<p class="yiv8440840048msonormal"> <o:p></o:p></p>
<p class="yiv8440840048msonormal">I have 3 quick questions about your policy for changing the UV-lamp on the MA6 (Karl Suss) mask aligners. <o:p></o:p></p>
<p class="yiv8440840048msonormal">1. do you turn off the UV - power supply during nights and weekends? or just leave it on?<o:p></o:p></p>
<p class="yiv8440840048msonormal">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?<o:p></o:p></p>
<p class="yiv8440840048msonormal">3. how often do you change the lamp?<o:p></o:p></p>
