General Information
Ericsson IDSL MODEM
|
The Ericsson IDSL MODEM allows you to use your telephone whilst your
computer is connected to the Internet or another data service. Data transfer
rates of up to 115.2 kb/s can be achieved. You still use your ordinary
telephones in the same way and from the same places as before, and no new
interface boards are needed for your computer. The only new equipment you
have to install is the modem enclosed with this package.

Warnings
and Precautions |
To prevent fire or shock hazard, do not expose this appliance to rain or moisture. To prevent
electric shock or malfunction, do not open the Modem unit or power adapter.
- Never touch the power adapter with wet hands.
- Do not unplug the power adapter by pulling its cord.
- Never replace the power adapter with one that is not approved for use on the
Modem. Use only a genuine IDSL MODEM power adapter to power the Ericsson IDSL MODEM.
- Do not place the IDSL MODEM in direct sunlight. Do not install the IDSL
MODEM near a heater, or on top of or beneath another heat-generating
device, or near a moist place. Placing a telephone on top will be acceptable.
- The IDSL MODEM is designed to operate without local earth. Do not earth the IDSL MODEM.
|
Heating |
The modem and power adapter will become warm while in
use. This is normal, and users should not be concerned.
|
Location of modem |
The modem should be located adjacent to the PC or terminal data
equipment. It is better to have a short RS-232 cable. The Phone circuit can
tolerate reasonably long cable lengths, without service degradation. A
spare mains outlet will be required at this location, for the modem power
adapter.
The modem is dark in colour and must be positioned out of direct
sunlight and other sources of heat to prevent overheating.
