Configuration of Energy Conservation Modes and Real-
Time Clock
The following sections show an overview of the extended functions of the INSYS
GSM small 2.0 in view of different energy conservation modes. Please refer to the
AT command set for the Cinterion TC63i for more detailed information and the AT
commands used for this.
Moreover, the INSYS GSM small 2.0 provides an integrated real-time clock (RTC,
no buffer), which can also be used in connection with the sleep and PowerDown
modes.

Time / Date
The real-time clock (RTC) of the INSYS GSM small 2.0 has no buffer and will be re-
set to
"02/01/01,00:00:00"
if the power supply is disconnected. The RTC takes
2 seconds for initialisation after a restart (reset or power-up). Therefore, we rec-
ommend to wait 2 seconds for the message
^SYSSTART
before executing the com-
mands
AT+CCLK
and
AT+CALA
.
Configuration with HSComm
A configuration of this function using the HSComm software is not pos-
sible.
Configuration with AT commands
In order to configure date and time, use the
