Section D. On-Demand FX MODE
The PTT remote pushbutton has a dual purpose. If PTT mode is enabled, when you hold the PTT button down for 1
sec, the mic will open and you can start talking. If VOX mode is enabled, the mic will not open if you hold the PTT
button down. This 1 sec delay allows for other features to be accessed using the PTT button cable with shorter
button presses. It also prevents unwanted PTT triggering.
If you key in multiple short PTT button presses that are < 1 sec apart, the unit will automatically access a sound FX
mode that allows you to play out sounds on demand (and also change some of the unit's sound parameters). That
way, even if you are not using PTT mode, you can still use the remote pushbutton cable to access these added
sounds/features.
The following table outlines what the PTT pushbutton does in FX MODE. Note that a single button press is defined
as a momentary depress and release (< 1sec):

In FX MODE, you can also enable/disable the PTT mode at will so you don’t have to access the unit to change from
VOX to PTT mode while in costume. This is useful if you are in a very noisy environment and want to better control
your voice output by enabling PTT mode on the fly.
PTT presses of 4-6 access music tracks. Again these can be stereo or mono wav files with 44.1kHz sample rate and
16 bit sample depth (standard CD). These can be music or sound fx tracks, depending on what you prefer.
NOTE: If you are playing out a long music track, you can stop the playback at any time if you press and release the
PTT button 1x.
ACCESSING THE SD CARD
The microSD card is found under the interface board on the 2nd card. It is a friction fit connector. You can remove
the SD card with some needlenose pliers if you want to change any of the sound files.
