[Mode Control]
Pressing this enables the user to assign the CALling tones to a selected type of
modulation, see Fig. 3-1-33. Modulation, on the selected channel, is turned off when the tones
are triggered and restored after the tones have been sent. Modulation on other channels is not
affected by the CALling tones and this allows sequential signaling tones to be combined with
sub-audible tones.
[NO mod]
This option effectively inhibits sequential tones. The tone
sequence can be sent between 1 and 9 times, set by
[No. of Repeats]
, every time the
[Send
Tones]
key is pressed. Setting the number of repeats to 10 allows the tones to be sent continually
under control of the
[Send Tones]/[Stop Tones]
key at the main menu.
[Select Standard]
Selection of alternative signaling standards is achieved by pressing this key to
access the
Select Standard Menu
.

Up to 20 sequence set-ups can be stored. Use the key pad to enter the store
location number and press [enter].
