The recorder continuously monitors the battery voltage.
A “LO BAT”
indication in the upper left-hand corner of the main LCD (refer to Figure 2-6)
indicates that only one to two weeks of reliable battery operation remain, and
that the batteries need replacing within this time frame. Also, if the unit is
operating under battery power and the battery voltage is too low to permit
reliable operation, the system shuts down and displays “---” in the LCD
. The
system may be restarted by changing the batteries or by the re-initiation of ac
power. If ac power fails, the circuitry will attempt to automatically switch to
battery backup. If viable battery power is available, the system will operate on
battery power until the batteries fail or ac power returns. When ac power
returns, the recorder will automatically reset itself (refer to Section 8.5).
Figure 2-6. Battery Warnings
2.3.2 Connecting ac Power
The recorder can be ac powered using the 9Vdc, 1Amp ac adaptor supplied. The
ac power jack is located on the right side of the unit (refer to Figure 1-1, item #6.).
Make sure the power switch on the control panel (refer to Figure 1-1, item #7) is
in the OFF or “O” position when plugging in the ac adaptor. The adaptor cable
is 6 feet (2 meters) long.
