1. Make sure that the light intensity control knob @ is in the MIN (minimum
intensity) position and set the main switch ² to “ I ” (ON). (The POWER

}With the TH4, the position (approx. 9 V) marked indicates the position
where the daylight illumination suitable for photomicrography is obtained
when the 45LBD filter is engaged in the light path.
The position marked of the IX71 and TH4-HS also has the identical
function.
With the TL4, the position marked is not provided and even
the maximum light intensity (6 V) may sometimes be unsuitable
for photomicrography.
