Introduction

In case the handset gets out of range of the basestation, it will present "base search" in the display.
The handset is getting asynchronous. The base search procedure is startet only then.

In order to reduce power consumption there is an algorithm implemented preventing the handset from unsuccessfully
repeating the base search over and over again in case no base is available. So the period of time before a base search
is started  is increased step by step from some seconds till it reaches 40 minutes.

Multiple basestation-registration
In case the handset is registered to multiple basestation and is set to "best base" (not E49H!), and the handset is carried to another site/town, the search procedure can be started again by pressing the send key.
