Batteries for the sender
Open the battery cover on the back of the sender to insert two protected 18650 rechargeable
batteries with button top (not included). It is recommended to use 3200 mAh or higher batteries.
Power adapter for the receiver
The receiver can operate with a standard 9V 300 mA power adapter with center negative polarity
(not included). This is the same adapter as used by most guitar effect boxes.
Power switches
Slide the power switch to the right on both the sender and the receiver. The green power LED turns
on and the blue RF LEDs are flashing or solid, depending on the state.
If the blue RF LEDs are flashing then the sender and receiver need to be paired. Press the pair button
on the sender once with a pen or other small pin. When the pairing succeeds, the blue RF LEDs will
turn solid.
Once the blue RF LEDs are solid, then the sender and receiver are connected and ready for use.
A sender remembers when it is paired to a receiver, so next time you turn on the sender
and receiver they will connect automatically and the blue RF LEDs turn solid immediately.
Only use protected 18650 batteries with a button top. Unprotected batteries have no
current protection and may cause a fire in case of a short circuit.
Actually, the receiver accepts any voltage between 5V and 20V DC with center negative
polarity.
Use a dedicated power adapter for the receiver. Daisy chaining the power from other
equipment may cause a hum in your sound.
Remove batteries when sender is not in use.
