• Dispose of used battery promptly in accordance with local regulations (place in
plastic bag and recycle if possible).
• Do not insert batteries with the and polarities reversed.
• Do not short-circuit.
• Be sure to wrap each battery when disposing or storing to avoid short circuit.
• If leaked liquid gets in the eyes, wash them with clean water and consult a
physician immediately.
• Do not use new and used batteries together. Do not use different types of
batteries together.
• Do not apply strong pressure to the batteries nor handle roughly.

2.3. Calibrating the WPT
Remove the front cover of the WPT and make sure that the WPT is acclimatized to the
ambient temperature.
NOTE: Keep hands and breathe away from the WPT to minimize calibration error.
NOTE: The black throttling range adjuster has been factory set to the location marked
on the lever as shown in Figure 6. The factory setting provides a Throttling
Range (TR) of 4°F. This TR adjuster MUST NOT BE MO VED to ensure proper
operation and accuracy of the WPT.
