The Chronodot is a “real-time clock” (RTC) module
with precision quartz timing and battery backup.
Important note:
Do not set the battery on any conductive surface, or it
will drain in a matter of minutes. (Examples: Black conductive foam,
silver anti-static bags, steel countertop, etc.)
Similarly, once the battery is installed on the module, do not set the
module on a conductive surface.

RTC module
Slide the battery into the battery holder on the Chronodot, noting
the polarity: “+” side on the battery towards the “+” side on the
holder.
Install the Chronodot in the headers at location M1 on the circuit
board, labeled “Opt. RTC.” Make sure that all eight pins line up
correctly into the sockets, and that the text on the Chronodot is
right-side up (i.e., oriented the same way as the text on the Alpha
Clock Five circuit board).
If you have an older (pre-2.0) version of the Chronodot, where the
battery and/or headers need to be soldered in place, please contact
Evil Mad Scientist Laboratories for soldering instructions.
