Internal Clock/Calendar - Grecom PSR-800 Owner's Manual

Internal Clock/Calendar

Your PSR-800 includes a real time clock/calendar that is used to
correctly date and time stamp recorded audio files.
The first time you power on your PSR-800, you will be prompted
to set the time and date.
If batteries are allowed to fully discharge, or if they are removed
from the PSR-800 for more than a few minutes, the date and
time will need to be set again.
You can also set the date and time over the USB connection
using the PSR-800 PC application, or using the Set Clock
function in the Main Menu.
