Figure 8. Low Battery Message
Critically Low Battery
If the Control Unit is operating on battery power and the battery charge level is 5% or
less, the critically low battery message with an alert icon displays and an audible alert
sounds. The percentage of remaining charge and the battery gauge with a red bar in
the upper right corner of the display indicates the level of battery charge. Ultrasound
runtime for each channel is displayed during a critically low battery notification.
Immediately connect the Control Unit to AC power to prevent the unit from automatically
shutting down in 3 minutes. A countdown timer is displayed indicating how much time
remains before the Control Unit will shut down (see Figure 9).
