Thanks God for the internet and thanks for the service like this - proffessional solution on time.
;
About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.

The downloaded quality was as good as the orignial

This is a great and complete Service Manual for the Sharp GF8585HB. Giving full and detailed technical insight. Good to find these manuals online.

Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again

HANDSET SECTION
3. Checking TX output Setting:
peak power meter + � ANTENNA TERMINAL
� Make the set in Test mode (see page 11) 1. Checking RX I&Q Output Level Setting:
oscilloscope + � level meter + � TP520: RXIP TP521: RXIN TP522: RXQP TP523: RXQP TP553: GND
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Place the handset in the Continuous Transmit mode (1CH, High power). 2. Measure the ANT OUT output of the RF module in the handset using a peak power meter. 3. Confirm that the measured output is 29 mW (MIN 17.4 mW). 4. Also, execute steps 1 through 4 for the channels 2 � 20.
Procedure: 1. Place the handset in the Continuous Receive mode (1CH, LNA, AGC ON). 2. Set the SSG frequency to the frequency on 1CH + 300 kHz, and the RF output level to �95 dBm. 3. Measure the output lvel of RXIN, RXIP, RXQN, and RXQP with a level meter. At this time, confirm with an oscilloscope that a sine wave of 300 kHz is output. 4. confirm that the measured output level is �23.3 to �20.9 dBV. If IC502 was replaced (there is no ID data), the output level is �28.3 to �25.9 dBV. 5. Also, execute steps 1 through 4 for the channels 2 � 20. * for the frequency on each channel, see page 7.
2. Checking TX Center Frequency Setting: � short: TP555 � TP553
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP555 and TP553 (GND) on the MAIN board in the base unit. 2. Place the handset in the Continuous Transmit mode (1CH, High power). 3. Measure the ANT OUT frequency of the RF module in the handset using a frequency counter. 4. Confirm that the measured freuquency is 903.600 MHz ± 27 kHz. 5. Also, execute steps 1 through 4 for the channels 2 � 20.
