Battery Replacement
The M1 uses one 1.5 volt AA battery. The battery compartment can
be opened by pulling outward from the indentation on back of the
device (see Figure 7). The old battery may be removed by turning
the device with the opening facing down and tapping the device
lightly on your hand to shake the battery free. The new battery
should be replaced with the negative side pressed upon the
battery contact containing a spring. Close the battery
compartment door to secure the battery. A fresh alkaline battery
should power the device for at least 8 hours of continuous use.

The current version of the software can be viewed by pressing and holding down the “Mode” button. The
“Information Screen” will be displayed until the “Mode” button is released. The version is displayed as

Cleaning the Reusable Sensor
Cautions:
•
Clean the sensor before applying it to a new patient.
•
Unplug the sensor from the M1 before cleaning.
•
Do not sterilize, autoclave, or immerse the sensors in liquid of any kind. Do not pour or spray any
liquids into the sensor. Do not sterilize with EtO.
•
Do not use caustic or abrasive cleaning agents on the sensors. Do not use cleaning agents
containing ammonium chloride or isopropyl alcohol.
Cleaning Method:
1.
To clean the sensor, wipe all patient contact surfaces with a soft cloth dampened with a mild
detergent or a 10% bleach/90% water solution (household bleach [containing less than 10%
sodium hypochlorite]).
2.
Allow the sensor to dry thoroughly before reusing.
Note: Do not open the sensor’s case more than 90°, or the case may be
damaged. The figure at right shows the appropriate opening of the case for
cleaning (see Figure 8).
Note: To minimize cable deterioration when cleaning the cable, gently wipe
away from the plug end towards the sensor end.
