Introduction:  
The SK-910R3Q and SK-910R4Q are wireless receivers that meet the growing demand for multi-channel receivers with  
multiple and independently controlled output modes. RF receivers can be used to control a variety of home automation  
devices such as garage door openers, lights, motorized gates, lifts, or other devices remotely.  
These receivers are compatible with both fixed code and code hopping transmitters. Code hopping transmitters, such as  
SECO-LARM CODEBUMPtransmitters, change codes every time transmitter sends a signal for extra security. See page 4  
of this manual for a list of compatible transmitters.  
Installation Notes:  
1. Mount the receiver out of sight in a location where it is not exposed to the weather or moisture, and where it is not  
surrounded by metal. Metal will block the RF signal, resulting in a reduced range.  
2. For best range, pull the antenna wire as long and straight as possible. If the receiver receives interference from local RF  
activity (e.g., an airport or military base), the antenna wire can be folded. DO NOT CUT THE ANTENNA WIRE.

Transmitter Programming Button Operation (One per Channel):  
Learn mode  
Press and hold the transmitter programming button for three seconds or more.  
Press and hold the transmitter programming button for three seconds or more, then when the  
LED starts flashing, press again for three seconds to delete all previously learned codes.  
If this channel was programmed for latch output, once the relay is turned ON with a transmitter  
button, press the transmitter programming button of that channel once to turn the relay OFF.  
Press and release the transmitter programming button to show the number of codes stored. The  
LED will flash a number of times corresponding to the number of codes stored.  
Clear memory  
Reset latched output  
Memory display  
LED Indication (One per Channel):  
Senses signal from a transmitter button in normal operation, or indicates a transmitter button’s  
code already exists in the receiver’s memory during code learning.  
Steady ON  
In the code-learning mode or channel memory display mode, or during the programming channel  
output mode.  
A transmitter button code was learned, or the relay is in timed output mode.  
All previously learned transmitter buttons were deleted, or the relay is in toggle

In the normal operation mode, pressing the channel mode button once will display the number of  
codes learned.

Extended Range Antenna (Optional):  
Extends RF receiver range up to 1,000ft (304m) (open air) with  
existing remotes.  
SK-91ERSD  
Comes with a 9ft cable that easily plugs into the 3-pin antenna port  
located on the RF receiver.  
NOTE:  
If an extended range antenna is used, the “LP3” on the receiver PC  
board must be cut.  
Actual antenna range will vary greatly depending on the operating  
environment.
