SLEEP mode is activated (<strong>AT</strong>+CFUN<br />

parameter ≠ 1) while the ME is<br />

registered to the GSM network. Additionally,<br />

PDP context is activated.<br />

Note: When the ME is in Limited Service or IDLE mode with/without PDP context activated, the on/off time ratio<br />

of the LED is always the same, no matter whether or not power saving is enabled. The only difference is that in<br />

SLEEP mode the duration of the on/off periods is a multiple n of the equivalent periods without SLEEP mode.<br />

The multiple n is synchronous to the active state of CTS during SLEEP mode (where CTS is set/reset every 0.9<br />

- 2.7 seconds). See also <strong>AT</strong>+CFUN for the timing of CTS.<br />
