TEST MODE BY
COVERING BOTH PINS
-Re-install the AA Alkaline batteries in the RAIN TRANSMITTER once the jumper has been moved.
-Check LED on receiver to make sure it is blinking ORANGE every 4 seconds.
-Check the instruments to see if the error has been corrected.
-Unlike the WIND and TEMPERATURE TRANSMITTERS, the RAIN TRANSMITTER will not automatically
exit test MODE after 15 minutes. Therefore, you must take the rain transmitter out of test mode manually. To
do so: remove the batteries, then move the jumper on the RAIN TRANSMITTER circuit board back to covering
only one pin of the 2-pin terminal (it does not matter which pin is covered). Re-install the batteries and cover.
-If the instrument continues to display the error code, call Maximum for further assistance.
