We offer a full upgrade service. We upgrade the firmware, the radio hardware and battery. We recommend replacing the battery approximately every 6 years, or when you start to notice they need charging more frequently.

There have been significant changes to the systems, since they were originally introduced in 2005. Older systems can be completely upgraded to the latest 3rd Generation specification that support Digital Channel Separation, with better longer lasting battery packs for better performance.

All you have to do is to post the handsets back and we will do the rest.
