3.0 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.
3.2 Interface Description
See in appendix

are chosen to give the worst case condition. No load capacitors
shall be used.
2. The PSU should not undershoot or overshoot beyond the
regulation limits (4.85Vmin, 5.25 Vmax)
e. Turn off/on Characteristics
1. All timing are to measured with a 5uF capacitive loading and 12V
DC input voltage.

section 3.3.b. No voltage of opposite polarity shall be
present on any output during turn-on or turn off.
f. Fuse Protection
1. A fuse must be present at the input of the circuit so as to protect
the circuit under any fault condition.
g. Short Circuit
1. A short circuit is defined as less than 0.01 Ohm resistance
between the output terminals. The PSU is submitted to a short
circuit at minimum load
2. The output shall Hiccup or Foldback if any of the outputs are
shorted to the secondary common. No damage shall result.
Output shall recover after the short is removed.
h. Overcurrent:
1. The load is increased on one output from its maximum value to
an estimated over current value in several steps at a rate of 0.1
A/sec. The test is repeated at different input voltages.
2. Overload currents applied to each tested output rail will cause
the output to trip before they reach any point of damage to the
circuit. For testing purposes the overload currents should be
ramped at a minimum rate of 0.1 A/sec starting at full load.
3. The limit during overload condition also applies to any single
fault condition.
