These Operating Instructions describe which functions can be used with the
Hicom 150 H system in version 1.2 with commercially available ISDN telephones.
You may find that some functions you wish to use are not available on your telephone. This
may be due to one of the following reasons:
• The function has not been configured for your telephone - address any questions to
Customer Support.
• Your communication system does not support this function - contact your Siemens
sales representative to upgrade your system.
For the basic operating functions of your telephone please refer to the relevant operating
instructions.
