    SA-AK350PL 1 Safety Precautions 1.1. General Guidelines 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, ensure that all the protective devices such as insulation barriers and insulation papers shields are properly installed.

  • Page 5: Protection Circuitry

    SA-AK350PL 1.3. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: · No sound is heard when the power is turned on. · Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
  • Page 6 SA-AK350PL 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminium foil or comparable conductive material).
