The reason must be a total loss of power. The delay is caused by the boot up sequence when it sets up the quartz oscillator and waits for it to stabilize. In normal operation this step is not needed because the oscillator keeps running even in deep sleep mode.

Thanks, again Marcus. After I replaced the coin cells and reset date & time the power-on delay has vaporized. whoohoo

Its nice to understand what's going on, and its nice to have it corrected too. The lesson in the last couple of power posts is that these units draw so little current (operate at such low mW normally) that the voltage drop read by the 'BATT' function really can't be taken as a valid readout of the unit's ability to function under load with that set of coin cells. In other words, the real voltage must be considered under load only.

Kind regards,
