MAINTENANCE Lens Protector The lens barrel has threads on the outside for mounting a commercially available lens protector (φ 62mm for LT260K and φ 72mm for LT240K) 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 protection. Use of filters for light reduction and special effects, such as ND (Neutral Density) filters and color filters, can absorb heat, resulting in damage to the filter and the projector. E-125
