Some models of the ThinkPad R61 15.4-inch widescreen computer do not have the Modem Daughter Card slot. Instead, the modem function is integrated in the system board.

If your computer is the ThinkPad R61e model, it does not have the Modem Daughter Card slot. Instead, the modem function is integrated in the system board.

Attention: During electrical storms, do not connect the cable to or disconnect it from the telephone outlet on the wall.

Electric current from power, telephone, and communication cables is hazardous. To avoid shock hazard, disconnect the cables before opening the cover of this slot.
