MAINTENANCE AND REPAIR
FUSES
Each channel of the RE-121 is protected by a 10 Amp, 250 Volt, fast acting fuse located on the front panel of the
unit. If the total load for a channel is greater than 1200 Watts the channel fuse will blow.
There are also two 1/2 Amp., 250 Volt, fast acting fuses on the front panel to protect the internal electronic circuits
from an overvoltage condition. These fuses may be replaced ONLY by fuses of the same size and type.
TROUBLESHOOTING
VERIFY THAT ALL POWER IS REMOVED BEFORE HANDLING THE UNIT.
• Verify that the unit channel addresses are correctly set.
• Check that the console is powered and that console channels are correctly patched or set.
• Check the control cable between the dimmer and its console.
• Verify the loads and their connections.
OWNER MAINTENANCE
There are no user serviceable parts inside the unit.
The best way to prolong the life of your unit is to keep it cool, clean, and dry. It is important that the cooling intake
and exit vent holes are clean and unobstructed.
