Safety Guidelines
Battery Power
Use the transmitter only when necessary.
Every time a button is pressed, the remote
engine starter is consuming battery power.
If the battery is low on power, the
transmitting range of the remote engine
starter will be affected. Check the battery
periodically, and replace it when necessary.
For battery replacement refer to page 35.

In Case of Loss
If one of your transmitters is ever lost, contact your local Honda
dealer for a replacement. Your system will be reprogrammed to
prevent the lost transmitter from operating your system. If your
system needs reprogramming due to a lost transmitter, you must
bring in any additional remotes for reprogramming at this time.
