ABSTRACT:
A multi-channel remote control transmitter is disclosed for control of apparatus such as vehicle security systems, garage door openers, and the like. The transmitter provides the capability of selecting one of many different channels or codes to be transmitted with a minimum number of control switches. The transmitter includes at least one channel select switch and a transmit switch. The user actuates the channel select switch to select a desired channel, and then actuates the transmit switch to actually transmit the selected channel code. The transmitter includes an audible or visual indicator for confirming to the user the particular channel selected. The transmitter provides an audible "battery low" signal when the battery voltage drops below a predetermined level.
