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 instrument. The battery compartment is accessed from the back of the intrument. 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 the instrument. Remove the batteries
and install new batteries in the directions indicated by the battery icons inside the battery compartment.
Replace the battery cover by sliding it back up from the bottom of the instrument until the rectangular
locking button snaps back into position.
WARNING: FAILURE TO REPLACE BATTERIES PROMPTLY AFTER A LOW
BATTERY ALARM MAY RESULT IN THE CO-OXIMETER SHUTTING DOWN AND
LEAVING THE PATIENT IN AN UNMONITORED CONDITION.
WARNING: USE ONLY ALKALINE BATTERIES. USE OF NON ALKALINE
BATTERIES MAY AFFECT THE ACCURACY OF THE BATTERY LEVEL METER.
WARNING: USE OF BATTERIES WITH A CELL VOLTAGE OF MORE THAN 1.5V
COULD CAUSE DAMAGE TO THE RAD-57.
WARNING: EFFECTIVE BATTERY LIFE WILL BE REDUCED WHEN OPERATING
THE INSTRUMENT BELOW 5ºF (-15º C) DUE TO ALKALINE BATTERY
TECHNOLOGY.
Battery charge level is indicated by four LED indicators at the bottom of the front panel. All four
indicators will be lit when the batteries are full, with fewer indicators being lit as the batteries lose their
charge. When less than ten (10) percent battery life remains, the final battery indicator will begin to
flash and an audible alarm will sound.
Be sure to follow local regulations in regards to battery disposal.
