2.2 Installation
The installation of the modem consists of making the physical connections necessary to render the
modem functional with your computer. This includes making the proper serial, phone line, and power
connections. Unless otherwise noted, these instructions apply to all models of the BL series.
2.2.1 Safety Warnings
1 Never install telephone wiring during a lightning storm.
2 Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
3 Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
4 Use caution when installing or modifying telephone lines.
5 Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a
remote risk of electrical shock from lightning.
6 Do not use the telephone to report a gas leak in the vicinity of the leak.
7 Ports which are connecting to other apparatus are defined as SELV. To ensure conformity with
EN 41003, ensure that these ports are only connected to the same type on other apparatus.
