Nikon D2Xs manual 257, Cleaning the Low-Pass Filter

6 Holding the camera so that light falls on the low-pass filter, examine the filter for dust or lint. If there are foreign objects on the filter, the filter requires cleaning. See the following section.

7 Turn the camera off. The mirror will return to the down position and the shutter curtain will close. Replace the lens or body cap and disconnect the AC adapter.

Cleaning the Low-Pass Filter

The low-pass filter is extremely delicate and easily damaged. Nikon recom- mends that filter be cleaned only by Nikon-authorized service personnel. Should you choose to clean the filter yourself, follow the steps below.

1 Raise the mirror as described in steps 1–5 on the preceding page. Do not remove or disconnect the power source until cleaning is complete.

2 Remove dust and lint from the filter with a blower. Do not use a blower-brush, as the bristles could damage the filter. Dirt that can not be removed with a blower can only be re- moved by Nikon-authorized service personnel. Under no circumstances should you touch or wipe the filter.

3 Turn the camera off. The mirror will return to the down position and the shutter curtain will close. Replace the lens or body cap and disconnect the AC adapter.

Use a Reliable Power Source

The camera shutter curtain is delicate and easily damaged. If the camera powers off while the mirror is raised, the shutter curtain will close automatically. Observe the fol- lowing precautions to prevent damage to the curtain:

•Use a fully-charged battery or an EH-6 AC adapter (available separately) for pro- longed inspection or cleaning of the low-pass filter.

•Do not turn the camera off or remove or disconnect the power source while the mir- ror is raised.

•If the battery runs low while the mirror is raised, a beep will sound and the self-timer lamp will blink to warn that the shutter curtain will close and the mirror will lower in about two minutes. End cleaning or inspection immediately.
