camera head and the cable to the lighting ring
can sustain damage.
1
Unscrew the union nut (SW 32). Use a second
open-end spanner (SW 17) to provide counter-
force, gently making an opening in the spring to
grip with this spanner.
2
Carefully remove the protective camera glass.
Attach new protective camera glass together
with O-ring.
3
Screw the union nut back on using an
open-end spanner. Use a second open-end
spanner to provide counter-force and observe
correct tightening torque!
ROCAM® Mini Module (optional)
Tubes with diameters from 40-100mm can be
inspected using the ROCAM
The reel cable is secured for transportation with
cable ties. Do not remove the cable ties until the
reel holder has been assembled.
1
Secure the reel holder to the ROCAM
3 screws.
2
Undo the cable ties and remove the ROCAM
Mini Module reel cable.
3
Remove the ROCAM
unscrewing the union nuts, partially removing
the camera head and loosening the cable gland.
4
Affix the ROCAM
®
The adapter must be seated in the spring
groove!
After finishing work unscrew the ROCAM
Module again. Lay the ROCAM
cable in the reel holder. Lock the camera and the
adapter in position in the reel holder.
When rolled up the diameter must not be less
than 300 mm!
The camera should only be pushed or pulled
lengthwise!
Too small a radius and crosswise pushing and
pulling can cause the cable to fracture!
ROCAM location (optional)
®
A locating probe integrated in the camera head
transmits magnetic fields which are detected by the
locating receiver and are optically and acoustically
translated.
In addition to brickwork, stone, wood and plastic,
the low-frequency measuring system can penetrate
metal. The location of the probe can therefore even
be detected in cast iron pipes.
The intensity of the signals changes depending on
the position and range of the probe.

Prior to inserting the camera head and locating
probe into the tube system, test the equipment:
Swtich the receiver on with the rotary button
and set the volume at a moderate level.

Hold the receiver near the camera head and
observe the signal!
Test 1: Hold the receiver as shown in the left-
hand picture and change the distance. The
further the distance from the camera head, the
weaker the signal.
Test 2: Slowly turn the receiver 90° as illustrated
in the right-hand picture without changing the
distance. The further the receiver is turned to an
angle of 90° the weaker the signal.
Test 3: Leave the receiver at a 90° angle to
the camera head, maintaining the same distance,
and move the receiver parallel to the camera
head. If the receiver head is at exactly the same
height as the locating probe the signal will die
out. The signal will be restored by moving the
Fig. H
receiver again.
These techniques are used to "track" down the
locating probes in the tube system.
Memorise the sound of the signal in order to
be able to distinguish it from other interference
noises.
Avoid interference fields, Wherever possible,
switch off sources of electric current conduction,
transformers, motors, contactor relays, monitors,
® fluorescent lamps and energy-saving lamps.
2
Locating the probe.
Turn the receiver and observe the pointer
throw. Move in the direction where the signal
is strongest. When the pointer throw is at
maximum (from approx. 1 m away from the
probe) continue the fine locating acoustically.
Locating from longer range – optical
Locating at shorter range – acoustic
Mini
Acoustic locating is more precise but can only
be used at short range because of interference
noise.
3
Calculate the exact position by minimum
localisation.
The probe can be located more precisely
by means of minimum localisation (loss of
signal at a certain point). The camera head is
located approx. 11 cm from the receiver head
lengthwise.
General points:
Fig. I
Ensure that the batteries in the transmitter have
sufficient capacity. If the red LED is lit up replace
the batteries.
The sound can be transmitted via the built-in
speaker or via headphones. The speaker switches off
automatically if the headphone cable is plugged in.
