Fellowes Penguin User Manual page 8

• If using wireless, make sure your Penguin's dongle (micro receiver) is firmly
plugged in to your computer's USB port.
• If using wireless, try unplugging the Penguin dongle (micro receiver), then
plugging it back in again.
• If using Bluetooth, on your PC, remove Bluetooth item (Penguin Mouse)
and re-add Bluetooth device again.
• If using wireless, try holding the Penguin close to the sensor for 30
seconds whilst intermittently clicking the top button – it sometimes takes
this to get the dongle to recognise the hardware.
• If using wireless, try using a different USB port to connect your Penguin.
• If possible plug it directly into the computer, i.e. not through any monitors/
keyboards/hubs etc.
• If using wireless, remove the USB Dongle and turn 'OFF' the Penguin
switch. Reboot your computer. Now re-insert USB dongle, wait 10/15
seconds and turn Penguin switch back 'ON' - in 'DOWN' (GREEN) position.
• Although your Penguin is plug & play, make sure your computer is up to
date with the latest drivers / operating software for pointing devices
• Check that the sensor on the underside of the Penguin isn't covered and
has a clear line of sight to the surface below. Also check that your Penguin
has not been dropped which could dislodge the laser
• Try using the Penguin on a mouse mat / unreflective surface
• Make sure the charging cable is firmly attached into the USB port of your
computer and the USB-C end is firmly pushed into the front of the Penguin.
The 'P' Logo should light an orange color. Recharge directly via a USB port
on your computer NOT via a multi-USB hub.
• Try your Penguin mouse on a different PC/laptop to check if the issue is
still present.
