Abstract
An adapter for mounting a portable telephone on a vehicle allows either one of a simple handset and a multi-function handset to be used therewith as desired. The adapter does not need a power switch and associated circuitry and, therefore, reduces the overall weight and size of a portable telephone system. When a multi-function handset is used with the adapter, the adapter is switched on and off by a power switch which is provided on the handset. When a simple handset is used with the adapter, the adapter is switched on and off by an ignition switch which is provided on the vehicle. Further, the adapter promotes easy and convenient use of a handset because it automatically adapts itself to both of a multi-function handset and a simple handset.
