The manual you sent me was excellent. It included clear, readable diagrams and a usable parts list. I would surely use your service again. Thanks
;
Payments were processed quickly and items were exactly as described. I will use owner-manuals.com in the future for any other manual needs.

The Technics manual was very clear and I was able to solve my technical problems.
I did not think that anyone kept these manuals and was pleasantly surprised to find them on the Internet and at an affordable price.
I would recommend Owner Manuals as a first source of technical products for ‘dated’ equipment manuals.

The content of the manual was not found on the Internet and was a hard find. I check the net for 5 hours until I came across this web-site. When I did find the book it Auto loaded into my IPAD PDF shelf for books for review at anytime. Overall I am satisfied with the book and it answered all my questions. This repair book is obsolete because the product I bout it for is pretty old. Thanks for the help with the download and even having the manual. Thanks 73's K5HRD

Excellent manual including schematics. The service was great and the manual helped complete the job.
MEASUREMENT OF MICROWAVE POWER OUTPUT
¥ Microwave power output measurement is made with the microwave oven supplied at its rated voltage and operated at its maximum microwave power setting with a load of (1000±5) g of potable water. ¥ The water is contained in a cylindrical borosilicate glass vessel having a maximum material thickness of 3 mm and an outside diameter of approximately 190mm. ¥ The oven and the empty vessel are at ambient temperature prior to the start of the test. ¥ The initial temperature (T1) of the water is (10±2)¡C It is measured immediately before the water is added to the vessel. After addition of the water to the vessel, the load is immediately placed on the center of the turntable which is in the lowest position and the microwave power switched on. ¥ The time T for the temperature of the water to rise by a value � T of (10±2)¡K is measured, where T is the time in seconds and �T is the temperature rise. The initial and final water temperatures are selected so that the maximum difference between the final water temperature and the ambient temperature is 5¡K.
Â¥ The microwave power output P in watts is calculated from the following formula : P=
4187 X (DT) + 0.88 X (T2 - T0) X M T
¥ T2: Temperature after heating ¥ T0: Temperature after bowl ¥ M: Weight of bowl
is measured while the microwave generator is operating at full power. Magnetron filament heat-up time is not included. (about 3 sec) ¥ The water is stirred to equalize temperature throughout the vessel, prior to measuring the final water temperature. ¥ Stirring devices and measuring instruments are selected in order to minimize addition or removal of heat.

DISASSEMBLY AND ADJUSTMENT
A. OUTER CASE REMOVAL
1) Disconnect the power supply cord from the outlet. 2) Remove the screws from the rear and along side edges of the case. The outer case must be moved backward to be lifted off.
C. CONTROL PANEL ASSEMBLY
1) Disconnect the leadwire from the PCB SUB ASS�Y. 2) Remove the screws for the earth and securing the control panel. 3) Lift control panel ASS�Y from the oven by the tab unhooked.
B. POWER SUPPLY CORD
1) Remove the outer case. 2) Disconnect two terminals, and remove one screw of the earth terminal.
