How do I disassemble the KENWOOD TR-3600E?
To remove the cases and PC boards of your KENWOOD TR-3600E, follow these steps:
1. Depress the release button and pull the battery pack off to the right.
2. Remove the 4 screws from the battery pack bottom plate.
3. Remove the 3 screws from the top and bottom cases.
4. Open the case towards the front by holding it with both hands as shown in the illustration. Note that indented retainers are located on the “hinge” or swing part.
5. Remove the 3 screws from the DCL unit mounting bracket.
6. After removing 4 screws, separate the RX and TX units.
7. Remove the escutcheons from the TX and RX units.
What are the initial settings and important notes for performing adjustments on the KENWOOD TR-3600E?
Before performing adjustments, unless otherwise specified, set the controls on your KENWOOD TR-3600E as follows:
Controls Setup:
POWER/VOL: OFF
KEY LOCK: OFF
TX STOP: OFF
DCS: ON
HI/LOW: HI
SQL VR: MIN
Notes:
• When adjusting the trimmers or coils, use a non-inductive tuning tool.
• When adjusting the RX section, never transmit to prevent damage to the Signal Generator (SSG).
• Connect the MIC connector as shown in the service manual diagram. The SSG output level is indicated as open circuit.
