User Manual Part 1

NOTE TO USER iiMTX5000 User and Technical Manual
• Software corruption can occur if the external input power
to the radio was momentarily lost and was then reapplied
without waiting a minimum of 10 seconds between loss of
power and reapplication of input power.
• The problem may also occur if the power switch was
pressed to off and back to on without waiting a minimum
of 10 seconds.
• To avoid problems, always wait a minimum of 10
seconds between removal or loss of power and
reapplication of power to the radio.
• The problem may also occur if the progress bar was
displayed when power was removed from the radio.
Always ensure the progress bar is not displayed on
the color LCD display panel when power is removed
from the radio.
If this problem has occurred, press the power switch to off, wait
10 seconds minimum, and press the power switch to on. The
internal processor will attempt to perform a self-recovery of the
software.
• During the software recovery attempt, a progress bar will
be displayed on the color LCD display panel indicating the
progress of the process. This progress bar will take more
time to reach 100% than during a normal power up.
• Do not become impatient during the software
recovery process due to the time it may take for
recovery. Do not remove and reapply power while the
progress bar is displayed during the software self-
recovery process. Software corruption will occur!
• When the power up is complete and the Main screen is
displayed on the color LCD display panel, verify proper
transmitter operation by transmitting and receiving.
• If the software is corrupted and the Main screen is not
displayed, contact MRC Technical Support for assistance.
Radio State Incorrect
If the radio state is incorrect, the correct Preset may not have
been selected. Select the proper Preset per “Select Preset” on
page 3-24.
PA Voltage Adjust Setup Software Hang-up
When performing “Perform PA Voltage Adjust Setup” on page 3-
44, ensure the Outdoor Unit (ODU) is properly connected to the
IDU. If the ODU is not connected to the IDU and you attempt to
perform this procedure, the software will hang up.
• To avoid software hang-up, always ensure the ODU is
connected to the IDU when performing the PA Voltage
Adjust Setup procedure.
• Check the Main screen ODU status indicator. If a major
fault exists in the ODU, do not perform the PA Voltage
Adjust Setup procedure until the fault has been corrected
or until the ODU is connected to the IDU.
• If the ODU is not connected to the IDU or if the ODU has
suffered a failure, the PA Voltage Adjust Setup Screen will
remain displayed on the color LCD display panel if the PA
Voltage Adjust Setup screen Start option button is
selected.
If the software hangs up due to the ODU not being connected to
the IDU or if the ODU has failed, perform the following:
• Press the power switch to off.
• Connect the ODU to the IDU or go to “Troubleshooting”
on page 4-1 to correct the fault.
