Sony pcv-rz104 User Manual

Many factors influence modem connection speed, including telephone line noise or compatibility with 
telephone equipment (such as fax machines or other modems). If you think your modem is not connecting 
properly to other PC-based modems, fax machines, or your Internet Service Provider, check the following: 

❑

Have your phone company check that your phone line is free from any line noise.

❑

If your problem is fax-related, check that there are no problems with the fax machine you are calling and 
that it is compatible with fax modems.

❑

If you are having a problem connecting with your Internet Service Provider, check that the ISP is not 
experiencing technical problems.

❑

If you have a second phone line available, try connecting the modem to that line.

❑

If using the mouse delivered with your computer, check that it is plugged into the PS/2 mouse port on 
the back of the unit.

❑

PS/2 connections are not ’Plug and Play’ devices, which means that if you connect the PS/2 mouse after 
the system has started, it does not work. Shut down the computer and connect the mouse before 
restarting the system.

❑

Note that the scrolling features work only with programs that use scroll bars. Some programs do not 
support features usually available with the central wheel.

❑

Do not use the mouse on a reflective surface (such as a mirror) or transparent surface (such as glass). 
Some surfaces do not allow the sensor and DSP to function properly because the irregularities are too 
small to be detected. The best surfaces reflect but scatter light; an example is a blank sheet of white 
drawing paper. Otherwise, use a standard mouse pad.
