Charging Both the Receiver (WL-20 / WL-20L)

and Transmitter (WL-T)

1. Connect the included USB cable and a

commercially available USB AC adaptor (5 V/0.5 A

or higher) to the receiver’s DC IN 5 V port.

2. Insert the transmitter into the TRANSMITTER jack

so that the transmitter also charges.

Charging is completed.

* We recommend that you disconnect the transmitter

after charging is completed. If you leave it

connected, a small amount of power is used from

the battery, and the indicator blinks green once

every eight seconds.

* If you have not used the transmitter for a long time,

one charge might not be sucient. Disconnect and

reconnect the transmitter to complete charging.

Charging only the transmitter

Connect the included USB cable and a

commercially available USB AC adaptor

(5 V/0.5 A or higher) to the DC IN 5 V

port.

* When charging from the DC IN 5 V

port, the wireless connection does

not operate.

Making Wireless Settings

(Auto Wireless Connection)

* Execute the following operation before you play your guitar (musical

instrument). In particular when you’re playing live or in a session, the

wireless conditions might change between the rehearsal and the

actual event, so you should execute the following operation once

again before the actual event.

1. Insert the transmitter into the TRANSMITTER

jack.

This blinks orange while Auto

Wireless Connection settings are

being made. The process completes

in approximately 10 seconds.

When the orange blinking stops,

remove the transmitter.

For stable wireless communication

If audio dropouts occur, it might be that the local state of the wireless

spectrum has changed. Execute the Auto Wireless Connection

operation once again.

Since the WL-20 / WL-20L uses a 2.4 GHz wireless system, we

recommend that you place the receiver at least three meters away

from a Wi-Fi router or other wireless device.

Using a microwave oven might also cause audio dropouts due to

wireless interference.

Using multiple wireless systems together

To prevent confusion between the wireless systems, perform the

following steps.

1. Power-o the BOSS wireless systems.

2. Power-on any wireless systems not made by BOSS,

and set them up so that there are no problems with

their sound.

DC IN 5 V port

(USB Micro-B type)

3. Insert the transmitter into the receiver’s

TRANSMITTER jack and execute the Auto Wireless

Connection procedure.

4. Plug the transmitter into your guitar (musical

instrument), making the BATTERY indicator light.

Second and subsequent wireless system units made by BOSS

5. Repeat steps 3 and 4.

Performing

When you plug the transmitter into your guitar (musical instrument)

and plug the receiver into your amp or eect unit, the transmitter and

receiver power-on automatically.

* To prevent malfunction and equipment failure, always turn down the

volume, and turn o all the units before making any connections.

POWER/BATTERY indicator

Lit green There is sucient remaining battery capacity.

Blinking green Standby mode.

Lit orange Battery will be exhausted in less than two hours.

Lit red Battery will be exhausted in less than 30

minutes. Please recharge.

Switches to standby mode when silence continues

5When one hour passes without you playing your guitar

(musical instrument), the transmitter enters standby mode

and ends the connection with the receiver. The BATTERY

indicator blinks green.

5 When one hour passes after the connection with the

transmitter has ended, the receiver enters standby mode.

The POWER indicator blinks green.

Note when returning from standby mode

5When you raise the volume of your guitar (musical

instrument) and play it, the transmitter returns from standby

mode in approximately two seconds.

5The receiver must be disconnected and reconnected.

When not using the system for an extended time

Unplug the transmitter and receiver. Standby mode does

consume battery power, although only very slightly.

Turning the Power O

1. Minimize the volume of your guitar (musical

instrument) and of output devices such as the

amp, and then turn o the power.

2. Unplug the transmitter from the guitar (musical

instrument).

3. Unplug the receiver.

Troubleshooting

Problem Items to check/Action

No sound when

you play the

guitar (musical

instrument)

in which the

transmitter is

inserted

Remove and reinsert the transmitter in the

guitar (musical instrument).

Is the receiver too far away from the transmitter?

Alternatively, are there obstructions between

them?

Decrease the distance between the receiver and

the transmitter.

Could you be recharging transmitter from the

DC IN 5 V port?

Disconnect the USB cable when you’re playing.

Is the transmitter’s BATTERY indicator lit?

If it is unlit, recharge the transmitter.

Is the receiver’s RECEIVE indicator lit?

If it is unlit, execute the Auto Wireless

Connection procedure.

The sound

of a dierent

guitar (musical

instrument) is heard

Could there be a dierent receiver or transmitter

nearby?

Execute the Auto Wireless Connection operation

once again.

If this does not solve the problem, it could be

that radio-frequency congestion on the 2.4 GHz

band is causing channels to conict with another

wireless system.

To reduce radio-frequency congestion, turn o

the power of any unused Wi-Fi router, Bluetooth

device, or microwave oven, and then execute the

Auto Wireless Connection operation once again.

The BATTERY

indicator blinks

red

A charging error occurred.

5If the transmitter’s internal temperature rises,

charging might pause.

This occurs in order to protect the

rechargeable lithium-ion battery. When

the internal temperature falls, the BATTERY

indicator changes to be lit orange, and

charging resumes.

5Could the ambient temperature be above

35 °C?

Charging might stop for a while in order to

protect the rechargeable lithium-ion battery.

Use the unit in the recommended ambient

temperature range of 10–30°C.

5If the indicator continues blinking red

even though you are charging in the

recommended temperature range (10–30°C)

Contact your dealer or a Roland customer

service center.

WL-20 / WL-20L

Stable wireless communication with no dropouts (Auto Wireless Connection)

Simply connect the transmitter with the receiver; the receiver scans the local state of the wireless spectrum and automatically chooses the

optimal channel.

Switches to standby mode when silence continues

When one hour passes without you playing your guitar (musical instrument), the transmitter enters standby mode and ends the connection

with the receiver. When one hour passes after the connection with the transmitter has ended, the receiver enters standby mode.
