OPERATION
FLX-20 Night Mode
Night Mode reduces the brightness of the display. This can make
viewing more comfortable in low light conditions. To activate Night
Mode, push in and hold the Gain Control until the brightness changes.
When you power o the FLX-20, it will revert to normal full brightness.
Low Battery Indicator
The FLX-20 will give you a low battery warning (10.6 volts) by
ashing the green depth lines around the inner side of the display four
times every four minutes. At 8 volts, the green depth lines will ash
continuously just before the system shuts down completely (6.5 volts).
All batteries are dierent, and how long you are able to sh after the
rst warning will vary. Note that this feature is designed for SLA type
batteries.
Vexilar Lithium battery voltage drops quickly at the end of the discharge cycle.
Therefore, expect the battery to die very soon after the rst low battery indications
appear.
