Caution:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.- Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.- Consult the dealer or an experienced radio/TV technician for help.

Troubleshooting
If the computer is not picking up your hand pulse signal (or you are getting
inaccurate readings), please adjust the following:
1. Slightly moisten/dampen the palms with water so the sensors can detect a
pulse signal.
2. Do not grip the sensors too tightly. Only moderate pressure need be applied.
Gripping the sensors too tightly restricts and seizes detection of your pulse.
3. Remove any rings or jewelry to prevent interference.
4. Check to ensure all pulse sensor wires are properly connected and are
not damaged.
You may need to refer to installation/assembly directions for the pulse sensor
wires in this manual.
If the computer is not displaying the CALORIES/DISTANCE/TIME/(ETC.) functions
(or you are getting inaccurate readings), please adjust the following:
1. Check to ensure all computer sensor wires are properly connected and are
not damaged.
You may need to refer to installation/assembly directions for the sensor wires
in this manual.
If the computer display is blank & not displaying any data (or does not appear to
power on), please adjust the following:
1. Check to ensure all sensor wires are all properly connected and are
not damaged.
2. Check to ensure the AC Adapter* or Batteries* are properly plugged in or
fully charged.
