Connector replacement

Tightened the connector finger-tight. To avoid over-tightening and possibly damaging the connector, do not use a tool
to tighten it.

Fuse replacement

The instrument is protected by a fuse placed in series with the power line input. The fuse is conservatively rated and should
never open through the life of the instrument. A blown fuse would generally indicate a problem with the instrument which
requires factory service. It is recommended that you arrange to have the instrument serviced if you experience a blown fuse.
Instrument calibration
The instrument uses digital calibration of the output buffers. To maintain the accuracy of the output amplitude and offset,
annual calibration is recommended. Contact Tektronix to schedule instrument calibration.
Repack the instrument for shipment
If the instrument is to be shipped to a Tektronix service center for repair, attach a tag showing the following information:
Name of the product owner
Address of the owner
Instrument serial number
A description of the problems encountered and/or service required
When packing an instrument for shipment, use the original packaging. If it is unavailable or not fit for use, contact your
Tektronix representative to obtain new packaging.
