<p class="yiv0695126812x_MsoNormal">HI Everyone,<u></u><u></u></p>
<p class="yiv0695126812x_MsoNormal"><u></u> <u></u></p>
<p class="yiv0695126812x_MsoNormal">I have 3 quick questions about your policy for changing the UV-lamp on the MA6 (Karl Suss) mask aligners. </p>
<p class="yiv0695126812x_MsoNormal">1. do you turn off the UV - power supply during nights and weekends? or just leave it on?</p>
<p class="yiv0695126812x_MsoNormal">2. do you change the UV lamp on a regular basis (after 1 month or so)? or you monitor it's power and have a lower limit before you decide to change it? or you just wait for it to fail and then change it?</p>
<p class="yiv0695126812x_MsoNormal">3. how often do you change the lamp?</p>
