Technical Update – Optus CEL-FI RS2

Posted on

Cel Fi RS218 Optus 3G Repeater

Technical Update Issues Being Experienced – Optus CEL-FI RS2

Please be advised Optus are currently making changes to their network which may affect your Optus CEL-FI RS2 system. Some of these changes may result but are not limited to the following symptoms: An E1 or E6 error indicator on the LED display, dropouts, weak or no available signal or other unusual behaviour.

Based on the knowledge currently available to Powertec the cause of the disruption to your service appears to be related to frequency changes made to the cell tower, the cell tower ID, or the amplitude of the signal previously available to you.

If you are experiencing any or all of these symptoms please click the link below and follow the firmware upgrade instructions:


Once the upgrade has been completed you should be able to continue using your Optus CEL-FI RS2 system as you did previously. However, in some cases, you may find your Optus CEL-FI RS2 system does not behave the same way as before. This is most likely a result of changes to the Optus network and does not indicate a faulty unit.

Disclaimer: While Powertec does their best to work closely with the Australian mobile carriers we have no control over upgrades or changes to their network and are not liable for disruptions or changes in the performance of your CEL-FI system or mobile device caused by changes made by the mobile operator.
