User's Manual

First make sure that the communications device (ie:- radio, external modem) is on and set

to the correct data channel. Also verify the cabling and antenna connections. If you are

using mobile radios on a conventional radio system, then the channel LED on the MDC

should be illuminated.

Press the function key next to the SIGNON text. Enter any information prompted for

using the numeric keypad or keyboard and press ENTER. There may be several fields that

need to be entered.

After the last field has been entered and ENTER is pressed, the MDC will display the

message “SENDING…”

After a few seconds the message “Job Transmission Complete” will appear on the MDC

screen. If this happens, then the test was successful and installation is complete.

If the message “Could Not Deliver Message. Try Again?” appears then the test failed.

Check the connections and equipment again to try to isolate the problem. It might be

necessary to re-check the MDC Modem Level again.
