Telit TRIZIUM Product Description

80264ST10007a Rev. 4– 09/09/04

Note: The phone functionality remains always FULL.

Write command

AT+CFUN=<fun>

Enables/disables the power saving function.

If enabled it reduces the power consumption during the idle time, thus allowing a

longer standby time with a given battery capacity.

Parameters:

<fun>: is the power saving function mode

1 - Mobile full functionality with power saving disabled (default)

5 - Mobile full functionality with power saving enabled

Note: To place the telephone in power saving mode, set the <fun> parameter at value

= 5 and the line DTR (RS232) must be set to OFF. Once in power saving, the CTS

line switch to the OFF status to signal that the telephone is really in power saving

condition.

During the power saving condition, before sending any AT command on the serial

line, the DTR must be enabled and it must be waited for the CTS (RS232) line to go

in ON status.

Until the DTR line is ON, the telephone will not return back in the power saving

condition.

Note2: The power saving function does not affect the network behavior

of the TRIZIUM, even during the power save condition the module

remains registered on the network and reachable for incoming calls or

SMS. If a call incomes during the power save, then the module will

wake up and proceed normally with the unsolicited incoming call code
