WL-T FAQ
Q: What kind of guitars can the transmitter (WL-T) be used with?
A:
It is installable on general guitars (Stratocaster type, Telecaster type, Les Paul type, SG type, electric acoustic guitars, and the like).
Note, however, that in the case of guitars that have special output specifications, sound might not be produced, or installation might be physically impossible.
Symptoms and their causes for respective different specifications, along with remedies, are highlighted below.
Some guitars equipped with active pickups
Symptom: No sound is produced. Guitar audio includes a thumping sound.
Cause: In the active circuits that guitars have, generally, TRS jack output is wired so that the tip is audio, the sleeve is the ground, and the ring is for the battery ground, but in some cases, there are guitars on which the ring and sleeve wiring is reversed (shown below).
Remedy: Try making the connection shown in remedy A or remedy B. 
Some guitars on which installation is not possible
Symptom: The WL-T cannot be physically installed on the guitar.
Cause: Installation is impossible if the area at the mounting jack lacks enough space for attaching the transmitter (a cylindrical space measuring 18.5 mm in diameter and 5 mm deep).
Remedy: Try making the connection shown in remedy B.
YAMAHA Silent Guitar
Symptom: No sound is produced. The guitar is not powered.
Cause: The electrical wiring has special specifications, and so the no operation is possible without below remedy.
Remedy: Try making the connection shown in remedy A or remedy B in the figures above.
Instruments whose OUTPUT jack is stereo 1/4-inch phone type (TRS 1/4-inch phone type)
Symptom: Only the L-side signal is output.
Cause: The WL-T has monaural specifications, and so only the L-side (tip-side) signal is output.
Remedy: Because of the specifications, no remedy is available.
If remedies A and B do not correct the problem, try repeating the procedure below.

1.Remove the batteries or disconnect the power adapter from the guitar.
2.Attach the jack adapter plug to the transmitter and connect it to the guitar.
2.Attach the jack adapter plug to the transmitter and connect it to the guitar.
Q: The guitar sound contains high-frequency noise.
A:
It could be possible that the noise occurs because the guitar's internal circuitry and battery are too close to the transmitter (WL-T).
As shown in the figure below, make the connection to the guitar using a Mono Patch Cable (1/4" (M) - 1/4" (M)) and a Mono or Stereo Adapter (1/4" (F) - 1/4" (F)).

Q: The series offers ultra-low latency. What is the extent of the latency that occurs?
A:
Latency of 2.3 ms occurs.
Q: Is the transmitter (WL-T) compatible with the KATANA-AIR and the WL series?
A:
The transmitter (WL-T) can be used with the KATANA-AIR, WL-20, WL-20L, and WL-50.
The detection conditions when the transmitter changes to standby mode differ according to the device used.
The respective conditions set automatically when carrying out auto wireless connection are as follows.

- KATANA-AIR: Vibration detection
- WL-20, WL-20L, WL-50: Sound detection
Q: Is the rechargeable lithium-ion battery used in the transmitter replaceable?
A:
Replacement is not possible.
Q: Can the transmitter (WL-T) be used while it is charging?
A:
No, it cannot be used. Use it after charging.
Q: While the transmitter is charging on the dock, can the WL-50 perform wireless communication with another transmitter?
A:
Wireless communication during charging on the dock is not possible.
Q: What are the external dimensions of the WL-20 and WL-20L?
A:
Download and check the WL-20/WL-20L (Receiver) Outline available here.
Q: What are the external dimensions of the transmitter?
A:
Download and check the WL-T (Transmitter) Outline available here.
Q: The sound from another guitar is heard.
A:
Are there another receiver and transmitter or Wi-Fi router nearby?
Make sure the Wi-Fi router and the receiver are at least 3 meters apart.
Also, carry out the Auto Wireless Connection procedure again.
If the symptoms persist, it means that radio-wave congestion is occurring in the 2.4-GHz band, and another wireless system is conflicting with the channel.
To eliminate the radio-wave congestion, turn off the power to any Wi-Fi routers, Bluetooth devices, and microwave ovens not in use, then redo the Auto Wireless Connection procedure.

Q: How can I use multiple wireless systems at the same time?
A:
To prevent interference in the wireless communication, carry out the following procedure.
- Turn off the power to the BOSS wireless systems.
- Turn on the power to any non-BOSS wireless systems, and ensure that sound is played without problem.
- First BOSS wireless system
Turn on the power to the receiver, insert the transmitter, and carry out the Auto Wireless Connection procedure. - Insert the transmitter into the guitar, making the BATTERY indicator light up.
- Second and subsequent BOSS wireless systems
Repeat steps 3 and 4.
Q: The transmitter's BATTERY indicator is flashing in red. What should I do?
A:
A charging error has occurred. First, check the following points.
The transmitter's internal temperature might be elevated.
Charging is sometimes paused to protect the rechargeable lithium-ion battery.
When the internal temperature falls, the BATTERY indicator changes to lighting up steadily in orange, and charging resumes.
Detach the transmitter from the receiver and wait a short while before resuming use.
The ambient temperature might be 35 deg. C or higher.
Charging is sometimes paused to protect the rechargeable lithium-ion battery.
Use in the recommended ambient temperature range of 10 deg. C to 30 deg. C.

Q: The system was left unused for several days with the transmitter connected to the receiver's TRANSMITTER jack, and the battery ran down. Is this a malfunction?
A:
When the transmitter remains connected to the receiver's TRANSMITTER jack, the transmitter and receiver both go into standby mode, and a small amount of battery power is consumed.
When in standby mode, the BATTERY/POWER indicator flashes every 8 seconds.
When the system will be out of use for a lengthy period, we recommend detaching the connections and turning off the power.
