Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

I've been in the electronic business for a long time. I used to buy Sam's Photofact for my needs which intailed having to go to the store and paying about $20 for a package of 3 different units so I was forced to buy more than I needed just to get one.
Owner manual is just at your keyboard and the information is almost instantansouly and the cost is very reasonable. Easy to print out if needed or simply read off of the screen. The larger the screen the better for obvious reasons.

Very good manual, at a very good price. Received in a timely manner

Only thу cover has poor quality, internal material has excellent quality - exactly what I needed
Thanks!

Had everything I needed. Onyly took a few hours after paid for by PayPal. The copy was very readable.
SECTION 3 ELECTRICAL ADJUSTMENTS
Note: 1. The adjustments should be performed in the order given. 2. The transmitter (TMR-RF950R) already checked and adjusted should be used.
3-1. Receiving Frequency Check and Adjustment
Preparation:
AF OSC ATT + + � � TMR-RF950R Transmitter MDR-RF950 Headphones
+ �
5m
600 �
AUDIO IN (Lch) 1 kHz 316 mVrms
[RX-BASE board] � Conductor Side �
DC voltmeter
oscilloscope
+ �
Procedure: 1. Set the channel of the transmitter to CH2. 2. Turn OFF the noise filter switch on the transmitter. 3. Enter 1 kHz 316 mVrms signal only to the Lch on the transmitter. 4. Place the transmitter away from the headphone (MDR-RF950) more than 5 m. 5. Set the volume control (RV301) on the RX-BASE board to the minimum position. 6. Set the tuning control (RV302) on the RX-BASE board to the center position. 7. Connect a DC voltmeter and an oscilloscope between IC301 pin @¡ and ground on the RX-BASE board. 8. After confirming that demodulated 1 kHz waveform (about 13 mV) appears on the oscilloscope, check that the DC voltmeter indicates DC1 V to 1.2 V. 9. If demodulated 1 kHz waveform does not appear on the oscilloscope, or if the voltage is out of the specified value, adjust the air-core coil (L301) on the RX-BASE board so that the demodulated 1 kHz waveform appears on the oscilloscope, and under this condition, adjust finely the air-core coil (L301) so that the DC voltmeter indicates DC1.1 V. 10. Finally, check that signals are received when the channel is changed over to CH1/CH3 on the transmitter, then when the tuning control (RV302) on the RX-BASE board is rotated. Adjustment Location: RX-BASE board (See page 9.)
