Confidential / Draft - Do not copy

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

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

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

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

- 2.7 seconds. See also

AT+CFUN

for the timing of CTS.
