8.5 End of Transmitter Battery
How do you know if your transmitter’s battery will last through your next
session?
System messages help you determine if your transmitter’s battery will last
through your next seven-day session. Starting at three weeks prior to the end
of its battery life, the messages count down the transmitter’s battery until it
has only seven days. If the transmitter battery has seven days or less
remaining, you won’t be able to start a new session.
