■The sound is not heard from the earphones, or is only heard
from one ear.
• Make sure that the earphone connector is firmly connected to the device
(page 17).
• Make sure that the volume is not set to minimum (pages 42 and 59).
■The LED doesn’t flash even if I attach the pulse sensor.
• The LED flashes only during an exercise session in the Free Workout, Walk
Fitness, Jog Fitness or Training modes, or when the Checking HR display is
shown (page 72). In all other situations, the LED is off.
■My heart rate cannot be detected.
• Make sure to firmly connect the earphone cable to the device.
• Gently rub or massage your ear to stimulate blood circulation.
•Try changing the pulse sensor location.
• Adjust the sensitivity or the pulse sensor (page 66).
•Wipe the lens of the pulse sensor with a soft and dry cloth. If dirt, oil or sweat
adheres to the lens of the pulse sensor, your pulse may not be detected
properly.
■Song doesn’t change even when I speed up or slow down the
pace.
• Adjust the Pace Sensor and/or Step Sensor settings (page 66).
■The device becomes hot during charging.
• Some heat during charging is normal. However, if the device becomes
extremely hot, some malfunction may have occurred. Have the device
inspected by qualified Yamaha service personnel.
■Power cannot be turned off while charging the battery with the
AC power adaptor.
• This is normal. The BF-1 is always on during battery charging, for power
control purposes, when connected with the optional AC power adaptor.
■It takes a certain amount of time to start up and/or shut down.
•This is normal and indicates that the device is analyzing the music data and/
or exercise log data. (Depending on the data size, this may take a few
minutes.)
■One song (or a few songs) is repeatedly played while
exercising.
• There are few songs which match in tempo to your exercise pace in the BF-
1. Make sure to load more songs of the appropriate tempo from your
computer or set the Music Priority setting to “Mix” or “BODiBEAT Songs”
(page 61).
