Out Of Range/System Inoperative
EDACS - A single low pitched tone will sound immediately after the PTT switch is keyed indicating the radio is out of range of the repeater. The radio tries to place the call for a short period (3 seconds) after the initial attempt. The radio generates a second low pitched tone when it gives up trying to place the call. The system is off the air or the radio needs servicing when the radio is within calling range, and these tones are heard.
ERROR MESSAGES
E3 - If at anytime the Synthesizer is unable to load and lock on the channel properly an "E3" message will be displayed in the System field and the Group/Channel field will be blanked. If the "E3" message is displayed on all systems, the radio has failed or has not been programmed properly. The radio’s buttons and keys will still operate with an "E3" message displayed.
E9 - "E9" message indicates the Personality has not been programmed into the radio.
