INTRODUCTION AND SETUP

independent operation. Rear panel banana jacks provide access to the internal regulated power supplies (or batteries) for use as a bias source.

PREPARATION FOR USE

**********CAUTION**********

This instrument may be damaged if operated with the LINE VOLTAGE SELECTOR card set for the wrong applied AC input source voltage or if the wrong fuse is installed.

Line Voltage

When the AC power cord is connected to the unit and plugged into an AC outlet, the unit automatically switches the amplifier power source from internal battery operation to line operation. The internal batteries are charged as long as AC power is connected.

The SR560 can operate from a 100 V, 120 V, 220 V or 240 V nominal AC power source having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the LINE VOLTAGE SELECTOR card, located in the rear-panel fuse holder of the unit, is set so that the correct AC input voltage value is visible.

Conversion from one AC input voltage to another requires a change in the fuse holder's LINE VOLTAGE SELECTOR card position and a new fuse. Disconnect the power cord, slide the fuse holder cover to the left and rotate the fuse-pull lever to remove the fuse. Remove the small printed circuit board. Select the operating voltage by orienting the printed circuit board. Press the circuit board firmly into its slot, so the desired voltage is visible. Rotate the fuse- pull lever back into its normal position and insert the correct fuse into the fuse holder.

Line Fuse

Verify that the correct line fuse is installed before connecting the line cord to the unit. For 100 V and 120 V, use a 1 Amp fuse and for 220 V and 240 V, use a 1/2 Amp fuse.

Line Cord

The SR560 has a detachable, three-wire power cord with a three-contact plug for connection to both the power source and protective ground. The protective ground connects to the accessible metal parts of the instrument except for BNC shields.

To prevent electrical shock, always use a power source outlet that has a properly grounded protective-ground contact.

Ventilation

Always ensure adequate ventilation when operating the SR560. The unit will generate heat while charging dead batteries.

Power-Up

All instrument settings are stored in nonvolatile memory (RAM backed-up) and are retained when the power is turned off. They are not affected by the removal of the line cord. If the power-on self test passes, the unit will return to the settings in effect when the power was last turned off. If an error is detected or if the backup battery is exhausted, the default settings will be used. Additionally, if the RESET key is held down when the power is turned on, the instrument settings will be set to the defaults shown below:
