[. . . ] · Protection circuit and indicator provided. · TEST-TONE functions for easy system output checking. · Pulse power supply* for stable, regulated output power. * Pulse power supply This unit has a built-in power regulator which converts the power supplied by the DC 12 V car battery into high speed pulses using a semiconductor switch. These pulses are stepped up by the built-in pulse transformer and separated into both positive and negative power supplies before being converted into direct current again. [. . . ] The level adjustment control is set to the "MIN" position. -30 -40 Specifications Guide de dépannage La liste suivante vous aidera à résoudre la plupart des problèmes que vous pouvez rencontrer avec cet appareil.
