HOW TO INSTALL A DRIVE BELT ON THE TURNTABLE The drive belt is already on the underside of the turntable. Place the platter on the platter axle and use your finger to grasp the drive belt through one of the holes in the platter, near the motor.THORENS TD 204 Turntable - Figure 5Pull the belt on the motor pulley and then spin the platter so the belt can run over the motor pulley.
DUST COVER INSTALLATION

  1. Unwrap the two hinges and the dustcover.
  2. Note that the hinges have a clamp side and a tab side.
  3. Note that the dustcover has two spots on its rear edge shaped to accept the clamps.
  4. Carefully push the clamps onto the dustcover in these locations
  5. Now snap the two clamps into the areas indicated at the back of the turntable to accept them.

MOUNT AND ADJUST

  1. Place the aluminum turntable platter over the center spindle. Place your fingers through one of the access holes and grab the rubber belt and stretch it over the motor pulley. Be sure the belt is not twisted. Spin the platter a few times to be sure the belt runs smoothly. Now place the rubber platter mat on top of the platter so the ribbed sections point upward
  2. Insert the headshell into the tone arm and fix it by turning the collar.
  3. Insert the counterweight on the end of the tone arm, rotating it until it threads into place.
  4. Rotate the antiskating knob counterclockwise until it is set to “0“. Make sure the gauge is pointing in your direction
  5. Place the lever for the tone arm lift in the front position so that the lift bank lowers.
  6. Open the tone arm lock. Seize the handle of the tone arm and move it just outside the edge of the platter so that it can float up and down. Remove the protective cap from the stylus. (Be careful not to hit the stylus against anything.)
  7. Turn the counterweight until the tone arm floats level. If the tone arm moves up: Turn the counterweight counter-clockwise. If the tone arm moves down: Turn the counterweight clockwise
  8. Put the tone arm back onto the arm rest and lock it.
  9. The counterweight has a rotary ring with a scale. Without turning the counterweight, only turn the ring until the zero “0” aligns with the indicator line.
  10. The scale indicates the stylus pressure in grams. The pressure of the cartridge supplied with this turntable is 2g, turn the entire counterweight counter-clockwise to “2g” and the anti-skating to “2g“. If a different cartridge is used, adjust the stylus pressure and the antiskating indicated to the corresponding specifications.

INITIAL STARTING UP

MAINS CONNECTION
An external switching power adaptor is supplied with this turntable.
There are the RCA jack on the rear panel of the turntable. You can use it to connect to your amplifier. You also could switch the selector to “ON” or “OFF”, and connect the RCA plug to the “LINE” input of your amplifier.

  1. Place the record on the turntable. If it is a 45 rpm, you need to place the adaptor on the record spindle.
  2. Choose the playing speed.
  3. Release the pick-up arm clip.
  4. Place the cartridge vertically over the first track of the record the turntable starts turning.
  5. Lower the cue lever to place the stylus in the groove
  6. When playback is complete, push the cue lever to lift the tone arm and move it back to the arm rest.
  7. If you want to pause the playback, switch the knob to “off”, and switch it to 33 or 45 to continue the playback.
  8. After finish the playback, please switch off the power to save energy.

IMPORTANT RECOMMENDATIONS
We advise you to clean your records using a rag impregnate with an antistatic product for maximum enjoyment of your records and also to make them last.
We would also point out that for the same reason your stylus should be replaced periodically (approximately every 250 hours). Dust the stylus from time to time using a very soft brush dipped in alcohol (brushing from back to front of the cartridge).

MAINTENANCE

WHEN TRANSPORTING YOUR RECORD PLAYER DO NOT FORGET TO:
Replace the protective cap on the stylus. Disconnect the drive belt by stretching it over the motor pulley, and allow it to wrap back around the inner drive area and then remove the platter by pulling it straight up off the spindle. Put the rest clip into the pick-up arm.
