CAUTION: Always replace fuses with same type or rating. Failure to do so may

create a fire risk. Refer to fuse ratings listed on the label on the rear panel of the instrument

or on the table near the fuse holder. See Section 12.

Peripheral Placement

NOTE: To maintain patient safety, peripheral devices such as printers must be placed at least

Instructions

1.5 meters (4.9 feet) away from the patient, such that the patient cannot touch a peripheral

device with any part of his or her body  while being examined. In addition, the instument

operator must not attempt to touch the patient and a peripheral device at the same time while

examining the patient.

Radio and TV interference

The Humphrey Field Analyzer II has passed all domestic and international electromagnetic

emission/suppression standards. However, it still generates small amounts of radio frequency

energy and may cause interference to radio, television or other instruments. If the HFA II does

cause interference to radio or television reception, the following measures may be necessary:

• Plug the Humphrey Field Analyzer II into a different outlet so that the

   instrument and the receiving device are on different branch circuits.

• Reorient the HFA II with respect to the TV or the radio antenna.

• Move the receiving device and the HFA II away from each other.

• Use only shielded communication cables.
