Question about GPX D516 Clock Radio
I brought the clock into India and used a voltage converter. However, the mains frequency is 50 Hz and the clock runs slow. What can I do? Is it possible to change the clock locally without touching the IC?
Open the case and look at the clock ic. find the datasheet on the internet. this usually involves placing a jumper to ground for 50Hz operation and opening a jumper for 60 Hz operation.

Considering a 9VDC battery keeps the clock alive when power is disconnected, I would guess the clock time is independent of line current frequency. Does anyone actually use motorized clock works anymore?
