Warning of a hazard for the user, the unit or possible misuse.
Important notice.
The record player is supplied with a factory fitted and adjusted cartridge.
** The following
instructions for adjusting the cartridge are provided in case the cartridge is replaced by a
different model at a later date.
During assembly and adjustment of the deck small parts could be lost if not carefully placed in a suitable
receptacle. Before starting assembly make yourself acquainted with the parts listed above and correspondingly
numbered in the technical drawings above. Separately packed items are marked with an asterisk *.

Set-up
Make sure the surface you wish to use the turntable on is level (use a spirit level) before placing the turntable
on it.
Fit the drive belt (2) around the platter (3) and the smaller diameter part of the motor pulley (1). Avoid
on it.
Fit the drive belt (2) around the platter (3) and the smaller diameter part of the motor pulley (1). Avoid
getting sweat or grease on the belt as these will deteriorate the performance and reduce the belt's lifespan. Use
absorbent kitchen paper to remove any oil or grease from the outer edge of the platter and the belt.
Remove the transport lock (16) from the tonearm. Store in the original packaging so they are available for
any future transportation.

Cartridge downforce adjustment
The counterweight (4) supplied is suitable for cartridges weighing between 4 - 9g.
Place counterweight (4) halfway along the counterweight support rod at rear of arm, being sure to have the
securing screw uppermost.
With the power off, and the platter static, place the Stylus pressure gauge onto the platter (minus felt matt),
with metal tip facing but NOT over centre spindle and carefully place the tip of stylus on point marked 17,5

With the power off, and the platter static, place the Stylus pressure gauge onto the platter (minus felt matt),
with metal tip facing but NOT over centre spindle and carefully place the tip of stylus on point marked 17,5
(this represents 17,5mN or 1.75 grams pressure). If the stylus gauge becomes level, then the correct pressure
has been achieved. However if the there is insufficient or excessive pressure the gauge will either not move or
tilt down.
To adjust the amount of pressure carefully move the counterweight along the support rod until the stylus
has been achieved. However if the there is insufficient or excessive pressure the gauge will either not move or
tilt down.
To adjust the amount of pressure carefully move the counterweight along the support rod until the stylus
pressure is sufficient to raise the pressure gauge to the level position. Moving the weight towards the
cartridge will reduce pressure and away will increase pressure.
Finally secure the counterweight using hexagonal key provided.

Finally secure the counterweight using hexagonal key provided.
Please note: It is advised to remove stylus tip from gauge whilst making adjustments to avoid damage
to stylus.
Adjusting the vertical tracking angle (vta)
** Put a record on the platter. When the needle is lowered into the record groove and the tonearm is not resting
on the lift arm, the tube of the tonearm should be parallel to the surface of the record.
If it is not loosen both screws in the tonearm base just enough to allow vertical movement of the arm pillar
without force and slide the arm up or down until it is parallel.
Carefully retighten the screws without applying excessive force (which would deform the arm pillar) – finger
tight is quite sufficient.
