Operation
Testing after assembly
Before you put on the first record, you should carry out a test after assembling the T700. Connect the T700 to the mains; the
STOP button on the glass surface lights up in red. The tonearm is in its holder and the needle guard underneath the cartridge
has been removed.
Now start the turntable at the low speed by touching the button on the surface. Immediately the turntable begins to turn. As
long as the target speed of 33 ⅓ revolutions per minute has not yet been reached, the lighting under the button pulsates.
Once the target speed is reached, the button lights up continuously.
For the sake of clarity, the button is only labeled with the number 33, but the speed is of course regulated to precisely 33 ⅓.
In the next step, the higher speed of 45 revolutions per minute can be tested by touching the button . Here too, the lighting
under the button pulsates until the target speed is reached.
In both cases, the target speed should be reached after 3-6 seconds. If the time is longer, the speed control should be
calibrated. This is done on the back of the T700 using the two adjusting screws of the spindle trimmer next to the power supply.
You will find a detailed explanation of this in the chapter on target
speed setting
on page 10.

Finally, the horizontal level of the installation location for the T700 can be checked with the aid of the circular level included in
the scope of delivery. The circular level (Fig. 2) is located in the accessories box and is simply placed on the surface that is to be
tested. The air bubble should remain within range of the 1 ° mark.
Playing a record
After this test, you can now put on a record. Please note the specified speed for which the record was pressed. As a rule, long-
playing records with a diameter of 30 cm require a speed of 33 ⅓ revolutions per minute, the smaller single records, with a
diameter of 7 inches (17.5 cm), require a speed of 45 revolutions per minute. The speed is often also referred to as the playback
speed. For some small 7 inch records you need a single adapter / puck (not included) that reduces the large inner diameter of a
single from 38.1 mm to 7 mm on the regular mandrel in the middle of the turntable. Alternatively, you also get plastic clips that
are clipped in and remain permanently attached to the single.
A single adapter can be safely stored in the accessory box in the compartment of the circular level.
An incorrectly selected speed does not cause any damage, neither to the needle nor to the recorder, it is only manifested
in a wrong pitch; keyword "Mickey Mouse effect"
Note on the turntable platter
The turntable of the T700 is made of POM, a type of plastic which has a very low resonance and can be specifically used without
the turntable support. If you are still a fan of turntable support, you can of course use one. For this you should note that the
height setting of the tonearm may then have to be adjusted to the higher position of the record.
How this is done is described in the chapter
Adjusting the tone arm height
on page 11.
