Add additional keypad codes. Repeat Step 3 for
each keypad code required. Be sure to press the receiver’s
program button

Review memory. Press and hold the receiver’s
program button (channel one or two) until the LED begins to flash

of flashes. The number of flashes equals the number of
transmitters and keypad codes programmed into that channel of
the receiver.

seconds, the receiver’s memory for that channel will be erased.

IMPORTANT !!!
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.
