7.3.7 RMA1215 replacement
PREPARATIONS:
Power down system. Remove old unit. Compare the version numbers of the removable RMS
EPROM on the board. Make sure the new unit contains the same or newer EPROM software
version.
ADJUSTMENT:
• Use RMM software to upload configuration to RMA1215.
• The following settings are not stored in the configuration file and must be manually
updated: ILS Date/time, Modem configuration, User configuration, Lamp mappings and
Medium storage sample interval.
• If the version number of the RMS EPROM is lower than 13, it is necessary to upload config-
uration to monitor 1, 2 and standby monitor if present. Note that if this is done it is also nec-
essary to perform a monitor limits test as described in chapter 6.
CHECK:
Monitor Make sure the ILS is operating in normal state (transmitters on) and check that
all parameters are normal.
Maintenance: Check the maintenance parameters for the RMA1215 unit.
7.3.8 LF1223 replacement
PREPARATIONS:
Power down system. Remove old unit and place the new unit on an extender board.
ADJUSTMENT:
Turn on transmitters. It is important to use RMM software to upload LF1223-configuration to
ILS. When the LF-configuration has been correctly uploaded, only minor adjustments should
be necessary. (Follow the procedure in chapter to re-adjust both/all transmitters.)
CHECK:
Monitor: Make sure the ILS is operating in normal state (transmitters on) and check that
all parameters are normal.
Maintenance: Check the maintenance parameters for the replaced LF1223 board.
Transmitters: Check waveforms as described in Technical Manual, chapter 7 for all transmit-
ters.

PREPARATIONS:
Remove old unit and mount new unit in the cabinet. Make a note of all attenuator and phaser
settings on the old unit.
ADJUSTMENT:
Connect all cables and dummyloads to the same inputs and outputs of the new COA 1207.
Set all phasers and attenuators in the same position as on the replaced unit.
CHECK:
Follow adjustment procedures described in Engineering and Comissioning Handbook to verify
