Nera WorldPhone · TPU · Portable / Provident / Marine / Voyager · ©2000. Preservation notes for the original Nera WorldPhone Portable, Provident, Marine and Voyager family, not WorldPro 1000/1010. The manual shows copyright 2000; its printed revision is not established. Historical instructions do not establish current service availability or authorization to transmit.
How it connects
Identify the existing Telephone Unit (TPU), antenna configuration and power-supply arrangement. Marine/Voyager have a separate supply to distinguish from the TPU; do not transfer Portable/Provident assumptions. Record the exact existing message, including Not available or Subscriber busy. A busy called party, uncommissioned service and an unsuccessful satellite search are different findings. Do not move the antenna, change cables or make test calls. Phone PIN and the SIM’s PUK are different controls; do not guess codes or reset ownership credentials. Record existing FAX/data-port assignments and the PC/TPU serial rate privately from available records. Local port or rate mismatch differs from network commissioning. Do not reconfigure ports, adjust oscillator compensation, reset or update firmware to test this legacy equipment.
