The and keys are used to change the character at the cursor, and they cycle through
the available characters:

respectively (see section 4.2). It is also possible to enter a number directly by pressing
to or to (for 6 to 9 and 0). Pressing inserts a space while (ZAP!)
deletes a character, and all of the keys automatically repeat if held for a short while.
returns to the ‘TOLERANCE TO EDIT’ prompt (fig. 5.5).
The LA102 tolerance editor gives a description of the tolerance entry at the cursor
position, for example:
FREQUENCY RESPONSE, 6.3kHz, or NOISE, WTD.
It is often convenient to copy a pre-defined tolerance to create a slightly different version
without re-entering the entire tolerance - perhaps to modify the pre-defined Studer A812
tape tolerance to more accurately match a different machine, for example. This can be
achieved by pressing
] while the editor screen (Fig 5.5) is displayed, until the desired
pre-defined tolerance title is displayed, then press
to view the definition, to
enable copying, and finally the user tolerance number to which you wish to copy. Note
that all pre-defined tolerances must be copied to a user tolerance before they can be
changed.
Pressing
(or resetting by tapping ) will leave the chosen tolerance in non-
volatile memory ready to be selected by setting configuration option T to its tolerance
number.

It is often useful to print tolerance definitions on a printer for future reference, and this is
readily achieved by pressing
from the tolerance editor menu to print all of the
defined tolerances. When printed the ‘±’ symbol will be expanded to ‘+-’ characters as it
is not a standard ASCII character and not available on all printers.
Each of the 10 user tolerances may be up to 255 characters in length. Because of the way
RAM is shared in the LA102, sequence results memories 4&5 are lost (reducing the total
number of memories from 6 to 4) when user tolerances are defined and any attempt to
perform a memory operation with memories 4 or 5 will then be ignored. To reclaim
sequence memories 4&5 all of the user tolerances must be cleared by using the reset
menu (
and then ) or by deleting each tolerance in turn (using .
