<p>Users can choose different lamp mode to extend the lamp&rsquo;s lifespan. When Power Saving setting is on and without any signal input, the projector will automatically switch to Eco Mode and SuperEco Mode</p>
<ul>
<li>Eco Mode:&nbsp;This projector automatically switches from Normal to Eco Mode whenever it has been left idle for 5 minutes.</li>
<li>SuperEco Mode:&nbsp;When the projector has not received an input signal for 20 minutes, projected images are dimmed to 70%, extending the lamp&rsquo;s lifespan to 15,000 hours on average</li>
</ul>
<p><strong>Automatic Sleep Timer</strong></p>
<p>Forgetting to shut off projectors is a common occurrence, especially in public spaces such as classrooms and meeting rooms. PA503S&rsquo;s sleep timer allows you to select a period of inactivity that will determine when the projector should put itself into sleep mode automatically.</p>
<p><strong>Auto Power Off</strong></p>
<p>When no signal has been detected, the projector will automatically power off to conserve energy and lamp life.</p>
