SECTION 18 TROUBLESHOOTING
This section provides procedures to solve some common problems that may occur with the RI-300. Use the following checklist
if you are experiencing problems with your controller.
1. Confirm that you have 12 VDC power connected to the correct pins.
2. Turn on power to the repeater. The system LED should be the only LED on. If other LED’s are on, see the following
problem list.
3. Apply a carrier without a CTCSS tone on the input of the repeater. The COS LED should come on and system LED should
go out.
4. Apply a carrier with 100Hz CTCSS tone on the input of the repeater. The COS and the CTCSS LED should come on. The
System, DTMF, AUX, Hook LEDs should be flashing 4 times per second.
5. Apply a carrier with a DTMF tone on the input of the repeater. The DTMF LED should stay on steady.
6. With the controller connected to your computer and programming software running. Confirm that the co rrect CTCSS/DCS
is being decoded. Check all DTMF decode by sending all DTMF characters.

PROBLEM SOLUTION

No Green System LED +12 VDC power source not connected or voltage below 8VDC minimum.
S-Command 01 (system on/off) is off and or S-Command 11 (display on/off) is off.
If the COS LED is on, you may have a signal on the input of the repeater without the
correct tone squelch. If the unit has adequate voltage, and the S-Commands are correct,
there may be some type of hardware failure.
No COS yellow LED Confirm the receiver is on channel.
COS yellow LED on all the time Confirm the receiver audio input level and the squelch level adjustments are correctly set.
Check that the discriminator audio input is connected and working. If your discriminator
does not have adequate filtering for 455 kHz, you will have to provide for this filtering
between the radio and controller. You may also have a signal on the input of the
repeater.
No RPT-TS yellow LED CTCSS may not be responding because either the controller or the input signal does not
have the correct CTCSS tone or DCS code. Confirm that the COS LED is working and
the receiver audio level is correctly set. You can also use the programming software to
view the current tone/code being decoded.
No PTT red LED If COS and PL operate properly, then check that the S-Command 01 and 02 are set
correctly.
No DTMF yellow LED Confirm that the COS and CTCSS LED is working and the receiver audio level is
correctly set. CTCSS tone may not be correctly set for DTMF control. This LED should
light with the beginning of the first valid DTMF and go out with a function complete or
the inter-digit timer, timing out.
No Aux input yellow LED Valid only when the Aux input is connected to another RI-100 controller or a control
receiver. When connected to another RI-300 confirm all the Aux function are correctly
enabled on both controllers
Password will not respond The unit is not recognizing the password that is being sent, this can occur because of an
error in sending the Password or the system password was accidentally changed. In order
to get to a known password, the system EEPROM will need to be re-initialized.
UN-LOCK LED flashing The RI-310 controller will flash this LED when the VXR-5000 PLL is not locked.
Confirm your receive and transmit frequency. You may want to reprogram these
frequencies with the programming software.
VXR-5000 transmit power
changes You may not have correctly programmed the VXR-5000 high and low power macros.
See section 7 for details on setting up the transmitter power level.
Error message when functioning a
user command The function error is in response to an error in an S-Command within the macro. You
can use the programming software to locate this error.
You may need to add an alternate
command termination (default is
inter-digit timer) to terminate the
commands so the controller will
decode the command.
You may be experiencing a problem with the COS always on. Check that the receiver
and squelch levels are properly adjusted.
