9.3. Carrier Frequency Adjustment
In this adjustment, two frequencies, which are for audio L-ch (2.3MHz) and R-ch (2.8MHz) signals on the IR PCB, can be set to the
target frequencies by using the variable resistors (VR400 and VR450).
target frequencies by using the variable resistors (VR400 and VR450).
You should pick up the L/R mixed signal on the IR PCB and separate them by the BPF, and then set to each frequency.
<Preparation>
∙
Dedicated Tool
∙
Frequency Counter
∙
Power Supply (9V)
<Adjustment Point>
∙
VR450 on the IR PCB for L-ch
∙
VR400 on the IR PCB for R-ch
<Target Frequency>
∙
L-ch (VR450): 2305 ±5 kHz
∙
R-ch (VR400): 2805 ±5 kHz
<Adjustment Procedure>
1. Insert the connector of dedicated tool to CN450.
2. Turn the power on.
3. Change the L/R switch to L-ch side.
4. Adjust VR450 (L-ch) for the target frequency while confirming it by the frequency counter.
5. Change the L/R switch to R-ch side.
6. Adjust VR400 (R-ch) for the target frequency while confirming it by the frequency counter.
7. Turn the power off and remove the connector to finish the adjustment.
