8.5 End of Transmitter Battery
How do you know if your transmitter battery will last through your next session?
System messages help you determine if your transmitter 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 battery life 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.
