Warning -This equipment has been certified to comply with the limits for a Class Bcomputing device, pursuant to
Subpart J of Part 15 of FCC Rules. Only computers certified to comply with the Class B limits may be attached to this
equipment. Operation with non-certified computers is likely to result in interference to radio and TV reception. This
equipment uses radio frequency energy for its operation and if not installed and used properly, that is, in strict
accordance with the instruction manual, may cause interference to radio and television reception. It has been type
tested and found to comply with the RF emission limits for a Class B computing device which is intended to provide
reasonable protection against such interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause interference to radio or television
reception, which can be determined by turning the equipment off and on,the user is encouraged to try to correct the
interference by one or more ofthe following measures:
• Move the computing device away from the receiver being interfered with.
• Relocate (turn) the computing device with respect to the receiver.
• Reorient the radio or television receiving antenna.
• Plug the computing device into a different AC outlet so that the computing device and receiver are on different
branch circuits.
• Disconnect and remove any 1/ 0 cables that are not being used. (Unterminated 1/0 cables are a potential source of
high RF emission levels.)
• Unplug and remove any circuit boardsthat are notbeing used. (Here again,unterminatedcards can be a sourceof
potenti al interference.)
• Be certain that the computing device is plugged into grounded outlet receptacles. (Avoid using A/C cheater plugs.
Lifting ofthe powercord ground may increase RF emission levels and mayalso presenta lethal shock hazardto the
user.)

PICTORIAL3
The Z-29 Terminal's keyboard has the standard 26 letters of
the alphabet arranged just as they are on a conventional type-
writer. These keys, like their counterparts on a typewriter, will
function in either upper case or lower case. For upper case,
press either SHIFT key or the CAPS LOCK key.
The CAPS LOCK key will light a keyboard indicator when
it is engaged. If the status indicator line on the Video Display
is active, it also displays a CAPS LOCK message. This func-
tion affects only the alphabetic keys.

Page 2.6
CONTROLS
NONALPHABETIC KEYS
Nonalphabetic keys, shown in Pictorial 4, serve two purposes.
In the "unshifted mode", they will displayconventional numbers
and a portion ofthe punctuation marks and special characters.
However, if you press either SHIFT key, the character printed
above the number or special character will be printed. This is
the same function you find on a conventional typewriter. The
CAPS LOCK function, on the other hand, does not shift these
keys.
