Once you know the power output, nine (9) milliwatts in the example above, consult the laminated
Backup Time Chart, a partial example of which is included below. The numbers in the top row of the
chart (horizontal axis) represent a range of power output values. Find the value that is closest to the
power output of your device.
The numbers in the column at the left (vertical axis) represent a range of treatment doses. Find your
dose then trace that row to the right until it intersects with the column corresponding to the current
power output of your device. The backup time is shown where the two lines intersect. The times are
rounded up to the nearest 10-second increment. On the partial time chart shown below, thirty (30)
seconds is the backup time at a power output of 9.0 mw and a dose of 280 mJ.
PARTIAL UVB TIME CHART

Power output
The UVA and Blue Light Backup Time Charts (not shown) are configured the same as the UVB
Backup 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.
Determining a 1 Series Backup Time when the device is positioned away from your body:
Since the 1 Series can be used in two ways, there are two power output values of importance. If you
are placing your hands, elbows or forearm (for example) directly on the plastic lamp guard, the energy
output there is higher. When you take a power output reading, this is the value that is shown on the
display. All of the above instructions apply.
However, if you are treating other, larger areas of the body where it is impractical to have your skin in
direct contact with the plastic guard, then place the device at a distance of eight (8) inches (20cm)
from the area to be treated. The power output there will be 1/3 the value at the plastic guard.
Therefore, if the measured output is 9 milliwatts, you would divide the power output by three. In the
above example, the “at a distance” power output would be 3 and your backup time would be one
minute and thirty seconds instead of thirty seconds.
Setting up a Treatment
(See additional instructions below for the 1 Series)
You will first enter a back up time (steps 1 – 4). Assume the back-up time to be 00:30
1. Press any key so that 00:00 is displayed.
2. Press
▲
until the first digit of the backup time is displayed (“3” in this case).
3. Press
◄
to move the “3” one space to the left.
4. Press ENTER to complete the backup procedure.
i. Now enter the actual dose. Assume 280 milliJoules. Therefore, the first digit is
a “2”. )
5. Press MODE to switch to dose mode.
