c) Disabling Bluetooth
It is possible to totally disable Bluetooth communication if desired.
Typically, there is no need to disable Bluetooth since unauthorised access is protected with
a PIN code, but certain situations may warrant it for an even higher level of security.
There are two options available:
Option #1: Enabled for 30 seconds
This option allows a Bluetooth connection to made within the first 30 seconds after a power-up;
enabling a firmware update to be completed or Bluetooth to be re-enabled. If no Bluetooth
connection is made within the first 30 seconds, then Bluetooth is disabled thereafter.
To disable Bluetooth:
i.
Complete initial Bluetooth pairing and connection using the default PIN code
(000000) or the current PIN code set.
ii.
Access the 'device options' by selecting the 'settings' icon (gear) in the top right
corner, then the 'device options' icon (three vertical dots).
iii. Open the 'Product info' page by selecting 'Product info'.
iv. Beside 'Bluetooth Enabled' select the dropdown arrow to expand the menu, then
select 'Enabled for 30 seconds'.
