Figure 15
Once the camera head is removed from the spring,
the locking sleeve can be seen holding the connector
to the back of the camera. The safety cables are
mounted to a rotating portion of the sleeve, which
helps prevent their twisting.
Figure 16
The locking sleeve has been removed by the camera
back by rotating it counter-clockwise (when viewing
the camera from the back). The connector is now all
that holds the camera on.

The camera head is now removed. Note that these
connectors are the same style as those found through-
out the system.
Locating Faulted Components
The basic idea in troubleshooting the system is to use
the camera head to eliminate suspected components.
Here are the areas we will try to isolate the fault to: cam-
era head, reel/dolly, interconnect cord, Monitor
+
VCR
power pack. As a scenario, we will assume that the
symptom is no video, no lights.
1. Remove the camera from the spring assembly.
2. With the Monitor
+
VCR power pack set up for opera-
tion, plug the camera head directly into the back of
the Monitor
+
VCR/power pack where the intercon-
nect cable is usually connected. Turn on the sys-
tem and check the Monitor
+
VCR for a picture. If
there is a good picture with proper lighting, the
problem is somewhere between the interconnect
cable and the spring assembly. Proceed to step 4.
If there is no picture, the problem is probably in the
camera head or Monitor
+
VCR power pack.
3. To virtually eliminate the Monitor
+
VCR, play a tape
on your Monitor
+
VCR with a VCR through the video
in jack at the rear (VCR – video out; Monitor
+
VCR –
video in). If you get a good picture, it is almost cer-
tain the problem is in the camera head. The power
pack is a little more complicated to troubleshoot, so
contact Ridge Tool Company if you suspect it is
faulted.
4. Plug the interconnect cable into the Monitor
+
VCR
and power pack. Unplug the other end of the inter-
connect cable from where it plugs into the reel-hub,
and plug the camera head into this end. Turn on
the system and check the monitor. If you get the
video and lights back, the problem is likely in the
push cable or hub. If there is no picture, the inter-
connect cable is the likely fault.
5. Once you suspect a component, contact Ridge Tool
Company Technical Services. We will establish a
plan of action to get your system back on line.
6. For additional troubleshooting suggestions, please
refer to Chart 1.
Re-Installing Camera Head
1. Lay out enough cable to lay the spring assembly
on a convenient work area and set the brake.
2. Plug the connector at the spring assembly into the
camera head, making sure that the guide pins/sock-
ets are aligned.
3. Grasp the camera head and safety cables with one
hand and turn the ribbed portion of the locking
sleeve to screw it into the back of the camera.
IMPORTANT: Try not to twist the cord or the camera,
only the locking sleeve. If this is done
properly, the cord and safety cables will
not be twisted around each other when
you view them from between the windings
of the spring.
4. Once the locking sleeve is tight into the back of the
camera, thread the spring onto the camera and,
