Caring for the Camera and Battery: Cautions

Cautions: Using the Camera

Do Not Drop
Do not drop the camera or lens or subject them to blows. The product may malfunction if subjected to strong shocks or vibration.
Keep Dry
Keep the camera dry. Rusting of the internal mechanism caused by water inside the camera can not only be expensive to repair but can in fact cause irreparable damage.
Avoid Sudden Changes in Temperature
Taking the camera from a warm to a cold environment or vice versa may cause damaging condensation inside and outside the camera. Place the camera in a sealed bag or plastic case before taking it across a temperature boundary. The camera can be taken from the bag or case once it has had time to adjust to the new temperature.
Keep Away from Strong Magnetic Fields
Static charges or the magnetic fields produced by equipment such as radio transmitters could interfere with the monitor, corrupt data stored on the memory card, or affect the product’s internal circuitry.
Keep Credit Cards and Other Such Magnetic Storage Devices Away from the Camera and Lens
Data stored on the device could be corrupted.
Do Not Leave the Lens Pointed at the Sun
Do not leave the lens pointed at the sun or other bright light source. Intense light may damage the image sensor or cause fading or “burn in”. Photographs taken with the camera may exhibit a white blur effect.
Lasers and Other Bright Light Sources
Do not direct lasers or other extremely bright light sources toward the lens, as this could damage the camera’s image sensor.
When cleaning the camera body, use a blower to gently remove dust and lint, then wipe gently with a soft, dry cloth. After using the camera at the beach or seaside, wipe off any sand or salt using a cloth lightly dampened in fresh water and then dry the camera thoroughly. In rare instances, static electricity may cause the LCD displays to light up or go dark; this does not indicate a malfunction. The display will soon return to normal.
Cleaning the Lens and Viewfinder
These glass elements are easily damaged: remove dust and lint with a blower. If using an aerosol blower, keep the can vertical to prevent the discharge of liquid that could damage glass elements. To remove fingerprints and other stains from the lens, apply a small amount of lens cleaner to a soft cloth and wipe the lens carefully.
Do Not Touch the Image Sensor

Under no circumstances should you exert pressure on the image sensor, poke it with cleaning tools, or subject it to powerful air currents from a blower. These actions could scratch or otherwise damage the sensor.

Cleaning the Image Sensor
For information on cleaning the image sensor, see “Image Sensor Cleaning” (0Image Sensor Cleaning) and “Manual Cleaning” (0Manual Cleaning).
Do Not Touch the Sensor Shield

If [Sensor shield closes] is selected for [Sensor shield behavior at power off] in the setup menu, the sensor shield in front of the image sensor will close when the camera turns off. Never pierce or apply pressure to the sensor shield. Failure to observe this precaution could scratch or otherwise damage the shield.

The Lens Contacts
Keep the lens contacts clean. Avoid touching them with your fingers.
Store in a Well-Ventilated Area
To prevent mold or mildew, store the camera in a dry, well-ventilated area. Do not store the camera with naphtha or camphor moth balls, next to equipment that produces strong electromagnetic fields, or where it will be exposed to extremely high temperatures, for example near a heater or in an enclosed vehicle on a hot day. Failure to observe these precautions could result in product malfunction.
Long-Term Storage
To prevent damage caused for example by leaking battery fluid, remove the battery if the product will not be used for an extended period. Store the camera in a plastic bag containing a desiccant. Do not, however, store the leather camera case in a plastic bag, as this may cause the material to deteriorate. Store the battery in a cool, dry place. Note that desiccant gradually loses its capacity to absorb moisture and should be replaced at regular intervals. To prevent mold or mildew, take the camera out of storage at least once a month, insert the battery, and release the shutter a few times.
Turn the Product Off Before Removing or Disconnecting the Power Source
Removing or disconnecting the power source while the camera is on could damage the product. Particular care should be taken not to remove or disconnect the power source while pictures are being recorded or deleted.
  • The monitor and viewfinder are constructed with extremely high precision; at least 99.99% of pixels are effective, with no more than 0.01% being missing or defective. Hence while these displays may contain pixels that are always lit (white, red, blue, or green) or always off (black), this is not a malfunction. Pictures recorded with the device are unaffected. Your understanding is requested.
  • Pictures in the monitor may be difficult to see in a bright light.
  • Do not apply pressure to the monitor. It could malfunction or suffer damage. Dust or lint can be removed with a blower. Stains can be removed by wiping the monitor lightly with a soft cloth or chamois leather. Should the monitor break, care should be taken to avoid injury from broken glass. Be careful that liquid crystal from the monitor does not touch the skin or enter the eyes or mouth.
  • Should you experience any of the following symptoms while framing shots in the viewfinder, discontinue use until your condition improves:

    • nausea, eye pain, eye fatigue,
    • dizziness, headache, stiffness in your neck or shoulders,
    • queasiness or loss of hand-eye coordination, or
    • motion sickness.
  • The display may rapidly flicker on and off during burst photography. Watching the flickering display could cause you to feel unwell. Discontinue use until your condition improves.
Bright Lights and Back-Lit Subjects
Noise in the form of lines may in rare cases appear in pictures that include bright lights or back-lit subjects.
Camera Shooting and Playback Displays
When [HLG] is selected for tone mode, the shooting and playback displays in the camera monitor and viewfinder may include “noise” in the form of randomly-spaced bright pixels, fog, or lines or may fail to accurately reproduce highlights and highly-saturated colors. In addition, abrupt tone discontinuities may be visible in the camera monitor or viewfinder when photos are displayed full-frame, although the photos themselves are unaffected. For accurate tone reproduction, use monitors, computers, operating systems, applications, and other equipment compatible with HLG.

Cautions: Using Batteries

Precautions for Use
  • If improperly handled, batteries may rupture or leak, causing the product to corrode. Observe the following precautions when handling batteries:

    • Turn the product off before replacing the battery.
    • Batteries may be hot after extended use.
    • Keep the battery terminals clean.
    • Use only batteries approved for use in this equipment.
    • Do not short or disassemble batteries or expose them to flame or excessive heat.
    • Replace the terminal cover when the battery is not inserted in the camera or charger.
  • If the battery is hot, for example immediately after use, wait for it to cool before charging. Attempting to charge the battery while its internal temperature is elevated will impair battery performance, and the battery may not charge or charge only partially.
  • If the battery will not be used for some time, remove it from the camera and store it in a cool, dry location with an ambient temperature of 15 °C to 25 °C (59 °F to 77 °F). Avoid hot or extremely cold locations.
  • Batteries in long-term storage should be charged to about 50% at least once a year. Do not charge the battery to 100% before returning it to storage. A fully-exhausted battery will charge to around 50% in about half the time needed to charge it to 100%.
  • Remove the battery from the camera or charger when not in use. The camera and charger draw minute amounts of charge even when off and could draw the battery down to the point that it will no longer function.
  • Do not use the battery at ambient temperatures below −10 °C (14 °F) or above 40 °C (104 °F). Failure to observe this precaution could damage the battery or impair its performance. Charge the battery indoors at ambient temperatures of 5 °C–35 °C (41 °F–95 °F). The battery will not charge if its temperature is below 0 °C (32 °F) or above 60 °C (140 °F).
  • Capacity may be reduced and charging times increase at battery temperatures from 0 °C (32 °F) to 15 °C (59 °F) and from 45 °C (113 °F) to 60 °C (140 °F).
  • Batteries in general exhibit a drop in capacity at low ambient temperatures. Even fresh batteries charged at temperatures under about 5 °C (41 °F) may show a temporary increase from “0” to “1” in the setup menu [Battery info] age display, but the display will return to normal once the battery has been recharged at a temperature of about 20 °C (68 °F) or higher.
  • Battery capacity drops at low temperatures. The change in capacity with temperature is reflected in the camera battery-level display. As a result, the battery display may show a drop in capacity as the temperature drops, even if the battery is fully charged.
  • Batteries may be hot after use. Observe due caution when removing batteries from the camera.
Charge Batteries Before Use
Charge the battery before use. The supplied battery is not fully charged at shipment.
Ready Spare Batteries
Before taking photographs, ready a spare battery and keep it fully charged. Depending on your location, it may be difficult to purchase replacement batteries on short notice.
Have Fully-Charged Spare Batteries Ready on Cold Days
Partially-charged batteries may not function on cold days. In cold weather, charge one battery before use and keep another in a warm place, ready to be exchanged as necessary. Once warmed, cold batteries may recover some of their charge.
Battery Level
  • Turning the camera on or off repeatedly when the battery is fully discharged will shorten battery life. Batteries that have been fully discharged must be charged before use.
  • A marked drop in the time a fully charged battery retains its charge when used at room temperature indicates that it requires replacement. Purchase a new rechargeable battery.
Do Not Attempt to Charge Fully-Charged Batteries
Continuing to charge the battery after it is fully charged can impair battery performance.
Recycling Used Batteries
Recycle rechargeable batteries in accord with local regulations, being sure to first insulate the terminals with tape.

Cautions: Using the Charger

  • Do not move the charger or touch the battery during charging; failure to observe this precaution could in very rare instances result in the charger showing that charging is complete when the battery is only partially charged. Remove and reinsert the battery to begin charging again.
  • Do not short the charger terminals. Failure to observe this precaution could result in overheating and damage to the charger.
  • Unplug the charger when it is not in use.
  • Use the MH-25a with compatible batteries only.
  • Do not use chargers with damage that leaves the interior exposed or that produce unusual sounds when used.
