HIGHLIGHT: To highlight a parameter, use an arrow key to move the cursor until
that field displays in inverse video and a character position in that field is flashing.

TOGGLE: To toggle a field, highlight it and press the + or - key until it displays the
setting you want. For example, below Screen 4, on the Port A/B Parameter
Selection screen, you can toggle through various baud rates. Use the right arrow
key to highlight the BAUD RATE indicator and press the + key or - key to scan
through 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 to
the desired baud rate.
BACKLIGHTING: After two minutes of keyboard inactivity, the backlighting
automatically turns off to extend the life of the battery. To restore the display, push
any key. The e key is recommended, since it does not change the display.

Back Panel

Figure 1.3 shows the connectors and power switch on the back panel. The
receiver operates with an input voltage between 10 and 32 Vdc from an external
power supply.
Two POWER-IN sockets let you use two external batteries. When only one
battery is connected and it comes close to discharge, a continuous tone indicates
that the voltage has dropped below 10 volts.
You can connect the second battery to the second connector and continue
recording data without interruption. Or you can connect two batteries at once for
long unattended observations; the receiver operates from the battery with the
higher charge. Table 1.3 describes the items on the back panel.
