Items to check/Action
Could a guitar be connected to the INPUT jack? The guitar connected to the INPUT jack takes
priority.
Is the KATANA-AIR EX too far away from the guitar? Alternatively, are there obstructions between
them? Decrease the distance between the KATANA-AIR EX and the guitar.
Could there be a different KATANA-AIR EX unit or transmitter nearby?
Temporarily plug the transmitter into the TRANSMITTER IN jack, and wait for the BATTERY indicator
to stop blinking orange before you use it.
Could the KATANA-AIR EX be operating only on batteries?
The batteries installed in the KATANA-AIR EX have run low. Either replace the batteries or connect
the AC adaptor.
A charging error occurred.
¹ If the transmitter's internal temperature rises, charging might pause.
This occurs in order to protect the lithium-ion battery. When the internal temperature falls, the
BATTERY indicator changes to be lit orange, and charging resumes.
¹ Could the ambient temperature be above 35°C?
Charging might stop for a while in order to protect the lithium-ion battery. Use the unit in the
recommended ambient temperature range of 10°C–30°C.
¹ If the indicator continues blinking red even though you are charging in the recommended
temperature range (10°C–30°C)
Contact your dealer or a Roland customer service center.
