Conserving Power

There are many ways the scanner can be shut down, both manually and automatically.

If the scanner LED is off, then the device is off and consuming minimal power while the battery is inserted. In this state, the scanner will run the Bluetooth beacon for approximately 10 days with a fully charged battery.

If the scanner LED is on (any color), then the device is on and core circuitry is consuming power. While imaging, the scanner will run for up to 60 minutes with a fully charged battery; when not imaging, the scanner will remain on for up to 4 hours with a fully charged battery.

If you turn on the scanner and leave it untouched, it will go through the following modes to help reduce battery power and temperature:

1. After three seconds, it decreases frame rate.
2. After 30 seconds of decreased frame rate, it freezes.
3. After 10 seconds in freeze mode, it goes idle.
4. After 15 minutes of idle time, it shuts down.

Physical Shut Off

Depending on the scanner device, multiple physical shut off methods can be used:

1. On Clarius HD and HD3 devices, the Down button default is programmed to shut the device off after a 3-second hold.
2. On all devices, the battery can be safely removed while powered.

Interface Shut Off

After a scanner has been selected (automatically by default when the App launches), it will power on the device, if not already. Within the App, pressing on the top bar that displays the probe name or serial, as well as the loaded application, will reveal the power off button. Press this button to power down the scanner and de-select it from the App.

Audible indicators of the Clarius scanner emits:

Sounds	Meaning
2 quick beeps	Scanner components are ready
3 quick beeps	Bluetooth is ready
2 tone-increasing pitches	Power on
2 tone-decreasing pitches	Power off
1 beep every few seconds	Battery is critically low
Ringing	Find my scanner

Automatic Shut Off

The scanner has the functionality to automatically shut off after various timeout scenarios. The default timeouts are set as below:

1. Powered on, but no App connection:
   • Turns off in 5 minutes
2. Powered on, connected, but no imaging performed, or imaging frozen:
   • Turns off in 15 minutes
   • Reprogrammed through the Keep Awake setting of the App

Automatic Freezing

The scanner can also automatically freeze imaging after certain conditions are met. These methods will help save large amounts of battery power as the device consumes the most while imaging. 

1. Contact Detection
   • After 3 seconds of no patient contact detected, lower frame rate is engaged
     • Reprogrammed through the Contact Detection setting
   • After 30 seconds of low frame rate mode, scanner will stop imaging
     • Reprogrammed through the Auto Freeze setting
2. Motion Sensor
   • After a period, the scanner will stop imaging if no physical motion is detected (default setting is disabled)
   • Reprogrammed through the Stationary Timeout setting, with allowable values of 10 - 120 seconds

Eco Mode 

Eco Mode can be used to reduce battery consumption as well as reduce the heat produced while scanning. This function moderately lowers frame rate and tunes the electronics to function in a lower power mode of operation. To engage Eco Mode:

1. On the imaging screen, open the modes menu .
2. Press the Eco Mode icon .
