Code the receiver. Pick any combination of ON/ OFF
codes and set them on switch keys 3 through 8. Ignore Keys 1 and
2. The ON position is when the top of the switch is down. The OFF
position is when the top of the switch is up and the bottom is down.
The code set on Keys 3 through 8 on the receiver must now be
matched by all transmitters used in the system.

DESCRIPTION
four-channel wireless radio controls designed for use with
automatic garage/gate operators and access control systems. The
receivers can be activated by any of the Delta-3 format
transmitters. Receivers must be mounted at least 8 feet apart.
The Delta-3 radio format provides 256 different digital codes. The
codes are set using the 8-position coding switches in the units.
CAUTION: All transmitters and receivers should be
recoded by the installer prior to operation.
In order to avoid the possibility of duplicating codes in adjacent
systems, factory set codes should not be used. In addition, among
the valid codes available, four others should not be used. These
include: all keys set ON or OFF and keys set alternating ON/OFF.
Activate each transmitter to test the equipment.
WARNING! BE SURE DOOR OR GATE
AREAS ARE CLEAR OF OBSTRUCTIONS
STEP 3
Code the transmitters. Remove the battery access door
located on the back of the transmitter case to set transmitter codes.
Transmitter keys 1 and 2 determine which channel the transmitter
will activate. Keys 3 through 8 must match keys 3 through 8 on
the receiver. Refer to transmitter code set instructions to code
multi-button transmitters.

Linear radio controls provide a reliable communications link and fill an important need in portable wireless
signaling. However, there are some limitations which must be observed.
For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15
devices. As such, they have limited transmitter power and therefore limited range.
A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals
that occur on or near their operating frequencies, regardless of code settings.
Changes or modifications to the device may void FCC compliance.
Infrequently used radio links should be tested regularly to protect against undetected interference or fault.
A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale distributor or
dealer, and these facts should be communicated to the ultimate users.
This device complies with FCC Rules Part 15 and IC Canada Rules and Regulations. Operation is subject to
the following two conditions: (1) This device may not cause harmful interference and (2) this device must accept
any interference received, including interference that may cause undesired operation.
