“Good,” contact your dispatcher or fleet manager for assistance.
3. What does “Buffer Full” mean?
The transmit buffer in the unit has all the messages it can hold. Your unit can hold up to 3
messages while it is waiting to transmit. If the Msgs Being Sent field on the View Status
screen shows 3, you can’t send additional messages until at least one has been received
by the NMC. This may occur when the No Signal Light is on. If so, move the vehicle away
from any obstructions. If you get this message when the No Signal Light is off and the
Status field on the View Status screen is “Good,” contact your dispatcher or fleet manager
for assistance.
