Recommended procedure:
Step Action
1 Read the parameter descriptions in Chapter 9 "Term definition", page 65.
2 Enter the desired settings/values in the right-hand column ! of the following tables.
3 Individually select and edit the parameters in turn.
This is the only way to ensure parameter entry within the factory default key timeout of 40 s.
After the timeout, the receiver automatically returns to the normal display.
The selections/settings that were performed before this point remain unchanged.
CAUTION!
Following each parameter change, wait at least 15 s before switching the receiver off as oth-
erwise the change will not have been saved.
This takes place automatically in the background. Premature deactivation results in a config-
uration data checksum error at the next switch-on.
Bit 0 of the Error parameter is set, the upper LED flashes red as a result of the collective
alarm, and the parameters are changed to the factory settings.
