Quick Start Guide: Plantronics 1542P Wireless Headset

Model 1542P

Getting Started

Plug the power adapter into the power jack on the back of the base unit and then into a working power outlet. The Power On/Subscription LED will be solid white.
Place the 1542P headset into the charging cradle. The charging LED on the base will flash green while charging and turn solid green when the headset is fully charged. Charge for at least 20 minutes before first use; a full charge takes three hours.
Connect the RJ-45 end of the 801-432 cable to the port labeled "Telephone" on the 1542P base unit. Connect the 2.5mm cable end to the port labeled "Headset" on the 1500A counter station. On the 1500A, select the Privacy key to route audio to the 1542P headset.
The 1542P headset and base are pre-subscribed (paired) and ready for use after charging.
