Product description
To deliver reliably coded heart rate information, your smartLAB®runner
pulse watch utilizes a safe 122 kHz low frequency. So, all you have to con-
centrate on is getting the most from your exercise.
Each time you put on your chest transmitter and then press the MODE key
until the heart symbol appears, a code is randomly selected and transmit-
ted to the smartLAB®runner watch receiver. Thereafter the watch will lock
on to this code plus the transmission interval to create an interlock.
The code combined with the precise transmission interval results in the
unique interlocking pairing between the chest transmitter and the watch.
The interlock code can be displayed by pressing and holding down the
SCAN/REV key until the word CODE and a number appears on the screen.
During the interlock process you should be at least 6 feet (1,8 meters) away
from other heart rate monitors. If the interlock is lost for any reason, the
watch will beep once to alert you and the heart rate will go to zero. In this
case you should repeat the interlock process.
