Enter the first letter of desired diagnosis name and press the [ENTER] push button to enter the list of diagnoses. Use
the [ + ] and [ - ] arrows to move between diagnoses names and press the [ENTER] push button to select desired
diagnosis. After selecting desired diagnosis, preset therapy parameters will be displayed. Press the [ESC/STOP]
push button to return to previous menu.

2.5 Adjusting therapy parameters
When adjusting preset therapy parameters, use the [MENU] push button to enter patient files, diagnoses, or user
settings.
2.5.1 Density
When the density is adjusted, the instrument automatically recalculates therapy time and power parameters.
2.5.2 Irradiated Area
When using a divergent probe, use the following table for the probe distances from skin:
Irradiated area

]
Distance of probe from skin
[cm]
0.5 1.5
1 2
1.5 2.5
2 3
2.5 3.5
3 4
When using a divergent probe, depth of penetration changes according to the distance of the probe from skin and it
is necessary to deduct the desired depth of penetration from the displayed distance of probe.
When using a convergent probe, distance of the probe from the skin is not a crucial factor. The distance is not
measured because the beams are parallel.
2.5.3 Power
When the power is adjusted, the instrument automatically recalculates the duration of exposure. Power value could
be adjusted within range 20% to 100% of maximal probe output. Output power and the duration of therapy has an
inverse relationship. An increase in power output will result in a decrease in therapy duration. Density will remain the
same. The instrument calculates output power in tenths of mW, but the display only shows whole numbers. Maximum
and minimum power depends on the type of probe used, preset density and area.
