West Mountain Radio Operating Manual
Additional Modes
Automatic Battery Save Mode
The PWRguard PLUS is designed to protect a battery from any additional
current drain following a long turn off period of 60 minutes. This “Sleep Mode”
will further reduce battery power drain by limiting the on time of the Yellow
LED. Normal operation will be restored when the input voltage returns to the
safe operating range, and the unit is manually or automatically reset. When
the unit is in Sleep Mode there is very limited power drain.
Voltage Sensing Circuits
Units are factory calibrated for the specified trip points and delays.

USB Programming Instructions
Download and install the West Mountain Radio port diagnostics utility or use
another terminal program, such as Hyper-Term. During installation, be sure to
install the drivers on the PC. The utility can be set to start every time the PC
powers up and it is always on the tool tray (lower right) or to just run it when
needed.
Open the PWRguard Plus unit and power it up. When the LED is on, connect
a micro-USB cable (not included with unit) between the PWRguard Plus
and the PC. The first time, Windows will attempt to install the driver. If the
diagnostic utility was previously installed, Windows should find the driver on
its own. Now the Yellow LED should be rapidly blinking.
