What to do if Panasonic extensions don't operate during a power failure?
- AAngela HallSep 22, 2025
During a power failure, if extensions connected to specific ports on MSLC16/CSLC16/SLC16 and DHLC8/SLC8 cards don't work, it could be due to a DPT or APT being connected to the extension port, or an incorrect dialling mode. Disconnect the DPT or APT and connect an SLT. Also, set the Tone/Pulse switch to the other position.
