Unlock Signal Button

Purpose

Unlock Signal Button (on the right)

Locking a signal prevents a route from being set from the signal. Unlocking signals is done using the LsESpT button.

Operation

Manual lock light (combined signal)

Manual lock light (shunt signal)

To unlock a signal, press the signal button together with LsESpT. The yellow light at the foot of the signal will extinguish. Route setting from the signal will again be possible.

Locking a signal is achieved in much the same way using the Lock Signal Button (LsSpT).
