3.8 Replacing/Charging the Battery 

3.8.1 Battery Energy Indication 

After switched on, the Doppler gives indication of battery energy. 

For  SONOTRAX Lite and SONOTRAX Vascular, the LED in the bottom left corner of the 

display panel lights up in green. When it flashes in orange, the battery power is low. 

For  SONOTRA Basic, SONOTRAX Basic A, SONOTRAX Pro, SONOTRAX II and 

SONOTRAX II Pro, there is a battery symbol in the bottom left corner of LCD. The panes in it 

indicate the battery electric energy. 

SONOTRA Basic               Other Models 

The panes disappear gradually with the energy consumption. When the energy is low, the empty 

battery symbol flashes and the Doppler gives sharp alarm sounds (NOTE: SONOTRAX Basic 

does not give alarm sound). Approximately five minutes later, the Doppler shuts down 

automatically. 

You should replace the batteries or charge the rechargeable batteries. 

3.8.2 Replacing Alkaline Batteries 

CAUTION 

Make sure the Doppler is shut down before charging the battery or opening the battery 

compartment.  

When the alkaline batteries are low in energy, they should be removed from the main unit, by 

using the procedures described in section 3.2 Installing/Replacing Battery. Dispose of them 

according to local regulations. 

New alkaline batteries with identical specifications are required. Install them to the Doppler as 

introduced in section 3.2.
