To determine a “time equivalent”, consult the laminated Time Chart that is provided and find the power
output on the top row (horizontal axis). The numbers in the left most column (vertical axis) represent a
range of potential treatment doses. Find the dose then trace that row to the right until it intersects with
the column corresponding to the factory power output of the device. The time equivalent is shown where
the two lines intersect. For example, if the factory power output is 8.0 mW/cm
2
and the dose to be
delivered is 2 Joules, then the appropriate treatment time will be 04:10. A partial time chart illustrating
this is shown on the following page.
Note:
For your convenience, and as an alternative to the UV time chart, the latest version of our free
iPhone and Android application “Phototherapy Math” is available for download at the iTunes app store
and Android market. It quickly calculates treatment times, backup safety times, and makes the
calculation of dose and time increases simple. If using a PC, visit www.phototherapymath.com for a web
based calculator and additional information.

The UVA and UVA-1 Time Chart (not shown here) is configured the same as the UVB Time Chart. The doses
are listed in Joules and the energy output levels and times are different than the UVB output levels. Each
chart is clearly marked.

Setting Up a Treatment Time
To administer a treatment you must enter your desired treatment time. Based on the example above the
treatment time will be 4:10.
1.
Press any key to awaken the unit. The word “CODE” will appear.
2.
Enter in your key code. Unless you have changed it, the factory preset key code is 0007.
3.
Once the key code has been entered, the display should read 00:00.
4.
Press the
▲
key until the first digit of your desired time is displayed. If the treatment time is one
minute and ten seconds (04
:10), the first digit will be a “
4
”.
5.
Press the
◄
key
to move the “
4
” one space to the left. The display should read 00:
40.
6.
Press the
▲
key until the next desired number is displayed (“1” in this case). The display should
read 00:41.
7.
Press the
◄
key
to move the “
4
” one space to the left.
The display will now read 04:10.
8.
When the desired time is displayed (in this case 04:10) press the ENTER key to lock in your
treatment time.
Put on your goggles and position yourself per the instructions.
