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 cellular connection: the more
LEDs illuminated (i.e., the higher the number of bars ), the better.
A simple press and release of the RSSI button will place the communicator 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.
