Manuels !

Everything was great, the manual, the response time, the simplicity of the order, and the
Price. The only thing that I could possible say on a negative note would be that the manual I ordered was more for a service tech. There were a lot of schematic diagrams that didn't help me solve the problem. However I would order again and recommend the web sight to others.

IMPORTANT SERVICING NOTES
Only qualified service personnel are allowed to carry out maintenance and repair of this receiver.
Servicing of High Voltage System and CRT
It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver. Note the following: � The CRT in this receiver employs Integral Implosion Protection. � If the CRT has to be changed it MUST be replaced with the correct type for continued safe working. � DO NOT lift the CRT by its neck. � When handing the CRT, ensure that shatterproof goggles are worn. � Ensure that the CRT is discharge before handling.
X-Ray
This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in close proximity to the receiver for long periods of time. To reduce any risks associated with this, please observe the following precautions: 1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 31 KV, (at a instantaneous beam current of 1000 µA). 2. Ensure that during normal operation the EHT does not exceed 28 KV (at a beam current of 1200 µA). This level has been preset in the factory. Always check that this level has not been exceeded after carrying out any repair on the receiver. 3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause excessive x-ray radiation.
Before returning the receiver to the customer
In addition to the above checks, the following should also be carried out before returning the receiver to the customer. 1. Inspect all the leads to ensure that they are dressed correctly and that they are not obstructed or pinched by any other parts. 2. Ensure that all protective devices are in good condition. These will include nonmetallic control knobs, insulating fish papers, cabinets backs, compartment covers or shields, mechanical insulators, etc.
