WARNING

Troubleshooting

If your instrument is still in warranty we strongly recommend that you send the entire unit back to Agilent Technologies for repair.

A procedure for checking the fuses and power supply is given on page 6-4.

•To avoid electrical shock, do not perform any servicing unless you are qualified to do so.

•Disconnect the product from all voltage sources while it is being opened. The opening of covers or removal of parts may expose dangerous voltages.

•The power cord is connected to internal capacitors that may remain live for five seconds after disconnecting the plug from its power supply.
