Precautions for use  Handle carefully. Do not drop the product, or subject it to strong shock or vibration. Do not carry or move the product by the fader lever. This is important to prevent malfunctioning or accidents.  Use the product in an ambient temperature of 0 °C to 40 °C (32 °F to 104 °F). Avoid using the product at a cold place below 0 °C (32 °F) or at a hot place above 40 °C (104 °F) because extremely low or high temperature will adversely affect the parts inside.  Power off before connecting or disconnecting cables. Before plugging or unplugging the cables, be sure to switch power off.  Avoid humidity and dust. Avoid using the product at a humid, dusty place because much humidity and dust will cause damage to the parts inside.  Maintenance Turn off the unit's power and wipe the product using a dry cloth. To remove stubborn dirt, dip a cloth into a diluted solution of kitchen detergent (neutral), wring it out well, and wipe the product gently. Then, after wiping the product with a moist cloth, wipe it again with a dry cloth. Caution • Avoid using benzine, paint thinners and other volatile fluids. • If a chemical cleaning cloth is to be used, carefully read through the precautions for its use.  Built-in display (LCD monitor) Leaving the built-in display on with the same image over a long period of time may result in temporary afterimage (burn-in). Such afterimages are usually resolved when ordinary moving images are displayed for a while. The liquid crystal parts are highly precise with 99.99% of the pixels effective. This leaves less than 0.01% of pixels that may not light or may remain on all the time. These phenomena are normal and will have no effect on the images you shoot. Condensation may form if you use the unit where temperatures fluctuate. Wipe dry with a soft, dry cloth. When the unit has completely cooled down, the display on the LCD monitor appears slightly darker than usual immediately after the power has been turned on. Once the internal temperature of the unit rises, the display returns to the normal brightness.  When the product is to be discarded When the product is to be discarded at the end of its service life, ask a specialized contractor to dispose of it properly in order to protect the environment.  Concerning the consumable parts Cooling fan: This is a consumable part. As a general rule, replace it every 5 years or so (when the unit has been operated for 15 hours a day). The period when the consumable parts need to be replaced will differ depending on the operating conditions. When the time comes to replace one of these parts, be absolutely sure to ask your dealer to do the job.  Precaution to be observed during production This product's image switching and image effect functions can be used to produce images which flicker rapidly or images which change rapidly. However, bear in mind when using these functions in production that the kinds of images produced may have an adverse effect on the viewer's physical well-being. 12
