Out-of-the-Box Setup
Ensure the QT-5100A Module has a sufficient charge level by immediately inserting the micro USB
charger.
Note:
The QT-5100A Module should only be charged with the supplied charger and attached Ferrite clamp on
the AC Cord. Failure to use the suppled charger could cause damage the unit or result in violation of the
FCC certification.
Using the Reset Key
Occasionally the QT-5100A has an issue where the unit may occasionally need to be reset after being
connected to a charger. The Reset Key is a small male USB device with a yellow shrink wrap to identify
it.
Use this only if the transmitter becomes unresponsive. The transmitter has 2 microprocessors and
occasionally one may become locked. The Reset Key (which is typically attached to the cable of the
charger) should be inserted into the charge port, held for 1 second, and then removed.
After the Reset Key is removed, the Status LED will blink green 3 times.
There are 2 LED indicators on the QT-5100A Module, Status and Charge.
Charge LED Color
When connected to a charger, the color of the Charge LED will indicate the progress of the charging
cycle. The LED is located on the front of the TX.
Note: After the LED changes from Amber to Green, it is recommended it be charged for 15
more minutes while the trickle charge completes.
GREEN
– The battery is charged and ready for use.
AMBER
– The battery level low, but can be used for short term use, such as setup or quick
audio tests.
RED
– The battery level is unusable and must be charged.
