Attaching the Lamp Housing

1. Fit the lamp housing @ all the way into the lamp housing mount on the

rear of the microscope arm.

Attach the lamp housing so that the heat radiating fins ² face up-

ward. To prevent a fire hazard, reserve ample spaces above, below

and on the rear of the lamp housing.

2. After fitting the lamp housing @, tighten the two clamping screws ³

using the Allen screwdriver provided with the microscope.

# Do not tighten the screws too much, as this may deform the lamp

housing mount.

3. For the connection of the connector | of the lamp housing, see

Connecting the Module Connection Cables" (page 21).

Attaching the Mercury Burner

}For the xenon burner, attach the burner, reset the hour counter and con-

nect the cables as described in the manual provided with the light source

in use.

1. Loosen the socket clamping screw @ using the Allen screwdriver.

2. Hold the upper section of the lamp housing and pull it upward to remove

the socket section.

# To prevent malfunction, do not hold the lamp housing by the center-

ing knobs ².

3. Place the socket section upside down as shown in Fig. 17.

}The lamp housing is equipped with the holder for transportation in the

factory shipment condition or with an old burner when the burner is

replaced. Remove the holder or old burner by loosening the two burner

holding screws ³.

4. Attach the + (positive) pole of a specified mercury burner | to the fixed

mount on the upper side, then the - (negative) pole to the mount on the

lower side.

# Be sure to use the USH-103OL (USHIO) or the HBO103W/2 (OSRAM)

mercury burner.

Be careful and avoid leaving fingerprints or contaminants on the

mercury burner. Otherwise, there is a danger of explosion due to

distortion of glass caused by the stains. If the burner is contami-

nated, clean it by wiping gently with gauze slightly moistened with

absolute alcohol.

5. Attach the socket section with burner to the original position and tighten

the socket clamping screw @.

# Align the external edges of the lamp housing with those on the

socket section, and push the lamp housing straight downward.

Attach the lamp housing so that the heat radiating fins face upward.

To prevent a fire hazard, reserve ample spaces above, below and on

the rear of the lamp housing.

Do not light the mercury burner while it is not mounted on the micro-

scope because the UV rays in its light are harmful to your eyes. Also,

the UV rays in the light of the mercury burner may damage the speci-

men if this is sensitive to UV rays.
