The lamp housing gets extremely hot during operation.

To avoid eye injury from ultraviolet radiation exposure,
• power-off the detector before changing the lamp;
• wear eye protection that filters ultraviolet light;
• keep the lamp in the housing during operation.
Warning:
The lamp and lamp housing can be hot. Wait 30 minutes after powering off
the detector for these components to cool before touching them.

cushion an old lamp by containing it in the packaging of its replacement before you
dispose of it.
