Electrical Specifications
This product is a standard BT handsfree visor product with a few additional features.
3.1 General Description
Firmware is to be written to follow requirements of interaction spec with the smarts to store 3
individual presets for each paired phone.
For example, PhoneA presets could be different from PhoneB. The firmware will be smart
enough to remember the BT Phone ID and allocate the separate memory location for presets for
that phone. Therefore, there are actually 9 presets stored in the device.
Whenever a BT phone with an ID already listed in the device, it is moved to the top of the list and
the corresponded presets are loaded. When a phone ID not listed in the device is paired, the
memory location for the one on the bottom of the list will be used overwriting the old ID and
clearing all presets while moving the phone ID to the top of the list.
