Security code

The cordless telephone handset and base unit have individual security codes. If they are not the same, they cannot link mutually.
If the handset of your neighbor´s cordless telephone can link with the base unit of your cordless telephone, your neighbor´s
telephone bill may be charged to yours. There are mainly 2 types of methods as shown below.
Random ID code method
As shown in Fig.D., while the handset is on the base unit being charges, the security code from the base unit is automatically and
randomly sent to the handset via the control terminal in the charge terminals. Furthermore, if another handset is placedon the
charger of the base unit, a security code is written from the base unit and the handset will be available for use. The security code
written from the base unit is randomly selected from thousands of codes and the same code cannot be selected even if neighbor´s
cordless telephone is the same model.
