The Backup Time
An important safety feature of Daavlin’s dosimetry system is the use of a backup safety time. While
the dose is entered in Joules or milliJoules, a backup time must also be entered as a safety check.
The treatment will stop when the dose has been delivered, OR, when the backup time has elapsed,
whichever comes first. At the end of the treatment, the dose delivered and the time elapsed are
alternately displayed so that you will know which limit ended the treatment.
When preparing for a treatment, the back-up time is entered first. To determine an appropriate back-
up time, it is necessary to know the power output of the device. Those instructions follow:
If you have a 1 Series and will be treating your hands, elbows or other areas of the body that can
be placed directly on the plastic guard of the device, use the instructions directly following. If
you will be treating larger areas of your body where it is impossible to have the skin in direct
contact with the plastic lamp guard, then, be sure to read the additional instructions on pages 19
and 20.
Power Output Measurement
Power output values of the device as measured at the factory are shown on the
Power Output
Certificate
included in your manual.
Note:
It is not necessary to take a power output reading before
each treatment. We suggest once every couple of weeks or earlier if the backup time ends your
treatment before the full dose has been delivered.
