Improper use may result in battery explosion, cracking or leakage, which could result in fi re, injury and/or pollution of the surrounding environ- ment. - Page 21 CP-S335(C9SM)/CP-X340(C9X)/CP-X345(C9XM) 6-5 Air filter WARNING ● Before caring, make sure the power switch is off and the power cable is not plugged in, and then allow the projector to cool suffi ciently. The care in a high temperature state of the projector could cause a burn and/ or malfunction to the projector.
- Page 22 CP-S335(C9SM)/CP-X340(C9X)/CP-X345(C9XM) 6-6 Lamp WARNING HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE ● The projector uses a high-pressure mercury glass lamp. The lamp can break with a loud bang, or burn out, if jolted or scratched, handled while hot, or worn over time. Note that each lamp has a different life- time, and some may burst or burn out soon after you start using them.
- Page 23 CP-S335(C9SM)/CP-X340(C9X)/CP-X345(C9XM) Replacing the Lamp When the indicators or a message prompts you to replace the lamp, replace the lamp as soon as possible. 1. Turn the projector off, and unplug the power cord. Allow the lamp to cool for at least 45 minutes.
- Page 24 CP-S335(C9SM)/CP-X340(C9X)/CP-X345(C9XM) 6-7 Other care WARNING Before caring, make sure the power switch is off and the power cable is not plugged in, and then allow the projector to cool suffi ciently. The care in a high temperature state of the projector could cause a burn and/ or malfunction to the projector.
- Page 25 CP-S335(C9SM)/CP-X340(C9X)/CP-X345(C9XM) 6-8 Notice of AUTO adjustment Use of AUTO adjustment with the image through RGB input optimizes V_POSI, H_POSI, H_SIZE and H_PHASE automatically. In case that projected image has dark tone around its peripheral, AUTO operation sometimes makes artifacts in the image, shifts capture area and so on. Those failures are caused by period of image data is not exactly distinguished to period of blanking on signal processing.
