System Features
On original power-up, the 556T will display a default setting of
12:00 AM, Friday, 01/01/99. No activations will be programmed
and the default temperature scale will be Fahrenheit.
When the ignition is on, the 556T LCD displays the time, date and
temperature. This is the unit's standard operating mode. The unit's
LCD display automatically shuts off whenever the ignition is
turned off. When the ignition is off and any button is pressed, the
LCD will turn on in standard operating mode and display all indi-
cators for 10 seconds. The 10-second timer will reset if another
button is pressed during this time period.
The 556T also features LCD illumination whenever the vehicle’s
parking lights are turned on. The unit will not be turned on, but
rather the LCD will light so that the unit can be easily located if
the surrounding environment is dark.
The 556T will display the current temperature inside the vehicle.
You may select for the temperature to display in either Fahrenheit
or Celsius. While the unit is in standard operating mode, simply
press
to toggle between and select the Fahrenheit (F) or
Celsius (C) setting.
