Date and Time Indicator
Keypad Polling
The software polling cycle time is 32 ms. After determining that a key was pressed, the tele-
phone does not poll any other keys until the user releases the pressed key.
Pressing the Plus/Minus Key Simultaneously
A specific feature can be configured in Hicom/HiPath (e.g. volume control) when the plus and
minus keys are pressed at the same time.
3.4 Date and Time Indicator
All optiPoint 500 telephones with displays (economy, basic, standard, advance) have a date/
time indicator.
As indicated in CorNet-TS, the telephone only maintains the clock, while Hicom/HiPath are re-
sponsible for setting the time, activating the telephone to display the time, and controlling the
call duration timer.
