Appendix B: General Information

The Cleaning of Clear Dome Cover

To obtain constant clear images, the user should clean the dome cover periodically.

l Be very careful when cleaning. Hold the dome cover ring only to avoid touching the acrylic dome cover. The

acid from fingerprints will corrode the coating and any scratches on the dome cover may cause distorted or

poor images.

l Use a soft dry cloth or a similar to clean the inner and outer surfaces.

l For more stubborn contamination, use a neutral detergent. Any cleanser for high-grade furniture is

applicable.

Troubleshooting

1. To avoid problems and to ensure the PTZ has been correctly setup it is always advisable to test the

equipment in your workshop before you go on-site. If workshop setup is successful, any problems experienced on-

site will be greatly minimized.

2. Always read these instructions before you connect the equipment to any power supply and check that you are

using the correct rated power supply and voltage. Never connect non-regulated power supplies.

If you are having problems with no video, power the PTZ and plug the video cable direct into your monitor.

If still no video then check if PTZ is running the initial self test. If not check power to the PTZ, cables and

connections. Remember that every PTZ is tested before despatch to you so it will be very unlikely to be a faulty

PTZ unit. Note that video loss can occur on a long cable run, or loss of signal strength resulting in no video, poor

quality video or even video in black and white mode. Ensure the termination jumper is correctly set in the PTZ

dome head. This is accurately detailed in this manual.

3. If video is okay but the telemetry is not working then check the dipswitch settings in the dome agree with the

settings in the control unit i.e keypad or DVR. The dipswitches set the protocol, baud rate and PTZ address.

Ensure that the RS485 cable connecting the PTZ to the control unit is connected the right way around.
