Section 4 topics

The hyphen (-) is used to designate a range of channels. After entering the first 

channel, as explained in Step 2, press the “-” key on the keypad to put in the 

hyphen, and then key-in the last channel. The following example shows proper for-

mat: 
SELECT CHANNELS 1!1-1!10, M1,
SCAN CHANNELS 1!1-1!10, M1,
The above display indicates that channels 1!1 through 1!10 and the channel pat-

tern stored at memory location 1 (M1) are entered.

Step 4. Repeat the basic procedure in Steps 2 and 3 to enter all required 
channels. 

Step 5. Edit the entered list as required.

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. 

1.

Changing a channel

 

 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.

2. Key in the new channel entry, and press the right cursor key or ENTER to 

add the comma. 

3.

Deleting a channel

 

 Perform the following steps to delete a channel:

a. Place the cursor at the beginning of the channel to be deleted.

b. Press the DELETE key to delete the channel entry. 

4.

Inserting a channel

 

 Perform the following steps to insert a channel any-

where in the list:

a. Position the cursor at the desired location in the list. The channel will be 

inserted between the cursor 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.

d. Press INSERT a second time to cancel the insert edit function.

5.

Deleting all channels

 

 The entire list can be cleared by pressing CLEAR 

LIST.
