1-3-2. URX-M2 Checking
The following procedures describe how to prove URX-M2 whether it needs to be required or not.
Equipment Required : MB-X6 (quality unit) / MB-806A (quality unit)
URX-M2 (quality unit)
1. Install the URX-M2 (repair unit) to be checked in an MB-X6 / MB-806A (quality unit).
2. Check if there is any fault using the MB-X6 / MB-806A (quality unit).
. If there is a fault, URX-M2 is defective.
Check the URX-M2 then fix a faulty section, and perform “2. Electrical Alignment”.
. If there is no fault, the URX-M2 (repair unit) is not defective. The original MB-X6 / MB-806A on
which the URX-M2 (repair unit) had been mounted is defective.
1-3-3. Error Messages
When an error occurs, any of the following error messages can be generated by the self-diagnostics
function that is built-in the URX-M2 and can appear on the display section.
Message

Error contents
An error occurs in EEPROM data.
The PLL synthesizer circuit does not
lock.
Power supply voltage has exceeded
the range of allowable limits.
The tone signal does not exist, or
any tone signal radio wave other
than 32 kHz is received and the
audio signal is muted.
If you turn on the power while
pressing the “SET” button and the
“_” button at the same time, the
squelch function release mode is
set, and this message appears once
before the display of normal
operation appears.
Remedial measure
Take both of the following remedial measures.
. Write the frequency data that corresponds to the
desired destination location, into EEPROM.
. Perform the RF squelch adjustment and the RF
level indicator adjustment. (Refer to Section 2-3.)
If the frequency data that does not corresponds to
the desired reception frequency range is written:
Write the correct frequency data into the EEPROM.
If the error message is displayed even though the
frequency data is correct:
Check the PLL synthesizer circuit (IC301, X301,
Q305 and Q306 and its peripheral circuits on the
MB-1129 board).
Use the equipment with the power supply of the
specified voltage range.
An interference radio wave has occurred in the
frequency band in use.
. If an error is displayed while the power of the
transmitter is on:
Turn off the power of the transmitter.
. If the RF level indicator of the receiver LCD lights
even when the power of the transmitter is turned off:
Set the frequency of the transmit/receive channel
that is free from the interference radio wave.
When the error is not caused by the signal interference, the tone squelch circuit of receiver or transmitter
(both receiver and transmitter) is defective.
. Check the receiver : Check the tone squelch.
(Refer to Section 2-3.)
If the tone squelch does
not work well, check the
tone squelch circuit (IC406
and its peripheral circuit
on the MB-1129 board.)
. Check the transmitter : Refer to the Service
Manual of transmitter.
Turn off the power once and then back on without
pressing any button.

The tone signal does not exist, or
any tone signal radio wave other
than 32 kHz is received and the

If the “SET” button and the “_“
button are pressed at the same time,
the UTX-P2 enters the default

Remedial measure
With “Error1” displayed, press and hold the “-“ button for 20 seconds to
read the backup data.The data is successfully read when “RELOAD” is
displayed. If the data fails to be read, check the peripheral circuits of
IC671, and perform the following measures.
. Write the frequency data that corresponds to the desired destination
location, into EEPROM.
. Perform the RF squelch adjustment and the RF level indicator
adjustment. (Refer to Section 2-4.)
If the frequency data that does not corresponds to the desired reception
frequency range is written:
Write the correct frequency data into the EEPROM.
If the error message is displayed even though the frequency data is
correct:
Check the PLL synthesizer circuit (IC321, X301, Q341 and Q342 and its
peripheral circuits on the RF-130 board).
Use the equipment with the power supply of the specified voltage range.
An interference radio wave has occurred in the frequency band in use.
. If an error is displayed while the power of the transmitter is on:
Turn off the power of the transmitter.
. If the RF level indicator of the receiver LCD lights
of the transmitter is turned off:
Set the frequency of the transmit/receive channel that is free from
the interference radio wave.
When the error is not caused by the signal interference, the tone squelch
circuit of receiver or transmitter (both receiver and transmitter) is defective.
. Check the receiver :
. Check the transmitter : Refer to the Service Manual of transmitter.
Turn off the power once and then back on without pressing any button.
Do not press the “SET” button and the “_“ button.
Check the tone squelch. (Refer to Section 2-4.)
If the tone squelch does not work well, check

Boards requiring use of unleaded solder are printed with a

(Caution: Some printed circuit boards may not come

: LEAD FREE MARK
m
. Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recommended to use the soldering iron having a temperature
regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful.
