4. Stowing the Earbuds
When not in use, the PI7 earbuds should be
stored inside the charging case where they will be
recharged ready for future use.
5. Battery Charging
PI7 ships with the case and earbud batteries partially
charged and may be used immediately. For best
practice we recommend fully charging the earbuds
before rst use. Please allow up to 3hours for full
charge.
To charge the PI7 earbuds:
1. Place the PI7 earbuds in the charging case.
2. Close the charging case lid.
To charge the PI7 charging case:
1. Use the supplied USB charging cable and
connect the USB plug to a USB wall charger or
a powered computer USB socket.
2. Then connect the USB-C end to the charging
case USB-C socket.
Note: During charging, the case indicator will
blink green. When fully charged, the indicator
will remain illuminated. The case can be charged
with or without the earbuds being housed inside
the case.
To charge the PI7 case with a wireless charging
station:
1. Place the charging case onto a wireless
charging station.
2. Ensure that the rear of the charging case is on
the charging station (with the case indicator
facing up).
Note: During charging, the case indicator will
blink green. When fully charged, the indicator will
remain illuminated.
5.1 Status Indicator
The status indicator is located on the front of the
case. When the earbuds are placed in the case the
LED provides information about the earbuds. When
the earbuds are removed from the case the LED
provides information on the charging case. See
Diagram 3 for LED states.
5.2 Checking Battery Levels
You can check the case battery level by pressing the
button on the outside of the case once. When both
earbuds are stowed in the case, press the same
button twice to see the earbuds battery level. See
Diagram 4 for button location.
