It has a simple user interface with a rotary encoder with a push button and LED’s.
The device has an integrated FM radio transmitter and a detachable SMA antenna
which connects to the RF OUT jack.
It has an integrated rechargeable Lithium-Ion battery.
Guitar or other suitable instrument is plugged in the AUDIO IN jack.
AUX IN jack is intended for connecting a line level audio source like a computer,
MP3 player or similar or a mobile phone.
AUDIO OUT jack is a standard guitar level output that can be used for daisy
chaining to other effects processors or for a guitar amplifier.
AUX OUT jack can be used for driving headphones or as a stereo line level audio
output for stereos and HiFi systems.
To charge the device, connect a suitable power source with voltages from 5 to 9
volts using a 2.1mm barrel plug with centre positive pin to the 5-9VDC jack.
The device comes with the battery discharged so it is first necessary to charge it.

3. Navigating the menu
To change the selection, just press the rotary encoder button briefly and the LED
will change its position. The LED changes its position in an anti-clockwise manner.
When the LED is on the selected feature, you can turn the rotary knob to change
the value.
Every time the rotary knob is turned and the value changes, the selected LED
blinks red colour briefly, signaling the value has changed. If the value has
reached its end position, the LED blinks red colour longer singalising the value
cannot be changed any further in that direction.
Some settings are not changeable in bypass mode to prevent them from
accidental change. Those are IN VOL., DISTORTION, and FILTER.
