Check for straight and correct fit.• Connect the 3-pin lamp plug (Fig. 3-29/6) to the respective socket on the back of the external powersupply unit (suited for two lamps) (Fig. 3-29/5): plug the TL illuminator into the lower TL socket, plugthe RL illuminator into the upper RL socket.• Connect the cable (Fig. 3-29/4) for illumination intensity control (see section 3.3.2).NOTEIf this cable is connected to the stand, the illumination intensity of the HAL 100 in use can bevaried by rotating the Intensity/LM knob (Fig. 2-2/6).If this cable is not connected to the stand, the illumination intensity of the HAL 100 in use canbe varied by rotating the adjusting wheel of the external power supply unit.To switch between the illuminators for reflected and for transmitted light, flip the toggleswitch of the power supply unit to TL for transmitted light or to RL for reflected light (seesection 3.3).Fig. 3-29 Mounting the HAL 100
