Menu fields

4460 GSM System Option and 4468 EDGE System Option
Version 12.20
Example:
TCH Type
– This selection field
enables you to choose a specific TCH type
from a list.
–
Check boxes
only need a simple yes or no. The ‘yes’ is indicated by a green
check box. To activate or deactivate the function, click on it with the mouse
or go the field and press
E
NTER
.
Example: The
Call on Loc. update
check
box is unchecked. This means that the
function will not be performed.
–
Radio buttons
allow you to select between different options, similar to
selection fields.
Example: The sine function of the audio generator radio
buttons in the picture has been selected. The other func-
tions are inactive. By selecting the rectangle function,
sine would automatically be deselected.
Select a function by clicking on the appropriate radio
button, or move to the radio button with the cursor keys
and press
E
NTER
.
Navigating to an entry field
Jump to the required area using the function keys
P
G
U
P
or
P
G
D
N
.
Select the entry field you want to make changes on with the help of the
L
EFT
or
R
IGHT
cursor keys.
The selected entry field is inverted to make it easily visible on-screen.
Entering values on numeric entry fields
There are two ways how to work with numeric entry fields: either you enter the
value using the 4400’s numeric keys or you use the selection key. The achievable
results are basically the same. However, there is no entry discard function when
you use the selection key.
– Enter the required value using the numeric keys of the 4400.
While the entry field is open, entered values can also be edited using the
B
ACK
function key.
To
confirm
the changes, push the
E
NTER
function key. To discard the
changes, just leave the entry field, e.g. using the
L
EFT
or
R
IGHT
cursor keys.
– Instead of typing in a new value, you may also turn the selection key to
increase or decrease the current value of the entry field. The
U
P
or
D
OWN
cursor keys also increase or decrease the value.
The cursor keys have a built-in ‘autorepeat function’: The value on the entry
field will be incremented respectively decremented by one step on a short
push or by a couple of steps if you push the key for a longer period of time.
NOTE
In case your entry is out of the permitted data range, the 4400 will set the
entry value to the maximum or minimum value permitted and prompt you
with
Data out of range
in the status area of the current menu.
