2.6 LRC Maintenance Mode
Maintenance mode is the gateway to the LRC transmitter’s various adjustable operating
functions –including association (Section 2.7), tilt switch activation/deactivation (Section Error!
Reference source not found.), and switch test mode (Section 2.9.1).
To Enter Maintenance Mode:
1. Turn the transmitter on. (See Section 2.3, steps 1–2).
2. When the SS LED lights steadily:
Quickly move both the SELECT and NEXT switches on the left-hand side of the
transmitter DOWN for approximately one second. The display reads “MM WAIT”.
 Note: If you wait too long to perform this operation, restart the process from Step 1.
3. The LEDs scroll from right to left:
And the display reads “MM.”
The unit is now in Maintenance Mode. Release the switches to perform further
operations.
To Exit Maintenance Mode:
1. Press the STOP switch DOWN.
This also shuts the transmitter down. Pull it up again to begin operations. (Section 2.3).
2.7 Associate LRC with the System Receiver

receiver identity (ID) in its core memory following successful association with the chosen

User Manual
U122.0.0
10
receiver. Systems are pre-associated at Cervis, Inc. before leaving the factory; but there may be
times when it is necessary to associate transmitters and receivers while in the field.
Use the process outlined in the following steps to associate a receiver with the LRC transmitter
when needed.
To Associate with Receiver:
1. Turn the transmitter on. (See steps 1–2 in Section 2.3).
2. Enter Maintenance Mode. (See steps 1–3 in Section 2.6).
3. While in Maintenance Mode, simultaneously lift and hold the SELECT and NEXT
switches on the transmitter’s left side UP for five seconds.
Release both switches when LED RA starts blinking:
And the Display reads “ASOC.”
You are now in Association Mode.
4. While in Association Mode, the SS and RF LEDs light steadily:
This indicates that the transmitter is attempting to locate any available receivers to Link
to. The transmitter builds a list of all possible receiver identities (IDs) that are in range
(usually only one).
5. When the RA and RF LEDs light steadily:
The transmitter has completed its search for available receivers. You can now pick which
receiver to link to.
6. The Association Relay on a found receiver starts pulsing. (During the process, an
LED on the bottom of the MU’s enclosure blinks when the receiver is selected.)

Locomotive Remote Control (LRC) System Manual

11
To select the indicated receiver, momentarily lift the SELECT switch UP.
To bypass that receiver and move to the next one in the transmitter’s memory,
momentarily lift the NEXT switch UP.
7. When you have found the receiver you want to control, press the green
START/RESET pushbutton again to pull in the “Radio Active” (MLC) relays.

User Manual
U122.0.0
12
 Note: Once you have selected a receiver and energized the MLC relays, the
Locomotive CB transmitter and receiver are linked (associated). The display reads
“L# XXXX”—where “XXXX” is the locomotive ID number.
 Notes:
•If you purchase a spare transmitter after the original system ships, you will need to
associate it yourself before it will work with that system.
•Each transmitter must be associated one time. Once associated with a receiver, that
transmitter will work with that receiver until the receiver ID is cleared (see Section 2.8).
The transmitter will work in a first-come/first-serve fashion, where only one transmitter
can ever be linked to a receiver unit at a time.
2.8 Clearing LRC Stored Receiver ID (Factory Reset)
The LRC transmitter stores its associated receiver ID in its internal memory. During instances of
severe interference—or perhaps when troubleshooting—it may become necessary to break the
established communications link between the transmitter and the system receiver. This is called
“clearing the stored ID”or “Factory Reset.”
To Clear the Stored Receiver ID (Factory Reset):
1. Turn the transmitter on. (See steps 1–2 in Section 2.3).
2. Enter Maintenance Mode. (See steps 1–3 in Section 2.6).
3. To reset the transmitter, simultaneously hold the SELECT and NEXT switches
on the transmitter’s left side UP and push the green START/RESET pushbutton.
Keep holding the switches and pushbutton in position while the transmitter resets the
receiver ID. LEDs RA and SS illuminate steadily when the reset is complete:
4. Release the SELECT and NEXT switches and green START/RESET pushbutton
to return to Maintenance Mode.

Locomotive Remote Control (LRC) System Manual
©2019 Cervis, Inc.
13
 Notes:
•When a transmitter is not associated with a receiver, the transmitter will illuminate all
the LEDs and then power down shortly after it is turned on.
•The receiver does not need to be on when clearing a receiver ID from the transmitter.
2.9 Maintenance Mode Special Features
2.9.1 Switch Test Mode
Switch Test Mode allows you to diagnose the Warrior LRC transmitter when troubleshooting a
potential problem.
While in switch test mode, you can test the transmitter switches, levers, and joysticks without
energizing the relays in the receiver (and consequently, unnecessarily manipulating the attached
machinery). As you manipulate the controls, the LEDs will light to let you know that the
transmitter’s printed circuit board (PCB) recognizes that switch movement.
✓ Note: You can test all switches except for the SELECT switch UP. (This switch allows
you to enter Switch Test Mode).
In switch test mode, the Battery, RA, and SS LEDs are used.
