4.3 Cartridge and Tonearm Setup

The TD-235 typically comes with an AT-95E cartridge pre-installed. If not, carefully mount the cartridge to the headshell following the cartridge manufacturer's instructions.

1. Counterweight Adjustment: Slide the counterweight onto the rear of the tonearm. Adjust it until the tonearm is balanced and floats horizontally. Lock the counterweight in place.
2. Tracking Force Setting: Refer to the cartridge specifications (e.g., 2.0 grams for AT-95E). Rotate the numbered ring on the counterweight to the desired tracking force without moving the counterweight itself.
3. Anti-skating Adjustment: Attach the anti-skating weight to the small fishing line and loop it over the anti-skating rod. Set the anti-skating force to match the tracking force.

5. Operating Instructions

5.1 Powering On/Off

The turntable powers on automatically when the tonearm is moved over the platter and powers off when the tonearm returns to its rest or after the record finishes playing.

5.2 Speed Selection

Use the speed selector switch, typically located on the front left of the plinth, to choose between 33 1/3 RPM for LPs and 45 RPM for singles. Ensure the correct speed is selected for the record you are playing.

1. Place a record on the felt mat on the platter.
2. Unlock the tonearm from its rest.
3. Gently lift the tonearm using the cueing lever.

4. Lock the tonearm in its rest position. The platter should stop spinning shortly after.

6. Maintenance

6.1 Cleaning the Stylus

Regularly clean the stylus using a soft brush designed for stylus cleaning, brushing gently from back to front. A dirty stylus can degrade sound quality and damage records.

6.2 Cleaning Records

Keep your records clean to prevent dust and debris from accumulating on the stylus. Use a carbon fiber brush or a record cleaning solution and cloth before each play.

6.3 Cleaning the Turntable

Wipe the plinth and dust cover with a soft, dry, lint-free cloth. For stubborn marks, a slightly damp cloth can be used, followed by a dry cloth. Avoid harsh chemicals or abrasive cleaners.

6.4 Drive Belt Replacement

The drive belt may stretch or degrade over time, affecting speed stability. Replace the belt if you notice inconsistent speed or if it appears worn. Refer to section 4.2 for installation.
