Modular ICS Companion Installer Guide

To replace a base station, you do not have to power down the 
ICS. When you replace a base station, no portable registration 
information is lost. After a short boot sequence, the base 
station should be functioning normally.

To replace a base station, follow these steps:

1. If the base station is powered locally, unplug the power 

supply from the AC outlet and unplug the power supply 
connector from the base station

2. Remove the cover from the base station mounting bracket.

3. If an external antenna is installed, unplug its coaxial cable 

from the base station.

4. Unplug the teledapt cable from the base station.

5. While holding the base station, to prevent it from falling, 

apply upward pressure to the base station.

6. Lift the base station away from the bracket.

7. Carefully install the new base station onto the bracket.

8. Gently press down to snap it into position.

9. Reconnect the teledapt cable to the base station connector.

10. Reconnect the power supply connector and external 

antenna coaxial cable to the connectors from which they 
were removed.

11. If the base station is powered locally, plug the power 

supply into the AC outlet.

The red light on each base station will flash for about 
15 seconds while powering up. This is normal.
