, SpCO and pulse rate accuracy, unless
otherwise specified in the tables above.
Accuracy specified when used with Masimo Rainbow SET technology pulse CO-Oximetry
monitors or with licensed Masimo SET pulse oximetry modules during no motion. Numbers
represent ± 1 standard deviation. Plus or minus one standard deviation represents 68%

240bpm. Carboxyhemoglobin accuracy (SpCO) from 1 to 40%.
CLEANING AND REUSE OF MASIMO REUSABLE SENSORS AND CABLES
Reusable sensors and patient cables can be cleaned per the following procedure:
■ Remove the sensor from the patient.
■ Disconnect the sensor from the patient cable.
■ Disconnect the patient cable from the monitor.
■ Wipe the entire sensor and/or patient cable clean with a 70% isopropyl alcohol pad.
■ Allow to air dry thoroughly before returning it to operation.
CAUTION: CAREFULLY ROUTE PATIENT CABLES TO REDUCE THE POSSIBILITY OF
PATIENT ENTANGLEMENT OR STRANGULATION.
REATTACHMENT OF SINGLE USE ADHESIVE SENSORS
■ LNOP single use sensors may be reapplied to the same patient if the emitter and
detector windows are clear and the adhesive still adheres to the skin.
■ The adhesive can be partially rejuvenated by wiping with a 70% isopropyl alcohol
wipe and allowing the sensor to thoroughly air dry prior to replacement on the patient.
NOTE: If the sensor fails to track the pulse consistently, the sensors may be incorrectly
positioned. Reposition the sensor or choose a different monitoring site.
CAUTION: DO NOT REPROCESS ANY MASIMO SINGLE USE SENSORS.

Introduction
This chapter covers how to test the operation of the Rad-57, how to properly clean the Rad-
57 Pulse CO-Oximeter, how to replace the batteries and how to obtain service.
Under normal operation, no internal adjustment or recalibration is required.
WARNING: BEFORE CLEANING THE OXIMETER, ALWAYS TURN IT OFF AND
REMOVE THE BATTERIES.
Cleaning
To clean the display panel, use a cotton swab moistened with 70% isopropyl alcohol and
gently wipe the panel.
To clean the outer surface of the oximeter, use a soft cloth dampened with a mild soap and
water. Do not allow liquids to enter the interior of the instrument.
CAUTIONS:
■ DO NOT AUTOCLAVE, PRESSURE STERILIZE, OR GAS STERILIZE THIS
OXIMETER.
■ DO NOT SOAK OR IMMERSE THE MONITOR IN ANY LIQUID.
■ USE THE CLEANING SOLUTION SPARINGLY. 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.
■ DO NOT USE PETROLEUM-BASED OR ACETONE SOLUTIONS, OR OTHER
HARSH SOLVENTS, TO CLEAN THE OXIMETER. THESE SUBSTANCES
ATTACK THE DEVICE’S MATERIALS AND DEVICE FAILURE CAN RESULT.
Refer to Section 8, Cleaning and Reuse of Masimo Reusable Sensors and Cables for
cleaning instructions of the sensor and patient cables.
BATTERY REPLACEMENT
The Rad-57 is powered by 4 “AA” alkaline batteries. Do not use any other type of batteries
or power source to run the device. The battery compartment is accessed from the back of
the device. To replace the batteries first remove the battery cover by depressing the small
rectangular button at the bottom of the cover, and sliding the cover down off the bottom of
