Think Outside Sierra Keyboard - Manual (Page 12)

POWER EFFICIENT MODES
1. The Advanced tab allows access to different
power efficiency modes.
2. The Stowaway Sierra keyboard is designed to
operate in Power Efficient Mode in compliance
with the Bluetooth specification. However, some
mobile devices have difficulty operating
effectively with Power Efficient Mode set to ON.
The default setting is Auto, this allows the
keyboard driver to determine whether to use
Power Efficient mode or not. If the driver detects
a mobile device which may work incorrectly in
Power Efficient mode, it will turn it OFF
automatically. You should turn OFF Power
Efficient mode manually if you experience
problems such as:
¾ Inability to Scan for other Bluetooth devices.
¾ Inability to Connect to other Bluetooth devices.
¾ Inability to Discover the mobile device and connect to it from another
Bluetooth host.
NOTE: Turning off Power Efficient mode will shorten the battery life of your
Bluetooth devices.
Power Efficient mode may be turned ON manually to extend battery life if
the mobile device fully supports it or only one Bluetooth peripheral is used at
a time.
