Attach the dust cover to the hinge pockets. Gently push the dust coverdownward until it clicks into place. Step 3. Place the belt on the motor pulley. Hold the belt and slide it onto the notch of the brass motor pulley. Motor pulley Step 4. Use your hand, slowly rotate the platter ten times clockwise as shown. Remove the ribbon from the belt. • The belt is a consumable part. Replace the belt if the playback speed slows down or irregular rotation occurs. Usually, it is recommended to replace the belt annually Turntable Platter and Belt Setup . • It’s necessary to disconnect the AC adapter before replacing the belt. For the first time, you use this Record player, you need to install the platter and belt. Step 1. Turn the platter over and you will see a raised circle. Loop the belt along the middle circle. Step 2. Attach the platter: Belt Mount one of the openings on the turntable with the Motor pulley. 4 Replacing the Stylus It is suggested to replace the stylus after 400 hours use. In addition to the deterioration of sound quality, records • Be sure to disconnect the product’s AC adapter from the outlet. • When replacing the stylus, hold the headshell and the cartridge body tightly. Rotate the front of the stylus in a forward and down motion. Installing a New Replacement Stylus 1. Mount the new replacement stylus to the cartridge. Engage in body first 2. Lift the stylus up until a click is heard. 3. Make sure there is no gap between the headshell and the cartridge. Cleaning the Stylus • When the stylus becomes dirty or dusty, please clean it with a soft brush. • It is recommended to use a stylus-specific cleaner (not included) to clean the stylus. Carefully remove dust from stylusthe base of the tip towards the tip. • Removing the Stylus • may also be damaged as the cartridge’s stylus tip wears down. 5 Connection to External Speaker with RCA Audio Cable 6 PHONO LINE DC IN 12V SERVICE ONLY Connecting Phono Pre-amplifier Use the Phono & Line Out Switch to set the output, as shown below.

FCC ID: 2A6AD1-AD07US23 RF Exposure Evaluation Limits The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , Pout = output power to antenna in mW; G = gain of antenna in linear scale, Pi = 3.1416; R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually.
