These external switch connections work in parallel with their associated buttons
on the DMMTT. If either of the buttons have been enabled for external use, a
TRS plug must be inserted into the TAP SW jack. In this circumstance, if a TS
plug is inserted into the TAP SW jack it will be equivalent to holding down
whichever button has been enabled for external use, without the ability to
release the button.
9V PWR JACK – Connect the output plug of the supplied AC Adaptor into the
9V power jack at the top of the DMMTT. The DMMTT’s current requirement is
200mA at 9VDC. The polarity of the power jack is center negative. The maximum
allowable power supply voltage is 10.5 VDC.
FACTORY RESTORE
The Feedback Hold setting, along with the original EXP. MODE and TAP DIVIDE
mode, can be restored to their original factory settings by holding down the EXP.
MODE button during start up.
Press and hold the EXP. MODE button, then apply power to the DMMTT while
continuing to hold the EXP. MODE button. Once you see all five EXP. MODE LEDs
light up solid, you may release the button. The factory settings have been
restored.
