·Check to make sure your COM port setting (see: Options > Application Setup) corresponds with the physical COM

port on your PC.

·Check to make sure the COM port is not configured for another application. Personal Digital Assistant (PDA) soft-

ware or other device applications may be occupying the port at start up. You may

have to exit the occupying software to release the COM port for the Link software.

·Make sure the Link serial cable is securely connected to both the COM port on your PC and the PowerTap comput-

er. Notice that the PowerTap computer should be awake (LCD segments

illuminated) before you attach the PowerTap computer to the Link serial cable. Notice that the screen goes blank

as soon as you make a positive connection with the cable.

·Be sure to "CLEAR ALL" in the ride mode and the interval memory mode in black bodied CPU's after you download

your data or future rides may be lost. A "clr" in any yellow bodied CPU will clear

current ride data as well as interval data.

·To extend battery life after download on any black bodied CPU follow the below sequence (note that any Pro or yel-

low bodied CPU do not require these steps:

1. Remove the CPU from the Link download cradle immediately after the download is completed. Leaving the CPU

on the download cradle will contribute to excessive battery drain.

Just removing the CPU from the download cradle and allowing it to go into the blank LCD sleep mode

does not return it to its normal power-conserving mode -

and you must complete the next two steps.

2. Place the CPU into the bike receiver shoe and wake it up by pressing either button.

3. Turn the rear wheel enough to allow the CPU to receive a valid signal. The rear wheel is only required to turn a

few times, and it is not necessary to ride the bike.

IImmppoorrttaanntt::

The CPU must receive a valid signal from the hub as indicated in the upper left-hand corner of the LCD

display.

·Once you have completed all three steps noted above, the CPU will be in its normal power-conserving mode and

can be removed from the bike receiver shoe.
