There is a STARTUP demo project for the HMC models in the
MAPware-7000/Projects folder (C:MapleSystemsMAPware-7000Projects) that can
be used to set the Real-Time Clock (RTC) in the HMC.

Open the “HMCxxxxA-M STARTUP.mpl” demo project for your
particular model and download it to the HMC. Tap the startup screen to go to
the next screen, then tap the “Set RTC” button to pop up the “Set Real-Time
Clock” window.

You can use the “Import Screen” option in MAPware-7000
(Screen menu > Import Screen) to copy the “SetRTC” popup screen from the
demo project into your own project, if desired.
