Installation support in GPRS mode
The reception field strength of a CU-P4x can be checked during the install-
lation if the GPRS window is deactivated during the start-up.
The reception field strength is displayed with LEDs. It can also be read out
with .MAP110 and displayed graphically.
The function is deactivated with a GSM call. Once the call has been ended,
the CU reactivates the GPRS window. The function can also be deactivated
with the .MAP110 command "Disable field strength indication".
1.
In the MAP120, select tree element "Start up State of Calling Window"
and choose the option "GPRS Window disabled" to disable the GPRS
mode at startup.
2.
Right click on the tree element "Start up State of Calling Window" and
click on "Send to Device" in the popup menu appearing
.
After the set-
ting has been transferred to the CU, the CU is automatically reset and
starts up in GSM mode.
