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.
When power is applied to the unit, the display shows the startup screen for about 45
seconds.
Initial Checks
If the LLM-1770 is not functioning properly, first verify the following:

The LLM-1770 is connected to a power source (11-17 VDC).

All cables are correctly connected (see Connecting the LLM-1770 on page 16).
Initial difficulties with operation or display can be due to improper setup. Review the Setup
menus (see
Setup Menu Functions on page 35) to ensure that the proper adjustments
have been made for the signal requirements.
Restarting
If a problem persists after the cables are correctly connected and the unit is set up, restart
the unit by doing the following:
1 Push and hold the SETUP and CLR buttons for a minimum of five seconds until the SYSTEM
RESET message appears on the display.
2 Press and hold the ENT button to reset the unit’s configuration. All front panel and Setup
menu selections will be reset to the factory default settings.
