MAINTENANCE AND INSPECTION: Common
4Remove the burned-out lamp (with socket and terminal cord) from the lamp holder.
5Replace with a new lamp and socket by reversing Step 4 → 3.
6Replace the lamp house unit in its original position.
Insert the three guide pins of the lamp house unit into the guide hole on the instrument, to fix the
unit index in the position. Then return the lamp house unit to the A or B position.
Make sure that the new lamp lights up.
The new lamp can now be considered as the spare lamp.
The lamp is a consumable part. Contact your distributor or the Topcon offices stated on the
back cover to order the lamp. (Refer to "CONSUMABLE PARTS" on P.89~P.90.)
