ranging from 48 to 440 Hz. No line voltage selecting is necessary. Instru¬

The power cord must match the power-source outlet; if it does not, con¬

Figure 1-2 for optional power cords available.
The detachable three-wire power cord has a three-contact plug for con¬

held to the rear panel by a clamp. The protective ground contact on the
plug connects (through the power cord protective-ground conductor) to
the accessible metal parts of the instrument.
