You've been cricketed!

Someone hid this little gadget to chirp, buzz and play sounds at random. Nothing is broken.

To quiet it

Plug it into a USB wall charger and leave it there.

Play it forward

  1. Charge

    Plug it into a standard 5 V USB-A charger or computer port. Red light: charging. Green: full. A new Cricket arrives asleep; this wakes it.

  2. Set it (optional)

    Plug in and pull out quickly, pausing about half a second each time, then leave it plugged in. The blue light blinks the new setting.

  3. Hide it

    Unplug it and hide it. It starts about an hour later, then plays at random around the gap you chose.

2 plugs: next sound

3 plugs: next timing

4 plugs: off

Good to know

USB
Power only. The data wires are not connected, so it cannot store files and a computer does not see it.
Battery
3.7 V, 100 mAh rechargeable lithium-polymer. When it runs low, the Cricket goes quiet until charged.
Cricket sounds
Chirp faster when warm and stay silent below 55 °F (13 °C).
Lights
It never lights up while playing a sound.
Hardware
Cricket 008, piezo speaker and vibration motor, no buttons.

Troubleshooting

No blinking after setting it
Go a little slower, finish within 10 seconds, and leave it plugged in after the last plug.
Wrong number of blinks
Do it again; each round moves one setting forward.
It never makes a sound
Plug it in once to wake it, charge it, and keep it somewhere above 55 °F if it is on a cricket sound.
No light when plugged in
Try another charger or port. If there is still nothing, contact us.

Safety

  • Lithium battery: do not crush, open or heat it, or leave it in a hot car. Unplug and stop using it if it gets hot, swells or smells.
  • Charge only from a standard 5 V USB-A charger or port.
  • Not a toy. Keep it away from young children and pets.
  • Prank kindly: do not hide it where it could be mistaken for a real alarm.
  • Recycle it at a battery drop-off, not in household trash.
