (-) negative connectors. Reverse steps 3..3.1
through 3.3.6 to reassemble.
3.2.8 Verify the unit turns on, that all the LEDs momentarily light (AC
LED will not illuminate when powering on with battery power
only), that the low battery LED is not illuminated, and that the
unit stabilizes to a normal operation mode.
CAUTION: Follow local governing guidelines for proper disposal of the
internal battery. Do not incinerate.

3-2 Rad-87 Signal Extraction Pulse CO-Oximeter Service Manual
CAUTION: Do not over-tighten screws. Tighten the screws throughout
the Rad-87 to 80 in.- oz.
NOTE:It will be necessary to perform safety testing after replacement. Refer to
section 5.

4 Performance Verification
NOTE:Under normal operation, no internal adjustment or recalibration is
required.
4.1 Overview
4.1.1 To test the performance of the Rad-87 Pulse CO-Oximeter
following repairs or during routine maintenance, follow the
procedure outlined in this section. If the Rad-87 fails any of the
described tests, discontinue its use and correct the problem
before returning the unit back to the user.
4.2 Power-On Self-Test
4.2.1 With the Rad-87 plugged into an AC power source and no cable
or sensor plugged into the instrument, turn the monitor on by
depressing the Power Button. For about 2 seconds all available
LEDs are illuminated and a brief beep tone sounds. The unit will
then cycle through Saturation and Pulse Rate alarm limits on the
top LCD.
4.2.2 After this initialization “boot” cycle, the No Sensor, Alarm
Suspend and Normal Sensitivity Mode LED indicators will light.
Also, the SpO2 and BPM monitoring display will indicate “---“.
The Rad-87 is ready to begin normal operation.
4.2.3 Turn power off and then back on as many times as necessary to
verify this Power-On cycle.
4.3 Key Press Button Test
4.3.1 With the exception of the Power/Standby Button, press each soft
key button and verify that the Rad-87 acknowledges each key-
press with an audible beep tone or by indicating an associated
change on the display.
4.4 Alarm Suspend Indicator

parameter.
4.6.5 Repeat steps 4.6.1 to 4.6.3 with the Low and High Pulse Rate
Alarm parameter.
4.6.6 Reset the alarm limits again to the original settings and accept
the changes by pressing the Enter button.
4.7 Sensitivity Mode Test
4.7.1 Press the Sensitivity button to alternately light the APOD,
NORM, and MAX LEDs.
4.8 Button Volume Test
4.8.1 Press the Enter button x5. LED displays should show “but”, and
“VOL”.
4.8.2 Press the Up arrow button and cycle through the different
volume levels. Make sure the tone does not have a harsh or
raspy tone due to the speaker rattling in the plastic housing.
The tone heard should be louder with each press. Press the
DOWN arrow button and cycle through the different volume
levels. The tone heard should be quieter with each press. There
are three volume levels and volume off.
4.8.3 Return the volume to the factory default level 2.

& Pulse Rate numbers display.
4.10.5 Verify that the SpO
2
measurement is between 78% and 84%.
(with tester values of 81% +/- 3%)
4.10.6 Verify that the pulse rate measurement is between 60 bpm and
62 bpm (with tester values of 61 +/- 1 bpm).
4.10.7 Verify that the SpCO measurement is between 4% and 10%.
(with tester values of 7% +/- 3%)
4.10.8 Verify that the SpMet measurement is between 2.4% and 4.4%.
(with tester values of 3.4% +/- 1%)
4.10.9 Verify that an audible alarm occurs and that the SpO
2
measurement and the low SpO
2
alarm limit display are flashing
4.10.10 Press the Alarm Silence button once and verify that the alarm is
silenced.
4.10.11 Wait 120 seconds and verify that the alarm silence times out and
the audible alarm is activated again. Disable the Alarm before
continuing.

4-4 Rad-87 Signal Extraction Pulse CO-Oximeter Service Manual
4.10.12 Press the Up Arrow button several times and verify that the

Handheld.
4.11.2 Insert the non-dominant hand’s ring finger into the finger sensor.
4.11.3 PVI will fluctuate depending on motion, perfusion, physiology
and other factors, so there is no ‘normal’ value. If a number is
displayed, then the PVI feature is functioning properly.
4.12 Wireless Radio Testing (If Applicable)
4.12.1 Press and hold the Brightness button and the Down button for 5
seconds.
4.12.2 Use the Up and Down arrows to turn the wireless radio on.

network information, the LCD display will show the SSID, IP
Address, Subnet, Gateway, MAC Address, and Signal Strength
for 20 seconds.
4.13 Serial Port
4.13.1 The serial port outputs ASCII data using standard RS-232
protocol via a straight through serial cable.
4.13.2 Validation of the port can be done by connecting a serial printer
or using a PC with Hyper Terminal and the following setup:
4.13.3 Communication Parameters
