Functional problems
- The product does not turn whether rotate by hand or by electricity.
(1) Rotate by hand:
① A2 is missing or assembled in the wrong position.
② Deterioration of the antiskid tube causes the rubber band to slip: replace an antiskid tube P34.
(2) By electricity:
① Insert in the wrong hole: insert in the bottom hole. The top hole is to assist in rotating after power on.
② Volume is too loud: Set initial volume to the the lowest level, and turn up after the product rotates slowly.
③ After power on, there is only sizzling sound, but the product does not rotate: there may be something wrong with the circuit board, please contact customer service to re-issue the part.
④ After power on, it is normal to wait for a while until the product rotates slowly.
⑤ The handle and some gears rotate but the gramophone record does not rotate: the antiskid tube is aging, please replace it;
Reduce the spacing between the ratchet and the rubber band as shown:
The rubber band falls off from the antiskid tube onto the steel shaft:
⑥ The product rotates too slowly: set the limit speed adjustment turntable to the highest.
- Sound problems.
① After power on, there is sizzling sound, but the product does not rotate: check if the power is connected to the circuit board; check if the switch is on; check if the volume is 0.
② After power on, the product rotates without sound: check if the terminals are plugged in tightly or in the wrong position:
Check if the sound is turned on;
Check if the wires of the pickup are plugged correctly: red wire is on top, and blue wire is at bottom.
③ Poor tone quality: the product is not a professional music equipment, so the sound quality can not be the same as the professional one. Any specific sound quality problems, please contact rokronline@sercive.com, and send a sound file for customer service staff.
