Description
To prevent personal injury and/or damage to property, be sure to observe the following safety precautions.
The following symbols classify and describe the level of hazard and injury caused when this unit is
operated or handled improperly.
This notice means that misuse could result in
injury or damage to property.
The following types of symbols are used to classify and describe the type of instructions to be
observed.
This symbol is used to alert users to a specific operating procedure that must be followed in
order to operate the unit safely.
• The software contained in the TRS and ARS features to allow user access to the network must be
upgraded to recognize newly established network area codes and exchange codes as they are placed
into service. Failure to upgrade the on-premise PBXs or peripheral equipment to recognize the new codes
as they are established will restrict the customer and users of the PBX from gaining access to the network
and to these codes.
KEEP THE SOFTWARE UP TO DATE WITH THE LATEST DATA.
• There is a risk that fraudulent telephone calls will be made in the following cases:
– A third party discovers a personal identification number (PIN) (verification code PIN or extension PIN)
of the PBX.
– Using the Trunk-to-Trunk Call feature of DISA.
The cost of such calls will be billed to the owner/renter of the PBX. To protect the PBX from this kind of
fraudulent use, we strongly recommend:
a. Keeping PINs secret.
b. Selecting complex, random PINs that cannot be easily guessed.
c. Changing PINs regularly.
• To the Administrator or Installer regarding account passwords
1. Please provide all system passwords to the customer.
2. To avoid unauthorized access and possible abuse of the PBX, keep the passwords secret, and
inform the customer of the importance of the passwords, and the possible dangers if they become
known to others.
