5.2.3 Removing the Micro-Fuel Cell

The Micro-Fuel cell is located inside the nylon Probe behind the front panel. (See Figure 5-1.) To remove an existing cell:

1.Remove power to the instrument by unplugging the power cord at the power source.

2.Open the front panel door by pressing the release button on the top right corner of the door all the way in and releasing it.

3.Pull up on the nylon Probe, with a slight rocking motion, to release it from the Probe Receptacle.

4.Do Not remove the O-rings unless they are worn and no longer hold the Probe tightly. (If worn, replace them.)

5.When it is free, unscrew the Cap from the nylon Probe. Hold the Probe vertically to prevent dropping the cell out of the probe.

6.Remove the Cell from the Probe, and dispose of it in an environmentally safe manner.
