LED Indicator Guide RSSI Mode
This communicator has a Received Signal Strength Indication (RSSI) Mode that works similarly to the bars on a
cellular telephone. LEDs 2 through 5 will illuminate to represent the quality of the connection: the more LEDs
illuminated (i.e., the higher the number of bars), the better.
To enter RSSI mode, press either of the two RSSI buttons. These buttons behave identically. The button on
the circuit board is easier to access if the cover is open, while the side RSSI button can be accessed when the
cover is closed. To use the side button, use the provided tool or an unbent paper clip. A simple press and
release of either RSSI button will place the TG-7FP in RSSI mode and another simple press will exit RSSI mode.
Note that while the RSSI button is held in, LEDs 2-5 will blink in unison once per second.
