Installing the Lid

Install the Lid carefully over the hinge prongs.

Turntable Platter and Belt Setup

1. Install the drive belt over the inner ring under the platter and make sure it won’t fall off during the setup.
2. Place the platter through the turntable spindle, then rotate the platter until you see the drive motor pulley through the window at the top left corner.
3. Carefully grab the drive belt and put it around the slot of motor pulley.
4. Connect the power adapter to the turntable and power on the turntable.
5. Set the Motor Start/Stop switch to the Start position to see if the platter motor spins. If the platter does not spin, try the steps listed above again.

Cartridge Down force Adjustment

The Counterweight supplied is suitable for cartridges weighing between 3.0-6.0g.

• Gently push and turn the Counterweight onto the rear of the tonearm (with the scale facing toward the front of the turntable).

• Remove the cartridge protection cap.

• Lower the tonearm lift and position the cartridge in the space between the tonearm rest and the platter.
  Carefully rotate the Counterweight until the tonearm balances out. The tonearm should return to the balanced position if it is moved up or down. This adjustment must be done carefully.

• Once the tonearm is correctly balanced return it to its rest. Hold the Counterweight without moving it, and gently rotate the Downforce Scale ring until the zero is in line with a black line on the rear of the tonearm. Check whether the arm still balances out.

• Rotate the counterweight counterclockwise (seen from the front) to adjust the downforce according to the cartridge manufacturer’s recommendations. One mark on the scale represents 0.05g of downforce.

NOTE: The recommended downforce for the factory-fitted cartridge is 3.5±0.5g.

Anti-skating force adjustment

The anti-skating force must be adjusted corresponding to the downforce as follows:

Slip the loop of the anti-skating weight’s thread over the 3rd groove of the stub to set the correct anti-skating force for the factory-fitted cartridge. Feed the thread through the loop of the wire support.

Connection to the Amplifier

This turntable uses a moving magnetic cartridge. Set the PHONO & Line Out Switch on PHONO mode. Connect the phono out cables to the phono input on your amplifier of pre-amplifier (phono stage). Line inputs such as CD, Tuner, Tape, or Video are not suitable for phono inputs. Make sure the amplification of the selected input matches the type of cartridge being used. The factory installed cartridge is 47k ohms/MM-input.
NOTE: If your amplifier does not have an input suitable for phono cartridges, you will need to purchase a separate phono amplifier for moving magnetic cartridges. This separate phono amplifier will then connect between your turntable and your amplifier.

Stereo System Connection

Set the PHONO & Line Out Switch on LINE mode. The RCA PHONO & Line Out Jacks output analog line-level signals and could be connected directly with a par of active/powered speakers of the appropriate input of your stereo system.
The Red plug connects with the Right channel and the White plug connects with the Left channel.
NOTE: The RCA Jacks are not designed to be connected directly to the passive/unpowered speakers on LINE mode. If connected to the passive speakers, there is no sound.

Main Power Connection

The power adaptor is in the foam packing material. Unpack the power adaptor and plug the small end into the DC power jack located at the back side of the turntable. Plug the power adaptor into your power outlet.

Maintenance and Cleaning

Your turntable requires little of no regular maintenance. Remove dust with a slightly damp antistatic cloth. Never use a dry cloth, this will create static electricity and attract more dust! Antistatic cleaning agents are available at specialist stores, but must be applied sparingly to avoid damage to rubber parts. It is recommended to install the needle cover before cleaning or maintenance is carried out to avoid damage.
If the turntable is not used over a long period of time, the drive belt should be removed to prevent unequal stretching.

NOTE: Always disconnect the record player from the power supply as a precaution before maintenance!

Useful Tips
The turntable should be positioned on a low-resonance surface such as wood or multiple layer ply board to avoid structural vibrations disturbing playback.

Cartridge Replacement

1. Before replacement, put the stylus protector back on the stylus to prevent damage to the stylus during the replacement process.

2. Carefully remove the wire leads from the original cartridge.

3. Loosen the two screws on the headshell that are securing the cartridge and then remove the original cartridge.

4. Mount the new cartridge to the headshell and tighten it lightly. Do not completely tighten the screws at this moment.

5. Connect the wire leads to the new cartridge’s terminals. The wire lead color codes are as below:
   White Left channel positive (L+)
   Black Left channel negative (L–)
   Red Right channel positive (R+)
   Black Right channel negative (R-)

6. Adjust the cartridge’s position to make sure it is precisely aligned on the headshell so that the stylus will be tracking the grooves in parallel perfectly.
   To achieve this, place the included paper cartridge alignment protractor over the turntable spindle, carefully lift the tone arm and place the tip of the stylus on the points marked 130mm and 250mm respectively. Fine-tune the cartridge’s position on the headshell until the cartridge is perfectly in parallel with the reference lines at both points.

7. Tighten the screws completely once the perfect alignment is achieved.

NOTE: If you are unfamiliar or uncomfortable with completing this procedure, we recommend consulting with a professional to perform the installation.

Potential Incorrect Use and Fault Conditions
These turntables are manufactured to the highest standards and undergo strict quality controls before leaving the factory. Faults that may possibly occur are not necessarily due to material or production faults but can sometimes be caused by incorrect use or unfortunate circumstances. Therefore the following list of common fault symptoms is included.

• The unit is not connected to the main power supply.
• No power at the outlet.
•  Drive belt is not installed or has slipped off.
• The unit automatically switched in standby mode, power OFF and ON again on the backside.

• Amplifier not switched on.
• Amplifier or speakers muted.
• No connection to the speakers.
• No connection between turntable and amplifier.
• Wire leads not connected the cartridge.

Strong hum on phono input:

• No ground connection from cartridge, arm, or arm cable to amplifier or ground loop.
• Turntable too close to speakers.

Distorted of inconsistent sound from one or both channels:
