Operation Instruction
When a 12VDC power supply is provided, the red indicator is on. After
connecting to the Headphones, the orange indicator lights up.
DIP Switch Settings
DIP switch settings with selection (switch in power-off state):
- General user Settings: 0000
- Exhibition (Store Setup 1): 1000
- Exhibition (Store Setup 2): 0100
- Exhibition (Store Setup 3): 0010
Note: In general sales, the shipment must be set at 0000.
Power/Signal Connection Connector
The connector uses S9B-PH-SM4-TB produced by JST in Japan. The pin
configuration is as follows. Switching between I2S and analog inputs is
determined automatically with 3 pins (3PIN HI=ANALOG INPUT/LOW=I2S INPUT).
Check Content During Manufacturing
After the final appearance inspection, packaging is carried out.
When the Baseboard is mounted on the piano, ensure ESD measures are
implemented to prevent electrostatic breakdown.

After final appearance inspection, packaging is carried out.
When the Base board is mounted on the piano
WH-L1 BASE does not have a plastic shell, and the baseboard and components are
exposed, so it is very easy to electrostatic breakdown when electrostatic
discharge flies directly to IC and other places. When installing to the piano,
the worker handling the substrate should ensure that ESD measures are
implemented.
Wireless stability
Since it is wireless communication, it is inevitable that communication will
be interrupted due to interference. In addition, the 2.4GHz band is used by
devices as diverse as microwave ovens, Wi-Fi, Bluetooth, codeless phones, and
more. In the event of interference, only keep your distance from those
devices.
FCC STATEMENT
- This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference,and
- This device must accept any interference received, including interference that may cause undesired operation.
- Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
IC warning
This device contains licence-exempt transmitter(s)/receiver(s) that comply
with Innovation,
Science and Economic Development Canada’s license-exempt RSS(s). Operation is
subject to the following two conditions:
- This device may not cause interference; and
- This device must accept any interference, including interference that may cause undesired operation of the device.
FCC/ IC Radiation Exposure Statement
This equipment complies with FCC and IC radiation exposure limits set forth
for an uncontrolled environment. This equipment should be installed and
operated with minimum distance 20cm between the radiator & your body
