A. Tone Generator Only
If the MTG-10 is to be used strictly as a tone generator, connect pins 9 & 10 of the MTG-10 to the audio input of a pag-
ing amplifier. In this mode, no input signal is required, only a contact closure for the desired tone.
B. Tone Generation and Background Music Control
If the application requires background music to be interrupted by the tone, connect the background music source to
audio input pins 7 & 8. The audio output pins 9 & 10 connect to the audio input of a paging amplifier.
C. Telephone Recording Disclosure Tone
In some states, to legally record a telephone conversation, both parties must be alerted to the fact that you are record-
ing their conversation. One common method of reminding callers that they are being recorded is to provide a period-
ic alert tone during the call. To create a telephone recording disclosure tone at 15 second intervals, wire the MTG-10
as shown below. Then jumper pins 1 and 5 with pin 6. When the unit is powered up, it will go into alert tone mode.
Note: The shunt JP1 may be in or out.

D. Output Volume Level
The output level of the tones can be adjusted by adjusting the Output Level Control as shown in Installation section
B. This does not affect the level of the audio input.

A. Tone Group Selection
The MTG-10 features two groups of user controllable tones
selected by removing or inserting shunt JP1 (see diagram
below and chart to the right). Note: A steady 784hz tone is avail-
able by using special software model M10-CT.
Shunt JP1
B. Individual Tone Selection
An individual tone may be energized by shorting pin 6 (common ground) to the corresponding pin of the desired tone.
The tones will continue for as long as the closure is maintained. If background music is passed through the MTG-10,
it will be faded out during the tone and then faded back in.
