Real Time Clock Battery Maintenance - Thermo Scientific Orion DUAL STAR User Manual

Real Time Clock Battery Maintenance

The Orion DUAL STAR meter uses an internal BR-1225 type, 3 V lithium coin cell
battery for real time clock operation . If the real time clock function is lost, the
battery needs to be replaced . Since the battery is inside of the meter housing,
only qualified technicians should attempt to replace the battery .
Replacing and Disposing of the Battery
1 . Disconnect the universal power adapter from the meter and the wall outlet .
2 . Orientate the meter so the display is facedown on a soft, nonmetallic, non-
scratching surface . The bottom of the meter (with the pullout guide) should be
closest to you and the top of the meter (with the electrode and cable inputs)
should be farthest from you .
3 . Use a medium size Phillips head screwdriver to unscrew the four screws on
the back of the meter . Remove the back cover of the meter . Be careful not to
spill any liquids, dust or other foreign matter onto the exposed circuit board .
4 . Locate the battery holder . It is a round, small, coin size battery holder that
is located in the left bottom corner of the circuit board and has a reference
designator BAT41 marked in white on the circuit board .
5 . Use a small flat screwdriver to pry out the battery from the holder . Slide the
new battery, from the side, into the battery holder and be careful not to break
the metal tab that holds the battery in place .
6 . Place the back cover on the meter and fasten the screws .
7 . Dispose of the used battery in safe and environmentally responsible way,
following all applicable federal, state and local regulations .
Important Note: Replace the battery only with a new BR-1225 type, 3 V
lithium coin cell battery. Do not substitute any other battery type.
