Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will no occur in a par- ticular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an output on a circuit different from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
•A shielded cable must be used when connecting a peripheral to the serial ports.
Appendix A: Troubleshooting the IntelliScope System
This section is intended to help you if you are encountering any problems with your IntelliScope system. If this information is not useful to you in determining the source of the problem, contact Orion Technical Support via phone or email.
Azimuth encoder, in general
1.Is the azimuth axis screw’s hex lock nut tight enough? Is it too tight? Remember, it should be tightened 3/16 to 1/4 turn past when the fender washer is no longer loose under the nut.
2.Does the brass bushing extend slightly above the top surface of the top baseplate? If not, the bushing or top baseplate may need replacement, or there may be an assem- bly problem.
3.Is the azimuth encoder disk (magnet) bent? If so, you will need to flatten it by bend- ing.
4.Is the azimuth encoder board trimmed flush on the side in contact with the top base- plate? If not, the board will not seat flat against the baseplate and this may cause the encoder’s sensors to come too close to the encoder disk.
5.Is the brass bushing properly registered with the azimuth encoder disk? The feature on the front of the bushing needs to seat into the hole in the disk.
Altitude encoder, in general
6.Is the altitude encoder disk significantly bent? If so, the altitude encoder assembly will need replacement. Also, if the altitude encoder mounting screws are loose, there is an increased chance of the user bending the altitude encoder disk.
