Description The Delta-3 DT-4B digital transmitter is a four-channel wireless
radio control designed for use with automatic garage/gate operators and access
control systems. The transmitter can be used with one 4-channel receiver (DR4),
two 2-channel receivers (DR2) or four single-channel receivers (DR,DRQ or DRM).
Receivers should 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.
The transmitter is powered by a 9-volt battery. It should last 12 to 18 months with
normal use. The red LED on the face of the transmitter will glow when the unit is
activated. When it lights dimly, or not at all when transmitting, the battery needs
to be replaced.
STEP 1: Locate coding switch. Remove the ba
ttery access door located on the
back of the transmitter case. Identify the coding switch and note that it has eight
positions, with ON and OFF clearly labeled.

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.
• 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.
