There is a good solution to try when your transponder does not count laps,
we recommend to Read The Instruction Sheet supplied with transponder!
If that doesn't help fix the problem, check the power lead connection is OK,
check the plug and check the wires are not broken. If you replaced the lead
check the solder connection is OK and the positive/negative polarity is OK.
If the lead and plug checks ok, make sure the battery/power supply is OK.
If the power input is ok, check if the LED light comes on when the power is
connected, if the LED is on and the transponder does not count laps there
is a problem, you need to send to our address below together with a note.
If the LED does not come on/light up or flash and does not count laps you
need to send it to our address below for test/repair together with a note.
If your transponder counts intermittent laps the recommended solution
is to Read The Instruction Sheet supplied with transponder! Make sure
you read the part about installation and transponder location / mounting.
