• Do not store the instrument in the following locations.
- Environments exposed to high temperature, high humidity and large amounts of dust or particulate
- Locations exposed to direct sunlight or radiation
- Locations exposed to gas that includes halide
*1
Otherwise, the instrument may be damaged.
*1 The performance of some electrical parts may deteriorate due to the halide in insecticides,
pesticides and gaseous extinguishing agents, etc.
• Do not continue to use the instrument when it is wet with condensation.
In case of a sudden temperature change, such as entering a warm room from cold outside,
condensation may be caused inside the instrument. Using the instrument while it is wet with
condensation may cause malfunction. If condensation occurs, leave the instrument in the environment
where it will be used and allow the condensation to dry before using it.
• Do not insert the insertion tube into the inspection object which is in an environment that exceeds the
operating temperature range.
The continued use may damage or deteriorate the performance of the instrument.
• Do not use the instrument if the contaminants are attached to the outer surface of the instrument.
The instrument may be damaged or the performance may be deteriorated.
• Do not cover the main unit with a plastic bag or other objects.
The inside of the instrument may not be cooled down sufficiently, which may damage the instrument.
• Do not allow any liquids other than water, saltwater, machine oil or diesel oil to be attached to the
insertion tube.
Otherwise, the insertion tube may be damaged.
• Be sure to attach the O-ring to the insertion tube's distal end before using the optical adapter.
Water getting into the area where the insertion tube and optical adapter join might cause malfunction or
damage. Also note that an optical adapter by itself is not watertight.
• Never use the instrument while dirt or water is present in the optical adapter.
Water tightness between the optical adapter and the distal end may be lost, or the optical adapter or the
distal end may be damaged.
• Do not clean the optical adapter under running water.
Otherwise, the optical adapter might be damaged.
• Do not bend the insertion tube to a radius that is less than its minimum bend radius (20 mm for the
4-mm type, 30 mm for the 6-mm type and 6.2-mm type) whenever operating the angulation section.
• Note the following precautions when handling the battery cover and the connector cover.
- Do not open or close covers with your wet hands.
- Do not open or close covers in the area exposed to high humidity and/or dust.
- Close covers when storing the instrument and when the terminals are not in use.
• Note the following precautions when taking out the instrument from the carrying case.
- When taking out the scope unit or the main unit, do not hold it up with the insertion tube.
The instrument may be damaged.
• Note the following precautions when storing the instrument in the carrying case.
- Make sure that the distal end has cooled down sufficiently before storing it.
• Do not remove the battery or the AC adapter during operation.
Otherwise, the recorded data may be damaged.
• Do not remove the SDHC card or the USB flash drive while recording or replaying the image.
Otherwise, the recorded data or the image recording media may be damaged or lost.
• Do not repeat inserting or removing the SDHC card or the USB flash drive continuously.
Otherwise, the recorded data or the image recording media may be damaged or the SDHC card may
not work properly.
• Be careful for followings when using the extendable handle of the carrying case.
- Be careful you do not catch your hand when storing the handle inside the carrying case.
- Do not attempt to lift the carrying case by holding the extendable handle.
