MAINTENANCE
Lens Protector
The lens barrel has threads on the outside for mounting a commercially available lens protector (φ 62mm for LT260/LT220 and φ 72mm for LT240) to protect the lens from dirt, dust, scratches and damage. Note that both a lens protector and the supplied lens cap cannot be used at the same time.
CAUTION: Use only transparent lens protectors designed for lens protec- tion. Use of filters for light reduction and special effects, such as ND (Neu- tral Density) filters and color filters, can absorb heat, resulting in damage to the filter and the projector.
