Modular ICS Companion Installer Guide

The following sections describe some basic troubleshooting 
techniques to try with a malfunctioning portable telephone or 
base station.

1. Verify that the portable is compatible with the software 

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 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.

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.
