2e MT-3000 Trouble-Shooting - Wiring Considerations
Verify the wiring of MT-3000 to the BI-3000 and BI-3000 to the WH-3000. If no wiring problem
exists, try moving the connection on the WH-3000 to another "J" connector (J3 -J10)
i If the keypad is displaying the tuner's frequency but is not controlling the tuner's preset
skip function, check to see that the tuner is loaded with at least two presets. Go to the
tuner, press the appropriate TUNER button repeatedly. If the tuner advances through
presets from its front panel but not from the keypad, there is a problem on the tuner's
ability to receive information from the keypad. This problem exists on the tuner's RX
line. Again test the wires for continuity on this line. If no problem is found with the wire,
you may need to open the tuner and check its DIP switch settings as described in the
Appendix for the MT-3000. Please note, the problem of the keypad displaying a tuner's
information but not controlling the tuner is typically due to the tuner not being loaded
with any presets and is not necessarily a problem for all three modules. Consult the MT-
3000's Installation Manual for programming presets. If the problem of the keypad
displaying information without the ability to control a tuner is due to an improper DIP
switch setting or damaged RX wire, the problem would be the same for all of the tuner's
modules.
ii If the keypad is not displaying the tuner's frequency but is controlling the tuner's preset
skip function, there is a problem on the tuner's ability to transmit information to the
keypad. This problem exists on the tuner's TX line. Again test the wires for continuity
