Top class product, I printed it out on A3 paper and it is clear and very easy to follow.
Cheaper than buying a new radio!
 ;
is part of the manual is very useful for repairing
Here are circuit diagrams
if there is damage, I recommend using this part of the
a complete list of circuit boards and components

SECTION 4 ELECTRICAL ADJUSTMENTS
Notes: 1. These adjustments are performed in the order that they are described. 2. Adjustment and measurement are performed for each channel unless otherwise specified. 3. Adjustment is made for the right channel first and then the left channel. 4. The power voltage is supplied with 9 V. Oscillation Frequency Adjustment Setting:
digital frequency counter
Adjustment Location:
� TX board (side A) �
TP (A MUTE)
LED board TP03 or TP04 (L-ch) TP05 or TP06 (R-ch)
+ �
Adjustment method: � Perform this adjustment without signal. 1. Connect TP (A MUTE) to ground on the TX board (to set the mute state), or use the test mode to set the mute state (see page 7). 2. Connect a digital frequency counter to TP03 or TP04 for L-ch and TP05 or TP06 for R-ch on the LED board. 3. Adjust L51 (L-ch) and L1 (R-ch) on the TX board so that the reading on the digital frequency counter is each within 2.3 MHz (L-ch) and 2.8 MHz (R-ch). Specified value: L-ch R-ch
� LED board (conductor side) �
TP05 TP06
L51 L1
2.298 to 2.302 MHz 2.798 to 2.802 MHz
RF Level Adjustment Setting:
digital voltmeter TP03 LED board TP03 or TP04 (L-ch) TP05 or TP06 (R-ch) + � TP04
Adjustment method: � Perform this adjustment without signal. 1. Connect TP L (L-ch) and TP R (R-ch) to ground on the LED board (to set the mute state), or use the test mode to set the mute state (see page 7). 2. Connect a digital voltmeter to TP03 or TP04 for L-ch and TP05 or TP06 for R-ch on the LED board. 3. Adjust RV51 (L-ch) and RV1 (R-ch) on the TX board so that the reading on the digital voltmeter is 480 mV. Specified value: L-ch R-ch
� TX board (side A) �
