LED Operation for the Remote Unit: When the remote is seeking a connection, the LED will blink. When the connection is made, the LED will light continuously. The remote will also detect when a user direct-connects to the top of the unit. the remote will turn off the radio section and go into standby mode waiting for the connection to be completed. Once the connection is completed (the RS-232 line must be quiet for about 60 seconds), the remote unit will update and normal operation will continue. While in this mode, the LED will blink at a slower two-second interval.

LED Operation for the Base Unit: The LED will light contin- uously when the radio inside the module is on. Users should not leave the unit plugged into the cigarette lighter after finishing the survey. Standby current in this mode is approximately 40 mA, and will eventually run down a car battery.
