Purchase a new light-source lamps (Part No. : BHL5003-SU) from the authorized dealer where you purchased the

CAUTIONS
• If the projector is set up in a constricted place which is unsuitable for work, and if you perform replacement work there, this
could cause injury. Move the projector to a place large enough for work, and then replace the light-source lamp.
• Use a genuine product for the light-source lamp. If you use other than a genuine product, this could cause a malfunction.
Also, never use an old light-source lamp. This could cause marked degradation in performance or explode, possibly causing
the projector to malfunction or broken pieces to injure you.
• Do not replace the light-source lamp immediately after the projector has been used. The temperature of the light-source
lamp is still high and could cause a burn. Allow a cooling period of one hour or more before performing replacement.
• Before starting light-source lamp replacement work, turn off the MAIN POWER switch, and disconnect the power cord from
the wall outlet. If you perform the replacement work with the power cord connected, this could cause injury or electric shock.
• The light-source lamp used in this projector is a high pressure mercury lamp. Be careful when disposing of the light-source
lamp. If anything is unclear, please consult your dealer.
