1.1 General notes The packaging must be opened carefully to prevent any accessories inside from falling to the floor and breaking. In general, a microscope should always be handled with great care, as it is a sensitive precision instrument. Avoiding abrupt movements during operation or transport is therefore particularly important, especially to avoid endangering the optical components. Similarly, you should avoid dirt or fingerprints on the lens surfaces, because in most cases this reduces image clarity. If the performance of the microscope is to be maintained, it must never be disassembled. Components such as objective lenses and other optical components should therefore be left as they are found at the beginning of operation. 1.2 Notes on the electrical system Before connecting to a power supply network, it is important to ensure that the correct input voltage is used. The information to select the correct mains cable is located on the device, on the side of the product directly next to the connection socket. You must comply with this information. If you do not comply with these specifications, then fires or other damage to the device could occur. Likewise, the main switch should be turned off before connecting the mains cable. This prevents an electric shock from being triggered. If you use an extension cable, the mains cable used must be grounded. All handling of the units that involves contact with the electrics, such as changing lamps, may only be carried out when the power supply is disconnected.

high humidity. The suitable temperature range is 0 - 40° C and a relative humidity of 85 % should not be exceeded. The unit should always be on a firm, smooth and horizontal surface. When the microscope is not being used, you should cover it with the enclosed dust protective cover. Dust or dirt inside the optics of a microscope can in many cases cause irreversible malfunctions or damage. The best way to store accessories which consist of optical elements, such as, for example, additional objectives, is in a dry box with desiccant.

In any case, the unit must be kept clean and regularly cleaned of dust. Before wiping down the unit when wet, make sure that the power is switched off. Glass components should preferably be wiped lightly with a lint-free cloth if contaminated. To wipe off oil stains or fingerprints from lens surfaces, the lint-free cloth is moistened with a mixture of ether and alcohol (mixing ratio 70 / 30) and then used for cleaning. Ether and alcohol must always be handled with care as they are highly flammable substances. It is therefore essential to keep them away from naked flames and electrical appliances that are switched on and off, and to use them only in well- ventilated rooms. However, organic solutions of this type should not be used to clean other components of the unit. This could result in changes to the paintwork. It is sufficient to use a neutral cleaning agent for this purpose. Other cleaning agents for the optical components include:  Special cleaner for optical lenses  Special optical cleaning cloths  Bellows  Brush If handled correctly and checked regularly, the microscope will function smoothly for many years. Should a repair still be necessary, contact your KERN dealer or our Technical Service.
