Basic Operation
The FireFly can be run from the internal battery pack, external 120-240VAC power or external
12VDC power. To operate the unit from the battery pack or external AC, flip the power switch to
the left position. The unit can operate while the battery is being charged, but the time needed to
achieve a full charge may be longer than if the unit was not being used during the charge period.
To operate the unit off of 12VDC external power, flip the switch to the right position. Note that the
FireFly cannot be charged from external DC power.
Note: when the unit is first powered on, it will take 15-20 seconds to initialize.
After the unit is operational, you can set the volume level for whatever audio source you are using
by adjusting the appropriate level control knob on the upper panel of the FireFly. You can use all
four audio inputs simultaneously.
Wireless Microphone operation
The wireless microphone system integrated into the FireFly ships with the handheld transmitter
paired to the receiver inside the unit. To start using the wireless system, you can simply take the
handheld unit out of the storage pouch inside the lid and press the power/mute button until the
green light on the mic is on. To mute the microphone, press the button once. When muted, the
indicator on the handheld transmitter should be red. To shut the microphone off, simply press and
hold the button until the light goes off.
If you need to change the channel that the system is using, you will need to access the micro-
phone receiver settings. First, remove the microphone access panel by undoing the two knurled
knobs. You can now see the programming panel of the unit. Press and release the channel but-
ton. This will scan for an available channel and select that channel. Next, turn on the handheld
unit and remove the battery cover by unscrewing the lower part of the handheld transmitter. Point
the base of the unit towards the microphone receiver and press and hold the sync button on the
receiver. Hold the button until the red lights on the receiver and handheld unit stop flashing. The
receiver ready light should now be lit and the system should be set to operate on the new channel.
Re-attach the battery cover on the handheld unit.
The operational range of the wireless transmitter is approximately 300’.
Battery System
The FireFly has a 5AH NiMH battery which is charged by the integrated battery charger. Depend-
ing on the program material being reproduced by the FireFly, the battery should provide up to four
hours of operational time. If the battery has become fully discharged, it may be necessary to
power the unit off for 5-10 minute to allow the battery pack to recover sufficiently for the battery
charger to optimally recharge it. The battery charger is a smart charger design, meaning that it
can quickly charge the battery pack to full charge within 1-2 hours without harming the cells.
