• All UVA and UVB combination units that feature our Integrated Dosimetry control
system will come equipped with separate controllers for UVA and UVB treatments. Be
sure to enter the desired UVA dose into the controller labeled UVA and the desired UVB
dose into the controller labeled UVB.
• All UVA and UVB combination units that feature our Digital Timer control system will
come equipped with one controller for both UVA and UVB treatments. There is a switch
in the center of your control panel that will allow you to toggle between UVA and UVB
operation.
Note: It is very important to make sure that the toggle switch is in the correct position for
your desired treatment. Always remember to push the switch up for UVA light and down
for UVB light.
• With all combination units the UVA lamps will be the first four lamps in the unit. The
UVB lamps will be the last four. Therefore, if you are using the UVA lamps, position
your hands or feet at the front of the device. If using the UVB lamps, position your hands
or feet in the back half of the unit.
23.4 How to Position the Patient
The hands, feet or elbows should be placed through the arched exposure ports in the front shield
and laid directly on the acrylic guard that covers the lamps. Intensity is highest towards the
horizontal center of the unit. Rings or other jewelry may cause scratching of the shield and
should therefore be removed.
Note: With all combination units the UVA lamps will be the first four lamps in the unit. The
UVB lamps will be the last four. Therefore, if you are using the UVA lamps, position your hands
or feet at the front of the device. If using the UVB lamps, position your hands or feet in the back
half of the unit.
23.5 M Series Lamp Removal and Replacement
Lamps may need to be replaced due to burnout or because their energy output has decreased to
the point that you may no longer be receiving an effective treatment.
DO NOT REPLACE LAMPS INDIVIDUALLY. ALL LAMPS SHOULD BE REPLACED
AT THE SAME TIME TO AVOID UNEVEN TREATMENTS OR ERYTHEMA.
PLEASE CONTACT THE DAAVLIN SERVICE DEPARTMENT PRIOR TO
REPLACING YOUR LAMPS TO OBTAIN IMPORTANT INFORMATION ON HOW
THE OUTPUT OF YOUR UNIT WILL BE AFFECTED BY THE CHANGE.
Because of differences between brands, replace lamps with the same brand as originally
installed.
1. Unplug the machine, disconnect the hood cord from the base, and remove the hood. Once
the hood is detached carefully set it aside.
2. Turning to the base, use a flat head screwdriver to remove the screw, located at the back
of the unit, which holds the acrylic shield in place.
3. Slide the acrylic shield forward to remove it from the base.
