Radio Controlled PC Clock

The decoded time information (time and date) are displayed on an LCD screen on the front of the unit. Additionally the screen shows the strength of reception of the radio signal, which can be used to align the device during the initial set up to optimise reception.

The AC-500 has a serial interface and is supplied with software to synchronise the internal time and date of a single connected computer. The software will automatically update the time and date on your computer to precise atomic time and date immediately after starting up the computer.

This radio controlled clock for PC may be desk/table or wall mounted.
