techniques to try with a malfunctioning portable telephone or
base station.
Problems with a portable telephone

version.
2. Verify that the portable is ON and that the battery is not
low, by checking the power indicator on the portable.
3. If no dial tone is present:
a. Verify that the dialtone is available from the ICS.
b. The portable may not be registered. Try to register the
portable refer to the Modular ICS 5.0 Companion System
Coordinator Guide.
4. Check that the portable is using the correct registration
slot.
5. Verify that the portable has been assigned the correct
internal number by calling it from another telephone.
Problems with a base station
1. Verify that the green light is ON.
2. Verify that the red light is not solid.
A solid red light indicates that both radios on the
Companion base station are busy, that the ICS is
downloading data to the base stations, or that one or both
radios have not been assigned to a cell.
