A screen will appear with the MEYER logo for
approximately 3 seconds, after which an operational
screen will appear. The operational screen will
show:
The E-78 or E-88 icon on the left of the display indicates
that the PCM is functional and communicating to the
RCM. The icon on the right of the display indicates
that the HCM is functional and communicating to the
RCM. If the RCM should lose communication with the
PCM or HCM for a certain length of time, this icon will
disappear from the display.
The ALM function is only available when ther PCM and
HCM are recognized and found in the system by the
RCM. When ALM is not available, the button labels
for them will not be displayed. The WW button label
represents the WigWag plow light function. If there
isn’t a plow in the system, WigWag is not available and
the WW button label will not be displayed.
If the RCM does not display the PCM or HCM icon,
check that the device’s power connector is securely
plugged in. When the device is powered on, the RCM
will automatically detect it and put the appropriate icon
and button labels on the display. The RCM searches
for devices when it is powered on. Power cycling the
RCM can be used to try to find the devices. There is
a “FIND DEVICES” item in the Menu that will allow the
RCM to search for devices.
The LED backlight turns on when the RCM is powered
on. It will shut off after 30 seconds. It can be turned
on again by pressing any button.
NOTE: If RCM is powered on during the Mounting/
Dismounting sequence, the plow lights will flash and
the plow will no longer mount/dismount.
