MEopMode/Airplane: Airplane mode upon ME restart
There are two ways to enter Airplane mode upon restart: One is using 

 as described

below. 

Another approach is configuring the ME to restart into Airplane mode at a scheduled time. In this case, use the

 command, set an alarm time and then switch the ME off. When the alarm time is reached the ME

wakes up to Airplane mode, no matter whether 

 was set "on" or "off". 

Parameter 

 is global for all interfaces, non volatile and will not be reset by 

“on“

Causes the ME to enter the Airplane mode each time the ME is restarted or

reset. 

After restart or reset, the URC "

" appears and

parameter 

 is "on". The SIM PIN can be entered using the 

command. This enables the ME to read data from the SIM and give access to

SIM PIN dependent AT commands which are available in Airplane mode, such

as phonebook commands or several SMS commands. To notify the user when

SIM data are accessible it is recommended to activate the "

URC and store its presentation mode to the user profile with 

. 

To return from Airplane mode to Normal mode set the parameter 

 to "off"

as described above. If PIN authentication was already done, the ME will try

now to register to the GSM network. 

“off“

(P)

Airplane mode will not be activated after ME restart or reset. 

Power saving mode 9 timeout
This parameter can be used to query or configure the wake up time for power saving mode 9 (see 

parameter 

=9). The granularity of the timeout value is 100ms (i.e. a value of 10 equal 1 second). The min-

imum timeout value that can be applied is 5, but accuracy is only guaranteed for timeout values greater than 20.

Parameter is global for the ME, volatile and will not be reset by 

.

Allowed radio band(s)
The parameters 

 and 

 allow the subscriber to set and query preferences for selecting fre-

quency bands. 

Before changing 

 ensure that no network activity occurs. The write command cannot be exe-

cuted when making a call, sending or receiving short messages or when the mobile is not registered, but search-

ing for a network. Therefore, to keep track of the module's registration state when changing the band

configuration, it is recommended to activate the URC "

" first (see Section 

). For example,

the URC "

: 2" indicates that the ME is in network search mode. In this mode any attempt to change the

band parameters will be rejected with ERROR. 

Execution of the write command causes the ME to deregister from and re-register to the network, no matter

whether the selected 

 or 

 setting really changes. In this case too, it is useful to have the URC

"

" enabled. 

The status of the SIM PIN authentication remains unchanged, eliminating the need to enter the SIM PIN again

after the change. 

The parameter 

 determines the maximum range of the bands allowed. The value may be one of the single

bands listed below or all valid combinations from the values 1, 2, 4 and 8. Thus, the value range of 

 is

"1".."15". To select or deselect a band calculate the sum of the values of all desired bands and enter the resulting

value. For example, for 1800 MHz (2) and 850 MHz (8) please enter the value (10). 

Parameter
