Operation
The DuraTime clock is based on super bright LED technology coupled with a very capable
microprocessor. The DuraTime microprocessor is able to store the user’s configuration in
duplicate. If the configuration becomes corrupt by someone configuring the display incorrectly, the
original customer configuration can be instantly restored. The Real Time Clock includes a high
accuracy temperature controlled oscillator as the standard time base and is accurate to a few seconds
per year without external synchronization. For absolute accuracy, the clock receives time updates
from one or more DuraTime master clocks.
Real Time Operation
There is normally no configuration required to connect the DuraTime digital clock to the wireless
network. Simply apply power to the clock within radio range of an active DuraTime network and
the clock will receive and update the display every second.
The Mega Real Time Clock employs a clock circuit with battery backup. The clock circuit will
maintain time for about ten years without power. When you receive your new clock and apply
power, you will see the clock already running. To manually change the time, simply press and hold
either the Up or Down buttons. The time will increment or decrement faster and faster as the
buttons are held. If the clock is within range of a DuraTime master clock, the clock will change to
the master clock time within a second or two.
