Overview 5
Direct connection
The MD300 can be plugged directly into a USB port as shown below. This configuration offers the
best portability.
Note:
To avoid damage to the MD300 or your laptop’s USB port, remove the MD300 before placing
your laptop into a carrying case.
Caution!
Different laptops have different USB port configurations that may conflict with operation. Use
the included extension cable if:
• The USB ports are close together and the modem covers an adjacent port that is needed.
• The modem can not be plugged in directly, e.g., the USB port is recessed and the USB
connector on the modem can not reach.
• The USB port is in a position where physical pressure is put on the connector as shown
below.
Extension Cable
The extension cable provided is specially designed to work with your MD300. This is a high quality
USB cable that is capable of delivering high current to the MD300 when necessary.
Note:
Do not use standard USB cables between your MD300 and a USB port.
The extension cable has two USB plugs. Plug A carries both data and power and plug B carries power
only.
