CHAPTER 11: IMPORTANT PRECAUTIONS and NOTES
• Keep eyes on the road. Do not become overly engaged with display.
• We recommend getting familiar with the computer functions while stationary.
• The computer and chest strap are water resistant, not waterproof. Avoid sustained water
contact and do not deliberately place in water or under high-pressure sprays.
• Avoid spraying the unit directly with solvent. Do not use thinner or other solvents to
clean parts.
• Failure to adhere to these precautions may cause premature failure or incorrect
operation of the unit and may void the warranty.
Other Important Notes:
• Battery Life: The Joule GPS has a rechargeable battery that will last a significant amount
of time when fully charged. However, some features of the Joule will use more power
then others:
- Displaying the Navigation dashboard for extended periods of time can impact
battery life. A lot of processing power is required to keep the live map display up to
date.
- Setting the backlight to “always on” will impact battery life, although the Joule is
still very efficient in terms of power usage when the backlight is in use.
- Setting the backlight time out to a long period of time (something more then 30
seconds) will impact battery life, depending on how often buttons are pushed,
causing the backlight to go on.
- Setting the Smart Backlight option could impact battery life if a significant amount
of time is spent using the device at night.
• GPS signal lock time can vary depending on environmental conditions.
See Appendix D for more detailed information on GPS signal locking.
