(lose power) over time, especially in warm
environments. Leaving the battery in a
discharged state may result in permanent
battery damage. To ensure satisfactory
performance and avoid permanent damage,
charge the internal battery every month.
Check for poor connection to
battery and frame. Make sure
connection points are clean.
