Cautions
- Aqueous cleaning not recommended.
- Flow soldering not recommended; use reflow soldering.
- Model TC33 is not designed to be used with flux; use care with flux when soldering.
- It is not recommended to adjust the Model TC33X-1 past the effective rotary angle.
- If excessive force is applied to the sliding part (the operating shaft) when adjusting the resistance value, the sliding part may be deformed or broken.
