Note: For your convenience, and as an alternative to the UVB backup 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.
17.3 Setting up a Treatment
You will first enter a backup time (steps 1 – 6). Based on the example above the back-up time
will be 00:30.
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 will be
0007.
3. Once the key code is entered, the display should read 00:00.
4. Press the ▲ key until the first digit of the backup time is displayed (“3” in this case).
5. Press the ◄ key to move the “3” one space to the left, display should now read 00:30.
6. Press ENTER to lock in your back up time.
Now you will enter the actual dose. Continuing our example from above the dose will be 280
milliJoules. Therefore, the first digit will be the number 2.
1. Press the MODE key to switch to dose mode. The display should now read 0000.
2. Press the ▲ key until the number “2” is displayed.
3. Press the ◄ key to move the “2” one space to the left.
4. Press the ▲ key until the number “8” is displayed.
5. Press the ◄ key to move the “8” one space to the left and repeat until all desired digits
are shown on the display. In this example the last digit is a zero, so once you have moved
the “8” into position, the “0” already shows and you can move on to step 6.
6. When the desired dose is displayed, press ENTER to lock in your dose.
7. Put on your goggles and position yourself per the instructions.
8. Begin the treatment by again pressing ENTER
To repeat the same dose for another exposure, press the END key to clear the display. Then press
the MODE and POWER keys at the same time and release. This will automatically bring up the
last treatment administered. Press ENTER to start the treatment.
Note: The system beeps three times to signal the end of the treatment and then flashes the
delivered dose on the display alternating with the elapsed time. If the complete dose is not
delivered, meaning that the backup time was reached before the dose was fully delivered, this is
an indication that the backup times being entered are not long enough. Verify that the sensor is
clean, unobstructed and centered in the hole of the reflector. Then, re-take your power output
reading and adjust the back-up time. It is normal to have to increase back-up times due to aging
lamps and/or because of slow starting lamps, low room temperatures or low line voltage.
