Phonic Ear Model PE441T/PE442R FM System The Phonic Ear Model PE441T/PE442R FM system was made by Phonic Ear Ltd. of Mill Valley, CA around 1975. It consisted of a wireless microphone which the person speaking wore and the pager-like FM receiver which the hard of hearing person wore. Both units were the same size and measured 3⅛" x 2¼" x 1" (7.9 x 5.7 x 2.5 cm) and weighed 2½ oz. (70 g). |  | Click picture for larger view | | |   | | | |

| View of the Phonic Ear Model PE442R FM receiver showing the crystal frequency module removed. Each module had two color-coded dots indicating a given frequency. The transmitter and receiver had to have the same color codes in order to work with each other. Note the same yellow and blue colored dots on the transmitter in the next picture.

| Upper front view of the Phonic Ear Model PE441T FM transmitter showing the yellow and blue color-coded dots (upper right). This tells you that this transmitter will work with the receiver with the same color-coded dots (shown above). Note that the transmitters came with the crystals already installed and couldn't be changed. Thus you had to purchase a receiver and a module with the same frequency-coded dots the transmitter had in order for them to work together. |  | Click picture for larger view | | | |

| View of the external battery cord of the Phonic Ear Model PE442R FM receiver. This cord plugged into a 9-volt battery and the other end plugged into the battery jack on the right side of the receiver (shown in above picture). I'm not sure why you used this arrangement instead of just replacing the battery in the battery compartment when it died. Perhaps it was so when you used a rechargeable battery in the battery compartment and it needed recharging you didn't have to take it out and possibly lose it. You just plugged in the external battery until you had time to recharge it. |  | Click picture for larger view | | | |
