The period is easily adjusted by varying Rf. R3 ensures
that the circuit will start on a single rail by forcing A1’s
output to the positive rail. R4’s value is not critical but
should be a factor of 10 greater than the parallel combi-
nation of R and R .

The CMV7106 can source output currents in excess of
50mA sufficient to drive several LED lamps while only
drawing 300µA of supply current maximizing battery life.
