To turn unit ON, press to LEFT. Use LA704B line adaptor to power unit from line voltage without batteries installed or to charge Ni-Cad batteries. Test for proper operation

  • Use a digital multimeter to verify that the proper voltage and current are available at the transducer connector.
  • Substitute an oscillator for the transducer.
  • Follow the connection to the power unit as shown at right.
  • The unit should have unity again. CAUTION: DO NOT ATTEMPT TO RECHARGE ALKALINES WITH THE LA704B. Alkaline batteries may EXPLODE or leak corrosive fluids.
