Introduction
Some customers may experience limited battery life in their Smart Keys. The Smart Key "wakes up" by receiving a "ping" or electronic noise. Many electronic devices emit a "ping" or electronic noise, therefore the Smart Key(s) could wake up resulting in reduced battery life.
If the Smart Key(s) is stored near any of the following components, battery life may be reduced:
^ TVs or computer monitors
^ DVD or VCR units
^ Desktop PCs or notebooks
^ Cordless phones or cell phones
^ Microwave ovens or other electronic cooking appliances
^ Modems
^ Certain lighting fixtures
NOTE
It is recommended to keep the Smart Key(s) at least one meter (40 inches) from these electronic devices.
