Edit keys are available to make changes to a list. These
keys allow you to change channels, delete channels, or
insert channels anywhere in the list. When editing, a
channel range (i.e. 1!1-1!6) and a memory location (i.e.
M1) are treated as single channel entries.

Perform the following steps
to change a channel:
A. Use the cursor keys to place the cursor at the
beginning of the channel entry to be changed.
B. Key in the new channel entry, and press the

comma.
2. Deleting a channel

try.
3. Inserting a channel
Perform the following steps
to insert a channel anywhere in the list:
A. Position the cursor at the desired location in the
list. The channel will be inserted between the
selected channel entry and the channel entry
before it.
B. Press the INSERT key. The following message
will be displayed:
INSERTING ENTRY
C. Key in the new channel entry, and press the
right cursor key ( ) or ENTER to add the
comma.

off.
4.5.3 Closing and opening channels
One of the basic capabilities of the Model 7001 is to
close (or open) one or more channels specified by the
user. All the specified channels will either close or open
at the same time. An exception to this is when the Sin-
gle Channel mode is enabled (see paragraph 4.8.4).
With Single Channel mode enabled, only the lowest
numbered channel in the lowest numbered slot will
close.
This operation is performed with the instrument in the
channel list display state. The instrument powers up to
the channel list display state.
The procedure to close and open channels requires that
you understand how to enter the channels to be con-
trolled. In general, a channel list is entered using the
keypad. The number keys are used to enter slot and
channel (row and column for a matrix card). The right
cursor key ( ) (or ENTER key) adds a comma (,)
which is used as a channel separator and list termina-
tor. The hyphen key (-) is used to define a range of
channels. Finally, the “M” key is used to enter closed
channels of a channel pattern stored in memory. For
details, see paragraph 4.5.2.
