removing the single Phillips screw on the front of the module to
access the battery inside. Reinstall the alarm module.

• Slowly raise the sash until the bottom of the sash aligns with the sash
indicator decal located on the left side of the work area.
• Turn on the fluorescent light and cabinet blower if the Smart-Start
features have not been activated.

reading.

gloves. Use protective eyewear. Wear a protective mask if
appropriate.
