**The following instructions for adjusting the cartridge are provided in case the cartridge is replaced by a different model at a later date.

Installing the Lid
Install the Lid carefully over the hinge prongs.
Installing the Headshell
Insert the Headshell into the front end of the Tonearm Assembly. While holding Headshell firmly into the front end of the tonearm assembly, turn the Headshell Locking Nut counter-clockwise to firmly secure the Headshell to Tonearm Assembly.

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 6.0-8.0g.
– 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 tonearm rest and 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 Down force Scale ring until the zero is in line with black line on the rear of the tonearm. Check whether the arm still balances out.

– Rotate the counterweight counter clockwise (seen from the front) to adjust the down force according to the cartridge manufacturer’s recommendations. One mark on the scale represents 0.05g of down force.

NOTE: The recommended down force for the factory fitted cartridge is 1.8±0.2g.

Locate the anti-skating weight

You will find a anti-skating weight with small fishing line from the package, please follow below steps to locate the anti-skating weight:

1.  Slip the looped end of the fishing line over the anti-skating weight adjustment stub and into Groove 3rd (the correct anti-skating force for the factory-fitted cartridge).
   

2. Pull the anti-skating weight slightly to let the tie of the fishing line move to the stub.

3. Lift the anti-skating weight over the anti-skating weight wire support.
   The anti-skating weight should now be dangling in free space to the left of support.
   Slip the loop of the anti-skating weight’s thread over the 3nd 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.

Anti-skating force adjustment

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

Down force
1 – 1.25g
1.25 – 1.5g
1.5 – 1.75g
1.75 – 2g| Groove in the stub
1 st from bearing rings
2 nd ” ” ”
3 rd ” ” ”
4 th ” ” “
---|---

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.

Stereo System connection

RCA Jacks

• The RCA Jacks of this unit are shared as both the Phone output jacks and the Line output jacks. They are determined by the Phono/Line Switch.

• When used as a line output, the jacks output analog line-level signals and could be connected directly with a pair of active speakers or the appropriate input of your stereo system. When used as a Phono output, they should be connected to the phono pre-amplifier or the phono input of the stereo system.

• The Red plug connects with the Right channel and the White plug connects with the Left channel.
  Note:

• If the Phono/Line switch is set at LINE position but RCA jacks connected to the stereo system’s phono input, the sound might be distorted due to input overload and could damage your stereo system.

• If the Phono/Line switch is set at PHONO position but RCA jacks connected to the stereo system’s line input, the volume will be very low due to lacking signal pre-amplification.
  RCA Jack is not designed to be connected directly to the passive/unpowered speakers and if it does, the volume will be very low.

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+)
   Blue Left channel negative (L–)
   Red Right channel positive (R+)
   Green 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.
