PowerTap SL 2.4 - Manual (Page 13)

FINDING SENSORS
The PowerTap SL 2.4 hub, sensors and computer are "paired" or "learned" at the factory so that
the system is ready to ride once installed on the bicycle. Learning involves viewing and storing
each device ID into the PowerTap computer. Information on learning can be found in computer
setup 5 section of this owner's manual.
In addition, there is a feature called "Find" that allows the user to search for stored devices in the
event a sensor has lost contact with the PowerTap computer for any reason. To initiate the Find,
hold [Mode] and [Select]. Release when "Find" appears on the bottom of the PowerTap screen
after about 2 seconds. The current watts display will switch to a spinning dial, indicating the
search is in process. When the search is successful, the transmission icon appears in the upper
left corner. If device ID's are stored for heart rate and cadence there will be spinning dials for
these metrics as well.
POWER CONSERVATION
The computer and hub have power saving features to prolong battery life. The computer powers
down the display after four (4) minutes of inactivity. Press either [MODE] or [SELECT] to activate
the display. Similarly, the hub powers down after five (5) minutes of inactivity. The transmission
icon will not be visible when the hub is asleep. To wake the hub spin the wheel and verify the
transmission icon is illuminated.
