Precautions and Warranty
Installation notes
Radio receiver dimmers
WACE RFD250W CEFL RFD250W CEVO RFD250W
EXRF D250W PORF D250W
DANLERS radio receiver dimmers can be user programmed to respond
to any DANLERS radio frequency (RF) manual (or slave) sender. With
a manual sender the radio receiver dimmer will switch the load on full
when a programmed DANLERS RF sender up button is pressed quickly
and dim it up with a sustained up press. A quick down press will switch
the load off and a sustained down press will dim the load down.
With a slave sender, the radio receiver dimmer will match the state of
the device plugged into the slave sender - fully on or off.
The dimming technology used is ‘Trailing Edge’, ideal for
most
low
voltage transformers and direct mains dimmable CFL & LED lamps.

Preprogrammed options
DANLERS radio receiver dimmers can be factory programmed, with the
assigned senders, to perform more complex functions, such as:
• Minimum and maximum dimming limit
• Variable manual dimming speed
• Automatic gradual dim On (max 4 minutes)
• Automatic gradual dim Off (max 4 minutes)
• Dim to a preset value over a preset time (max 4 minutes)
Troubleshooting
Radio receiver dimmer does not respond to sender:
• Ensure the sender is correctly assigned to the radio receiver.
• The sender is too far away or RF absorbed by building or trees.
Move sender closer to radio receiver or consider using a repeater.
• The sender battery is at (average life approx 5 years).
Change battery making reference to sender installation notes.
Load and receiver LED ash twice each time the sender is pressed:
• Ensure the radio receiver dimmer is not in programming mode.
Radio receiver stops working:
• The load or in-rush current is too large and has damaged receiver.
Ensure mains halogen lamps include a thermal safety fuse.
