 ;
This is a high quality manual with clear schematic and components layout diagrams ; with service procedure included.
 ;
This service manual for the Kenwood KT-990D was reproduced really well ,is very legible and manual is complete.Combined with the low price paid,in the future,I will be checking Owner-Manuals.com any time I need a manual.
;
When I purchased this manual I had my doubts regarding the quality as the price was so reasonable as compared to other outlets.
The manual itself is of high standard the print is very clear as are the diagrams. Obviously with the diagrams one has to zoom in otherwise it is to small to be able to read.
Overall I am very pleased with the company who delivered as they said and with the manual they supplied.
I occasionally require a manual and now having registered with this company I shall order from them in the future.
;
I was at first dubious about payiong for downloaded manuals but having done so, I was extremely impressed with quality of the two manual I ordered, well worth the small price I paid.
I would highly recommend these to my friends.
;
reasonable price for the schematic - the service is perfect, all as expected and pointed by instructions - good scan of the original plans - thank you!

6.2.6 Audio Module Tuning Instructions
6.2.6.1 TX-Audio
- feed a 1 kHz sine signal of 4.0Vrms to connector pin 5 (via local box, GENconnector) - enter 0 # and 21 # and 215 # (read phone level) - change the signal frequency to 2 kHz at 4.0Vrms - if the RF module is present, enter also 31 # - if the RF module is not present, connect an oscilloscope to the X-RF connector pin 17. - enter 201 # 4 and use the +/- keys to adjust the oscilloscope to show 2075...2125mVpp and press the F key. If the RF module is present, set the deviation to 4,5...4,7 kHz and press the F key.
- change the input sine signal to 1 kHz at 400mVrms. - press 1 and use the +/- keys to adjust the oscilloscope to show 1510...1530mVpp and press the F key. If the RF module is present, set the deviation to 2,95...3,05 kHz and press the F key. - press the C key.
Check the deviation limiter as follows and tune if necessary: - change the signal level to 4.0Vrms keeping the frequency at 1kHz. If the deviation does not exceed 3.7 kHz, enter 217 # and raise the tuning value with the + key one step at a time until the deviation rises above the limit, and press the F key. If the deviation is already above 3.7 kHz, press the F key. - change the frequency to 650 Hz. If the deviation exceeds 4.7 kHz, use the + key to increase the tuning value one step at a time until the deviation drops below the limit, and press the F key. If the deviation is already below 4.7 kHz, press the F key.
