9. Cautions for use
 The TEL1050 rangefinder employs an eye-safe laser. Nevertheless, do not switch the
unit while aiming at a human eye or while looking into the lens.
 Do not aim at the sun or strong light with the product so that the photosensitive
elements are not damaged.
 Keep the rangefinder out of reach of children.
 Do not disassemble the product.
 Do not use any power source other than a 3-V CR2 Lithium battery.
 Make sure the battery polarity is correct.
 Remove the battery from the product if you are not using it for an extended period.
 The device can only be used outdoors
10. Maintenance
Lenses
 Do not wipe dust or sand from the lens, but rather blow it off or remove it using a soft
lens brush.
 Fingerprints may affect the lens surfaces after a time. The easiest way to clean lens
surfaces is to breathe on them and rub them using a clean optic-cleaning cloth.
 Use of a coarse cloth or unnecessary rubbing may scratch the lens surface and
eventually cause permanent damage.
 Do not use a velvet cloth or ordinary tissue, as it may scratch the lens surface.
 Once a cloth has been used for cleaning the body of the product, it should not be used
again for the lens surface.
 For a more thorough cleaning, photographic lens tissue may be used.
