Question:
What is the difference between the mPTX and mPTX Pro transponder?

Answer:
The only difference between them is the type of lead used. The mPTX has a standard Black/Red lead, the mPTX Pro has a custom produced Black/Black lead.

Question:
My transponder is not counting, what should I do?

Answer:

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. Be sure to try moving the transponder to another location, please read MRT mPTX Transponder Basics Knowledge Base Article MPTXOB0317 for information about mPTX Fast flashing LED weak signal warning.
