VTM-200 Installation and Operation Handbook 4-1
Section 4 ♦ Troubleshooting
CAUTION — these instructions are for use by qualified personnel only. To reduce
the risk of electric shock, do not perform this installation or any servicing unless you
are qualified to do so. Refer all servicing to qualified service personnel.
If the VTM-200 is not functioning properly, first verify that:
1. The VTM-200 is connected to a power source (90–264 VAC, 50/60 Hz nominal).
2. All cables are correctly connected (see Section 2, “Installation”).
Initial difficulties with operation or display can be due to improper setup. Review the
SETUP MENU (see Section 3, “Operation”) to ensure that the proper adjustments have
been made for your signal requirements.
For information on troubleshooting the RCU-200, see Appendix D, “Remote Control
Unit (RCU-200).”
Cold Starting the VTM-200
If the cables are correctly connected and the setup seems to be correct but the problem
persists, perform a cold start.
NOTE: A cold start resets all front panel and SETUP MENU selections to their factory-default settings.
All user settings are lost. See Section 3, “Operation,” for the factory-default settings.
To perform a cold start:
1. Disconnect the AC power cord.
2. Wait 30 seconds.
3. Press and hold the SETUP BUTTON.
4. Re-apply power while holding SETUP.
5. Release the SETUP button after the graticules appear on the SVGA monitor.
A cold start will cause the default SETUP Menu items to be read from the flash ROM
inside the unit. The default values will replace the custom setting selected. To see the
default values in the setup menu refer to Table 3-3 on page 3-14.
