never been used or not been used for a while to few seconds when the
device is regularly used.
Charging and Switching On
The device has an internal rechargeable battery which must be charged
before use. Before the first use we recommend the device is left on charge
for a minimum of 8 hours.
Your Device can be charged from any USB compatible charging device,
although we recommend you use the provided charger whenever possible.
To charge the unit:
• Connect the charger to a wall outlet
• Attach the USB cable to the charger
• Unscrew the cap from the bottom to reveal the USB port
• Plug the USB cable into the USB port on the bottom of the device
When charging the light on the front of the keypad will be red. The red light
will flash for 5 minutes when the unit has finished charging, and will then go
off.
The estimated charging time to fully charge the device is 7 to 8 hours from
completely discharged.
The device can be used whilst charging, however, the charging cycle will
complete more quickly if the device is deactivated. The device can be used
with a partially charged battery.
Your YB is now ready for use. You can turn it on by pressing and holding the
OK button for 5 seconds.
Sending a basic alert
The alert button is located under the flap at the bottom of the unit. To trigger
an alert, lift the flap and hold down the alert button for 5 seconds. The
screen will display ‘Sending Alert’ and the YB will try to transmit an alert
message.
If you are in an alert situation, ensure that you give your alert the best
possible chance of sending by considering the orientation of the YB. Ensure
it has a good view of the sky, or as good a view as is possible in your
situation. The better the view of the sky, the more likely it is that your alert
will be received.
The alert button will work even if the unit is deactivated.

Hints & Tips
Charging your unit from
empty should take between
6 and 8 hours, depending on
the speed of the charger.
Some chargers will not
provide as much power as
others, and so the unit may
charge more slowly.
When the unit has finished
charging, the light on the front
will flash red for 5 minutes,
and then will go off.
