Audio And Visual System: Precaution

OBSERVE HANDLING AND OPERATIONAL PRECAUTIONS
1. Please explain to the customer that when the negative terminal is disconnected from the battery, the channel information memory of the AM/FM broadcast stations in the radio receiver is cleaned. If necessary, make a note of the recorded channel information before the negative terminal is disconnected, then reset the information after the negative terminal is reconnected.
2. The removal/installation of the radio receiver should be performed after all the cassette tapes and audio CDs are ejected from the radio receiver.
  HINT:
  
  If audio CDs cannot be ejected due to the malfunction of the radio receiver, do not try to drag then out by force. Bring the vehicle to the repair plant.
3. Fasten the earth bolt securely when the antenna cord is removed or installed.
  HINT:
  
  Failing to fasten the earth bolt securely causes noise at the time of radio wave reception.
4. Do not touch the cone paper of the speaker.
