turns. Also, make certain that the cueing lever is in the play position (
).
With the tonearm released from its locked position, set the bias knob and the VTF* sliding weight to 0 (zero). Move the counterweight until the tonearm is perfectly balanced (parallel to the turntable).
Setting VTF = Vertical Tracking Force (Stylus Pressure)
Set the VTF to the force recommended by the cartridge manufacturer. The VTF scale on the tonearm tube is calibrated from 0 to 4 grams with ½ gram increments. Slide the VTF weight forward until the front edge of the weight is aligned with the mark corresponding to the recommended VTF. (Fig. H)
Setting Bias Force (Anti-Skate)
We provide a calibrated scale for two type of styli (eliptical 
/ conical 
). Determine the type of stylus you are using and set the bias force knob to the number of grams recommended by the manufacturer of your cartridge (Fig. I). In most cases the bias force is calibrated to the same setting as the VTF. Always refer, however, to the cartridge manufacturer's specifications.
Connecting Your B·I·C Model 20Z Turntable to an Audio Amplifier
Audio Cables
The plugs on the audio cable are color coded to identify the right and the left channel. Red is the right channel. Insert the right channel plug into the jack marked "R" on the rear of your amplifier.
Amplifier Connections
If you are using a magnetic phono cartridge, insert the phono plugs into the space provided at the rear of the amplifier marked "phono low level" or "phono MAG."
If you are using a ceramic cartridge, insert the audio cable plugs into the high level input of the amplifier or "phono CER."
The ground wire supplied with the turntable should be connected to a suitable "ground" point on the metal chassis of your amplifier. Most amplifiers provide a convenient terminal on the rear panel for this purpose. Failure to ground this wire will result in an inordinately high hum level when attempting to play records.
Power Cord Connection
Your Model 20Z is designed to operate from a supply voltage of 105 to 130 VAC 60 Hz (50 Hz adapter available). Connection of the power cord to a higher source of voltage or to a DC power source will cause immediate damage to the unit and is not covered by the warranty. If you use this product in areas powered by 220 or 240 volts, consult your dealer for proper instructions regarding adaptation of the unit for such use.
With the programming lever set to the OFF position, plug the power cord into a suitable outlet. Many amplifiers provide convenient receptacles on their rear panels, to which the turntable power cord may be connected. Often, these receptacles (Fig. J) are labelled "SWITCHED" and "UNSWITCHED". An unswitched outlet is powered at all times. A switched outlet is powered only when the amplifier is "ON".
Operating Procedures
Before attempting to play records, make certain that the tonearm retaining lock on the tonearm rest is loosened by moving it to the right with forefinger. Most cartridges are fitted with a stylus guard or protective cover. Make certain this cover is removed or pivoted so as to expose the stylus tip.
Set the speed selector lever for the type of record you wish to play. The Model 20Z plays 12" 33 rpm records when the speed selector lever is set for 33; 7" 45 rpm records when set to 45. When playing a 45 rpm record, install the manual 45 rpm adaptor over the manual spindle, which should be placed in the center hole of the turntable. An optional multiple play 45 rpm adaptor is available. Place this adaptor over the automatic spindle to play up to six records.
Manual Play
Insert the manual spindle and move the program control knob to the manual position. The turntable will begin to rotate at the selected speed. Carefully lift the tonearm by the cueing lever, and place it on the record. After the record has been played the toenarm will return to the tonearm rest and the unit will shut off. If you wish to discontinue playing in the middle of a record, press the play button. The tonearm will return to its rest, and the unit will shut off. Alternatively, you may lift the tonearm from the record and manually return it to the rest. The turntable should then be turned off by moving the programming lever to the OFF position. DO NOT MOVE THE PROGRAMMER WITH THE TONEARM ON A RECORD.
Repeat Play of a Single Record
If you would like to hear one twelve-inch record played three times, simply advance the programmer to the number 3. With the tonearm on the pickup rest, press the play button and the unit will play the record three times and shut off.
Automatic Play of a Single Record
To play a single record automatically advance the programmer to the number 1 setting and press the play button. This initiates totally automatic operation. The arm rises, comes to the edge of the record, and is gently lowered.
At the end of record, the tonearm returns to the rest and the machine automatically shuts off. If you move the programmer to the number 1 setting and place the tonearm on the record, the unit will not shut off at the end of the record, but will continue to play the record one more time.
Automatic Record Play
To play up to six records in sequence, remove the short manual spindle from the turntable.
Place the multiple play spindle in the center of the turntable. Rotate until it lines itself up with the keyway in the center of the turntable. Press the spindle firmly down until a distinct "click" is heard.
Count the number of records you are putting on the multiple play spindle and open the record hold-down clip on the platform to the up position prior to installing records. When the records are sitting on the shelf of the spindle and the edge of the record platform . . . lower
