OPERATING PROCEDURE Measuring Progressive Power Lenses

When the height of the processed lens is small and near portion is lacked, the ADD power cannot bemeasured with the usual auto read function.

For such lenses, measure the point which is nearest to thenear portion with the auto read function.

The measurement point is out of the near por-tion, so the measured data is not near power ofthe original uncut lens.

The measuring procedure is same as normal lenses, but note the following things.

• Be sure to move the lenses in the vertical direction when the indicator for near portion ( )is not displayed on the right and left sides.Otherwise, the ADD power may be underestimated.

• Align the nosepiece so that more than half of it is covered with a lens.When the nosepiece is widely out of the lens, a measurement error occurs.

• The lack amount of the ADD power cannot be judged. Consider the additional poweracquired with this function as lower than actual.

When the height of the processed lens is sufficient

When the height of the processed lens is small

The near portion is lacked from a lens shape.

determined by an electromagnetic site survey,a should be less than the compliance level in

each frequency range.b Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobileradios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should beconsidered. If the measured field strength in the location in which the LM-600/LM-600P/LM-600PD is used exceedsthe applicable RF compliance level above, the LM-600/LM-600P/LM-600PD should be observed to verify normaloperation. If abnormal performance is observed, additional measures may be necessary, such as reorienting orrelocating the LM-600/LM-600P/LM-600PD.

b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
