STATUS INDICATORS
As shown in Figure 8, the DL’s front endcap has three multicolor lights to indicate the status of Power, Position, and
Logging, respectively, from left to right. For a labeled view, see also Figure 1, Page 11.
Figure 8: Status Indicators
Table 4 shows what the colors of each indicator signify. When the DL is connected to two batteries, the Power indicator
is pulsed (in the appropriate color) to distinguish between battery A and battery B. One long “blink” corresponds to
battery A, and two short blinks in rapid succession correspond to battery B. Only the status of the active battery is
indicated.
Note that during initial power up of the DL or upon wake up from sleep mode, the lights on the DL indicate self-test
conditions and therefore the following table does not apply at that time.
Table 4: Status Indicators - Meaning
Indicator Color Status Description
Green Input voltage is good. The light blinks in a single-blink pattern (e.g. ) if Battery A is good, and in
a double-blink pattern (e.g.
) if Battery B is good.
Amber blink The light blinks in a single-blink pattern (e.g. ) if Battery A is low – battery voltage is less than
10.7 Volts.
Amber double
blink
The light blinks in a double-blink pattern (e.g. ) if Battery B is low – battery voltage is less
than 10.7 Volts.
Amber Switching batteries.
Power
Red There are no good batteries available. Operation is disabled.
Amber fast blink High temperature warning.
Red fast blink High temperature shutdown.
Amber slow blink High temperature shutdown. Temperature returning to normal (blinks once every five seconds).
Red slow blink High temperature shutdown. Waiting for temperature to return to normal (blinks once every five seconds).
Dark No power, or DL in sleep mode.
Position Green Valid position solution; fine time reference set.
Green blink Valid position solution; fine time reference not set.
Amber Position fixed; fine time reference set.
Amber blink Position fixed; fine time reference not set.
Red Insufficient satellites for position.
Dark No power, or DL in sleep mode.
Logging Green PC Card in, memory capacity OK.
Green blink PC Card in, logging to PC Card in progress and memory capacity OK.
Amber PC Card in; memory capacity below 10%.
Amber blink Logging to PC Card in progress, less than 10% capacity remaining at current logging rate.
Amber slow blink Sleeping: waiting for scheduled event (blink once every 5 seconds).
Red PC Card in; memory capacity full.
Red Blink PC Card in; error encountered while trying to access the PC Card.
Dark Power off or PC Card not detected, or initialized.
When the DL is connected to an AC/DC converter, the Power indicator may be ignored as long as the color is green; if it
turns red, then you should investigate whether there is a problem with either the AC supply or the converter itself.
