8.8 Replacement of the control module SM 2009

The control module is a Printed Circuit Board situated on the left-hand side of the Repeater.

Disconnect the DC cable from power supply.

Disconnect the flat cable.

Remove the Tyrap which is fixed to the control module.

Disconnect the RS232 cable from the modem if the Repeater is equipped with a modem.

Dismount the battery backup board, if the battery backup module is installed.

Take off the whole control module completely with mounting plate by unscrewing four tallow
drop screws M4.

For mounting proceed in reverse order.

Position of the control module in the Repeater is illustrated in REFthe following figure.
