Creating the tone sequence
To create the required tone sequence, first press the [Enter Sequ] key to display the cursor in the
tone sequence panel.
Enter the required sequence by using any of the data entry keys 1 to 9, zero and the Hex digits A
to E. The [Extend Tone] key is used to convert a standard tone to an extended tone or an extended
tone to a standard tone. With the cursor positioned over the tone to be changed, each press of the
[Extend Tone] key will extend it or reduce it to standard. The cursor is moved by using the
variable control.
Editing a tone sequence
An existing tone sequence can be edited as required. Using the rotary control, move the cursor
over the character to be changed. To delete the unwanted character and insert a new character in
its place, press the data key corresponding to the new character. To delete an unwanted character
and close up the sequence, press the [DELETE] key.
Editing the tone standard
Tone frequency shifting
The frequency of all the tones in the table can be collectively altered by up to ±10% for tolerance
checking.
Tone duration
The duration times for standard and extended tones are set to the system standard when the system
is selected. They can be altered by the user from the
EDIT TONE STANDARD screen, which is
accessed by pressing the [Edit Std] key on the
SELECT TONE STANDARD screen.
Press the [Tone Durat’n]key or the [Tone Ext Dur] key as appropriate and enter the required
duration using the data entry keys and the [ms] terminator key.
Producing the sequential tone signal
The Service Monitor has four tone modes for producing sequential tone signals. These are
selected after pressing the [Send Mode] key. This will display the soft keys shown below:-
[Cont Tones] Generates the tone sequence repeatedly.
[Tone Burst] Generates one sequence of the tones then stops.
[Step Tones] Each initiation causes one tone of the sequence to be generated for the stated
duration. Subsequent initiations step to the next tone in the sequence.
[Single Tone] Pressing any data entry key will cause the corresponding tone to be
generated for the stated duration.
[Return] Returns to the main Sequential Tones menu.
The selected send mode, i.e.
Cont, Burst, Step or Single, will be shown on the display against the
legend
Tone Generate Mode.
Before sending tones using the RF generator ensure that the RF generator is ON.
