Identify Rad-97 Version
Two (2) versions of the Rad-97 device exist. The following procedure provides instructions for determining the version of the Rad-97. Determining the version of a Rad-97
determines how to follow the proper procedures for the device being serviced.
A simple way determine the version of the Rad-97 device is to look at the vents at the rear of the device:
•Version 1 - The back of the device has three columns of vents.
•Version 2 - The back of the device has two columns of vents.

Masimo Corporation 11 www.masimo.com
Chapter 1: Maintenance Procedures
This chapter covers how to properly clean Rad-97.
WARNING: Electrical shock and flammability hazard. Before cleaning Rad-97, always turn the unit off and disconnect the power cord from the back of the unit.
CAUTION: Do not autoclave, pressure sterilize, or gas sterilize Rad-97.
CAUTION: Do not soak or immerse Rad-97 in any liquid.
CAUTION: Use the cleaning solution sparingly. Allow unit to air dry. Excessive solution can flow into Rad-97 and cause damage to internal components.
CAUTION: 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.
CAUTION: Do not use petroleum-based or acetone solutions, or other harsh solvents, to clean Rad-97. These substances attack the device’s materials and device failure
can result.
Cleaning
Rad-97 is a non-sterile and reusable device. The surface of the Rad-97 should be cleaned when the device is visibly dirty, before and after each procedure, and/or according
to hospital practice.
Do not allow liquids to enter the interior of Rad-97. Using the recommended cleaning solutions on the touchscreen will not affect the performance of Rad-97.
To clean the device:
1. Disconnect the AC Power Supply and ensure the sensor is not applied to the patient.
2. Wipe the outer surfaces using a dampened soft cloth with one of the recommended cleaning solutions twice or until the surfaces are free of any visible residue.
3. Dry the device thoroughly prior to using on a patient.
The surfaces of the Rad-97 may be cleaned with the following solvents or cleaning agents:
•70% Isopropyl Alcohol
•Glutaraldehyde
•10% bleach (5% - 5.25% sodium hypochlorite) to 90% water solution
•Quaternary ammonium chloride solutions
•0.5% hydrogen peroxide
CAUTION: Do not use undiluted bleach (5% - 5.25% sodium hypochlorite) or any cleaning solution other than those recommended here because permanent damage to the
device may occur.
CAUTION: To prevent damage, do not soak or immerse the device in any liquid solution.
CAUTION: Do not sterilize by irradiation, steam, and autoclave or ethylene oxide.
Vent Cleaning
The following procedure applies to Version 1 of Rad-97. Version 2 does not have these vents.
Vents may be cleaned using a small vacuum with brush attachment.
To clean, vacuum over the vents using a brush attachment, if available, to clear any debris.

Battery Removal (Version 1)
1. Disassemble the Rad-97 as instructed in Disassembly on page 15.
2. On Rad-97 with NomoLine Capnography, disconnect the capnography module electrical connector.
3. Lift the faceplate upwards from the case to disengage from the plastic T connections.
•For Rad-97 with noninvasive blood pressure, the NIBP tube can remain connected during the battery replacement procedure.
•For Rad-97 with NomoLine Capnography, the tubing will remain connected during the battery replacement procedure. Lift the faceplate very gently upwards
to disengage from the plastic T connections. Do not force the front assembly upwards. The capnography module will hit the rest of the assembly if forced.
Once the plastic T connections are disengaged, move the front assembly away from the rest of the assembly, being careful not to hit the capnography module
against anything or to disconnect the capnography tubing by pulling the front assembly too far away from the rest of the assembly.
CAUTION: Use care not to pull the bezel off of the faceplate when removing from the case.
