To prevent unauthorised monitoring, it is recommended the LCS user assign an extension PIN. This PINwill be required when setting LCS (® 2.24.1 Extension Personal Identification Number (PIN)). If the userforgets the PIN, it can be cleared by an extension assigned as the manager.• Each extension can be programmed to either end recording or continue recording the conversation afterthe call is intercepted, through personal programming (LCS Mode Set [After Answering]).• To use the LCS feature on a PS in Wireless XDP Parallel Mode, LCS can only be turned on or off from thewired telephone. In Wireless XDP Parallel Mode, setting LCS on/off from the PS has no effect.(® 5.2.4.5 Wireless XDP Parallel Mode)• A sub extension of a one-numbered extension cannot perform LCS.
