IFB Receiver General Technical Description The IFBR5 was upgraded to the IFBR5a by adding a number of important and useful features: (1) Two rotary HEX switches to manually set the operating frequency, (2) Automatic sensing/control of a mono phone plug to eliminate the mono/binaural switch, and (3) A multicolor LED for battery status. The Frequency scan and memory features were retained.
R5a Frequency Adjust (fig. 2) To gain access to these switches, slide the access door sideways with a fingernail.

When a Mono plug is inserted, a special circuit senses the “ring” to “sleeve” short and automatically switches off the ring to prevent excess battery drain. To reset, switch power OFF then back ON.
