*** DO NOT SEND TRANSPONDER until you read this ***

If the light comes on and no signal is detected by the timing system we CANNOT repair this problem.

Only service available for TranX DP transponders is repair or replacement of broken power lead.
If lead is cut or broken completely off we can refit the lead or replace it.
Lead connection is made inside transponder so it is repaired correctly and is NOT a splice on job.
If you still have the cut off lead please send it with the transponder as it can be reused.

In some transponders the LED light fails to work but the transponder still works OK
To test for this apply power to the transponder and place an AM radio tuned off-station near the transponder.
If noise is heard more near the transponder then this confirms the transponder is producing a signal.
However we recommend you have a race venue confirm the transponder signal is fully readable before using in racing.
The LED light can be replaced but we recommend not doing so because it is expensive and not really required for the transponder operation.

All Mylaps DP transponders have a 3 year warranty, contact Mylaps for warranty service.

Futher info

This AMB Mylaps transponder is popular in full size motor sports and requires the connection of an external 12 volt DC power supply. Ideally it should be connected directly to the vehicle battery to ensure the most stable power source is used. The battery acts as an extremely good voltage regulator so avoid connecting the transponder to engine ignition devices as power spikes can be emitted by those components.
