Keeping your XT Camera clean
Your XT Camera System generally needs very little maintenance. However, as
this is a professional tool it should be treated with proper care and caution.
Always perform test shots before a photographic session if the camera, for
any reason, has not been used for a long period of time.
Note: If the XT Camera is suddenly taken from a cold to a warm place,
condensation may form on internal parts. In this case, do not use the camera.
Instead remove the lens, memory cards and battery from the IQ4. Then wait
until the condensation has evaporated before using the camera again.
XT Camera Body
Keep the electronic contacts and mount of the XT Camera Body clean and
free of dust with a dry microfiber cloth, but do not re-use the cloth on the lens’
surface. If the camera has been exposed to salty air, wipe it clean with a well-
wrung wet cloth.
To clean the screen on the IQ4, wipe it using a microfiber cleaning or soft
damped cloth. This will remove dust, dirt and fingerprints from the screen
without scratching or streaking.
WARNING: Do not use any solvents or liquid-based cleaners as these substanc-
es may damage the lcd screen coating. Never touch the electronic contacts
with your fingers as this can lead to corroding of the contacts and camera
system malfunction.
Lens
If there is any dust on the surface of optics, first try to remove it with a rocket
air blower. Never use compressed air unless the product is made specifically
for photographic equipment, since the propellant can leave residue on the
glass surface that can be very dicult to remove.
If there are smudges on the lens surface, use the dry lens cloth that was
supplied with the lens. Make sure to remove as much debris as possible with
an air blower first, so you do not end up grinding the debris into the glass. It
might be necessary to moisten the lens cloth with a fluid lens cleaner. Then
use a circular motion to gently remove smudges from the lens surface,
working from the center outward. Dust and smudges on the rear element of
the lens will have the most impact on image quality so make sure to clean this
part regularly.
Please note the lens is not waterproof. If it becomes wet, it should immediately
be dried with a cloth. If the lens is exposed to salt spray, moisten the cloth and
carefully clean the lens.
System Maintenance
WARNING: Never touch the optics of the lens with your fingers. Do not use
chemicals on a lens tissue or cleaning cloth that are not specifically made for
lens cleaning. Facial tissue is not recommended, as some brands are abrasive
and others contain oils and lotions that can streak your lenses. Do not touch
the electronic contacts with your fingers.
