to the transmitter ensures that fluids do not come in contact with the connector pins inside the
transmitter. Fluids can cause connector pins to corrode and affect the performance of the transmitter.
Do not twist the tester while it is attached to the transmitter. This will damage the transmitter.
The tester can be used for one year. If you continue to use the tester for more than one year, the
connector pins inside the transmitter could be damaged, because the tester cannot continue to
provide a waterproof seal. For instructions on how to check the connector pins, see Inspecting the
transmitter connector pins, page 21.
CAUTION: Only use the green colored tester (MMT-7736L) with the transmitter. Pockets on
the transmitter are visible when connected to the tester. Do not use any other test plug. Other
test plugs are not intended for use with the transmitter and will damage the transmitter and
the tester.
