The ‘CONTROL’ menu contains 4 sub-menus ‘RANGE’, ‘GAIN’, ‘POWER’ and ‘FREQUENCy’. Press 
soft key 2 to cycle through the sub-menus. Then use the arrow keys at soft keys 3 and 4 to adjust 
the settings.

A: RAnGE
When ‘RANGE’ is displayed above soft key 2, the arrow keys can be used to adjust the range to the 
following values: 3 cm, 6 cm, 9 cm, 12 cm, 16 cm, 19 cm, 22 cm, 25 cm, 28 cm and 32 cm. 

As the range is increased the probe speed and ultrasound frame rate are reduced, allowing time for 
the ultrasound echoes to return from greater depths. 

Note: The range can also be adjusted via the tally controller. Pressing tally ‘1’ & ‘2’ simultaneously 
shifts the range up, pressing ‘3’ & ‘0’ simultaneously shifts the range down.

B: GAIn
When ‘GAIN’ is displayed above soft key 2, the arrow keys can be used to adjust the gain within the 
range 1-10. 

This is typically set to 6 so that the background noise is just visible, but can be used to alter echo levels 
as required. 

C: POwER
When ‘POWER’ is displayed above soft key 2, the arrow keys can be used to adjust the power within the 
range 1-10. 

This increases or decreases the penetration of ultrasound. Power should be set to 9 and only 
decreased when scanning in the lower ranges (below 12 cm). 

D: FREquEnCY
When ‘FREQUENCy’ is displayed above soft key 2, the arrow keys can be used to adjust the frequency 
to the following values: 2.5 MHz; 3.5 MHz; 5.0 MHz and 7.5 MHz. 

N.B. The default value for each of the above settings can be altered by the user, see 2.2.8
