The Comtek PR-75a AutoSmart-Tuning Assistive Listening Receiver is an easy to use digitally synthesized monitor receiver. The receiver's AutoSmart-Tuning makes it easy to switch between multiple audio sources within the same building. The receiver's auto-on feature turns the unit on and begins searching for a channel as soon as you plug in earphones.
AutoSmart-Tuning
- This unique receiver will automatically turn itself on and initiate its AutoSmart-Tuning when the earphone is plugged in. The PR-75a's AutoSmart-Tuning process selects the closest appropriate transmitter in its vicinity and then sets itself to this channel. This also establishes the receiver's compatible frequency group when multiple channel operation is in use in the same area. A convenient one-button tuning control will cause the receiver to seek only channels belonging to its frequency group, eliminating the possibility of tuning to an incorrect channel
Single LED Indicator System
- During the initial tuning process, the LED indicator will blink very rapidly indicating channel selection. The LED indicator will illuminate continuously when a signal is being received. A steady slow LED flash rate indicates that the receiver is no longer receiving a signal. The LED will flash rapidly indicating that the 3 volt battery supply has fallen below 2 volts and the unit must be recharged or two new AA size 1.5 volt batteries are needed
- The PR-75 is compatible with the M-175 Personal Communication Transmitter, the BST-75 mini base station transmitter, and the BST-50b digitally synthesized base station transmitter
