Procab batteries can be drained by the very circuitry we put in to save them. By removing one resistor and re-orienting another you can considerably lengthen the battery life. This fix will solve the problem of the missing clock (replaced by the text “LESS 1.0”) in the upper right on the ProCab LCD display. The resistors are in the low voltage detection circuit of the radio board. They are not needed for normal operation of the cab.
