  If you cannot hear a dial tone on your Panasonic Cordless Telephone, first check if the AC adaptor or telephone line cord of the base unit is properly connected. If the connections are correct, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates correctly, contact service personnel to repair the unit. If the working telephone does not operate properly, contact your service provider/telephone company.

  If liquid or moisture has entered your Panasonic Cordless Telephone handset/base unit, disconnect the AC adaptor and telephone line cord from the base unit.

Once completely dry, reconnect the AC adaptor and telephone line cord, reinsert the batteries, and charge fully before use. If it still doesn't work, contact an authorized service center.
