====== Equipment Handling and Maintain Guide ======

Note: DSLR camera is not compact camera, as when you interchange lens, dust can come in, so

  * keep you DSLR equipment in a safe, dry, good air flow environment, as in wet environment, Fungus can grow into the equipment, (which is bad)
  * when interchange lens, make sure camera open mount is facing down, so no dust drop in,
    * blow away dust when lens is mount up while mount part face up.
    * then mount it.
  * camera bag should be clean and soft and safe.
  * get a dry box if possible, but as long as you use it every day, shine them under the sun, they will be healthy and fresh

====== Dry Cabinet ======

  * for the digital dry cabinet, for manual humidity level setting, 
    * Green Zone = 55-60% setting
    * Blue Zone = 40-55% setting
    * Red Zone = 35-45% setting

====== My Fighting of the Lens Maintaining ======

  * I have met Fungus with my first lens, it is in the corner, but as I use this lens most time, it didn't grow, and my APS-C doesn't not see this full frame lens corner;
    * the technical term for lens opener is: "Spanner Wrench" ([[http://item.taobao.com/item.htm?id=10279615055&ad_id=&am_id=&cm_id=&pm_id=|双头工（井）字扳手]])

====== Digital Camera Problem and Fix ======

  * Problem: Camera reset time every time when changing battery
    * Fix 1: try using a different brand memory card (example, a kingston, sandisk, transcend, etc) or try checking if reset problem still existing when there is no card while changing battery
    * Fix 2: if fix 1 failed, try using another battery
    * Fix 3: if fix 2 failed, try re-install firmware
    * Fix 4: leaving a charged battery in camera for a few days to recharge internal clock battery
    * Fix 5: clean the battery's contact area (with alcohol)
    * conclucion if all failed: those capacitors in internal cameras have a limited cycle life, leaving camera without battery for too many times, like those people prefer to keep battery out of camera when not using, may have got this issue.
    * last solution, send to service center to fix it.
