BT Toggle option in BT Config menu is enabled. It normally takes 3 seconds to connect and 1 second to
disconnect.
This is a very useful feature for iPhone and iPad application. User can enable and disable iPhone and iPad
soft key instantly using this BT Toggle option.
Up key shows Bluetooth connection status and Down key shows time if KDC is connected using SPP profile.

4.2 Auto Connect

This feature allows the KDC to connect automatically to the host device when the KDC is powered on.
IMPORTANT: Until the host device and KDC have been fully tested, it is strongly recommended that this
feature be set to Disable because a host device that does not support this feature can cause problems such
as power loss or upload delays.
[Note] KDC tries to connect automatically to the host 10 times during two minutes if Bluetooth power is ON,
Bluetooth is disconnected, Auto Connect is enabled and system Sleep Timeout is set to 5 seconds

4.3 Auto Power On

The Auto Power On option allows the KDC to automatically power on Bluetooth when the SCAN
button is depressed. The default setting is Disabled. NOTE: The host may have to open the COM port
before reconnecting with the KDC. Power on time determines the scan button pressing time to activate auto
power on feature.
