BULLETIN # 929
MODEL: TS-140S
SUBJECT: MOMENTARY TRANSMISSION WHEN VOX IS TURNED ON

When the VOX switch is turned on immediately after the power switch is 
depressed, the TS-140S may trip into the transmit mode. This condition 
can be corrected by changing the value of chip capacitor C504 on the 
Signal unit. The following procedure will detail how to access the capacitor.

REQUIRED PARTS:

C504 0.001uF, 50V chip capacitor. KENWOOD PART # CK73FBlH102K

1. Disconnect the TS-140S from the antenna and power supply.

2. Remove the top and bottom covers (12 screws). Remove the 4 subchassis 
   mounting screws. Swing the sub-chassis to the left to expose the 
   Signal unit. If required, refer to the instruction manual for illustrations.

NOTE-REFER TO FIGURE ONE FOR THE NEXT TWO STEPS.

3. Unplug the wires at connectors CN4, CN12, CN18, CN19, and CN20.

4. Remove the nine screws from the signal unit.

5. Slide the Signal unit forward until the external speaker jack clears 
   the back panel cutout.

6. Carefully lift the Signal unit up from the back side and rotate it 
   toward the front panel to expose the bottom of the board.

7. Locate chip capacitor C504 on the bottom of the board (see figure 2). 
   If required, refer to the service manual board diagrams for details.

8. Unsolder and remove C504.

9. Install and solder the .001uF capacitor in place of C504.

10. Assemble the transceiver by reversing the above steps.
