grounded; otherwise, static charges from your body could
damage the electronics. Such damage is not covered by the
warranty Grounding straps and kits are available from
electronics suppliers.

Replacing the ALTAIR Pro Battery

1. Remove the four screws securing the case halves together after
the instrument is turned OFF (except Steel Mill version).
2. Carefully remove the front cover to expose the battery.
• The circuit board will remain with the back half of the case.
• Do not touch the display connections (two blue connectors)
3. Remove the depleted battery and replace only with one specified in
TABLE 6-2.
• Be sure to observe proper polarity on the battery,
as shown on the battery holder.
4. Replace the front cover, making sure the sensor, horn gasket and
sensor gasket are properly seated. For the Remote O 2 instrument
only, ensure that sensor pins located on the front case align with
the circuit board sockets in the back case.
5. Ensure the interface and connectors for the display are clean and
free of dirt for proper operation.
• If needed, clean display connectors with a soft, lint free cloth.
6. Replace the four screws.
NOTES:
• Changing instrument battery can result in lost time in the Data log.
• After changing batteries, verify the Time and Date with your PC via
the IR mode and the FiveStar Link. See Chapter 2 for more details
on entering IR mode. Once the instrument is communicating via IR
and the FiveStar link, the instrument time automatically
synchronizes with the PC.
• The time and date is based on the PC time and date. Ensure the
PC is correct before communicating with the instrument.
Do not over-tighten screws; otherwise, case may be damaged.
