CAUTION MARKS
y
Care must be taken not to stain and damage the caution marks applied to this instrument. Identify one caution mark applied on the side of the instrument and on the rear side.
y
The Printer Cover is attached with a metallic blade. Sufficient care must be taken not to touch the blade with yourself, or you may otherwise suffer from injuries.
y
The external output terminal is not insulated with an internal circuit of this instrument. Therefore, the internal circuit may be disordered depending on its connecting mode. Be sure that, if any external output terminal is used for this instrument, ask Tomey for appropriate advice.

y
The TL-2000B is composed of a built-in optical system, an electronic processing system, and a mechanical system.
y
Placing the spectacles or contact lenses on the nose piece initiates automatic measurement. The results are displayed on the LCD and the reading can be printed.

3. OPERATING PROCEDURES 3.1 Precautions for Operation
The external output terminal is not isolated for the internal electric circuits of this instrument. The internal circuits may, therefore, be disordered depending on their wiring mode. Be sure to consult with Tomey, if intending to use an external output terminal for this instrument.
y It is noted that the lens holder can only be used when marking the lens. When measuring a coated lens and if moving it as being held with the holding pressure, the coated surface of the lens may be damaged. y The protective glass provided under the nose piece should be cleaned with soft cloth from time to time. y The tip of the nose piece should always be cleaned. The tip stained with dust may damage the lens surface. y When cutting the printed paper with the cutter, first extend the paper over the blade and then pull it to cut. Cutting the paper without touch with the blade may cause to clog or damage the printer itself. y Always place the dust cover after using the instruments. y If the instrument is not used for an extended period, disconnect the power plug from the receptacle and place the dust cover.
