7. PIC CONTROLLER SECURITY CODE
To add extra security to the product in shipment, and to help protect code
security a security code lock feature is built into the PIC Controller. This
helps to ensure that the product can only be used by the intended
recipient who purchased the product either direct or from an authorised
distributor or reseller.
During the first 45 days of product use, the clock may stop displaying the
time and display a 6 digit security code. This is a self-generated true
random number. If your clock displays the security code, please write
down the number carefully, switch off power to the clock and contact the
seller of your clock for the unlock code and unlock procedure.
Do not attempt to unlock or change any settings yourself, as doing so will
more than likely make the PIC permanently unusable.
