D3 Lamp Exchange
The lamp compartment is left of the display and covered with a slotted cap on the upper side of the
housing. If the lamp is broken, it should be exchanged by Dr. Lange service staff, because w e
recommend a general instrument check-up after an operating period of 1-2 years. If you insist on
doing it yourself, proceed as follows:
R e m o v e p o w e r s u p p l y u n i t o r b a t t e r y!
Remove the grey cover of the bit-box. Loosen
the fixture of the bit-box by pushing the locking
clamp and put it apart. Unplug contact
from the lamp. Loosen the metal clamps at
the upper end one be one from their stay and
hinge them away. Take the lamp off and put
in a new one with the marking pointing to the
left.
Attention: Do not touch the glass bulb of
the lamp.
Hinge the metal clamps back to their places and
fix them to their stay. Connect the new lamp
with the plug-in contact and do the same
steps as for dismantling, but in reverse sense.
Only when the instrument is mounted
completely, turn it on and test it.
