hood (18), the lamp is screwed

into

its

socket. Do

not

allow

the

opal lamp

to

burn needlessly. Expose only

with

the

light

switch

or a connected exposure

timer.

If

you already have

the

photographic paper upon

the

projection board

and

wish

to

match up

the

projected

picture

the paper

Instead

of

the opal lamp,

for

black-and-white photography you can

also use

the

DANOLI cold-light

unit

which

has a built-in

transformer.

With

its

diffusion

soft

type

lighting

it

is mainly suitable

for

work

with

hard negatives or

for

the

enlargement

of

pictures

where

absolute

sharpness is

not

desired. The DANOLI

unit

with

its

built-in

transformer

and orange

filter

is inserted

as

follows

into

the

enlarger head

(5):

remove

the

serial number plate (13)

after

having unscrewed

the

two

lateral screws. Then draw out

the

twin

condenser and

the

filter

drawer

(6).

Now

the

DANOLI

unit

can be inserted into

the

condenser

drawer.

The DURST

DA

900

can also be used

with

mercury

vapour lamps.

As these lamps are

of

slow

ignition, i.e.

they

need a
