3. Getting Started
3.1 Introduction
The SVR™ is a hand-held surface velocity radar (SVR™) gun specifically
designed to measure the surface velocity of water—great for use in
streams and rivers . Features such as Recall allows you to review the
previous measurement . Other features are selectable through the
menu option .
The radar gun features a tilt sensor system, which internally
compensates for the cosine angle effect of the vertical (pitch-down)
angle of the gun to the target . It is not necessary to manually set the
tilt sensor .
3.2 Battery Charging
The SVR™ is designed to operate off of six (6) rechargeable Nickel-
Metal-Hydride batteries (or off the DC power cord) . When you first
receive your radar, the batteries will need to be charged for the first
time before using . Once batteries have been charged if you do not
use the SVR™ for 3-4 weeks, you will want to recharge the batteries
before use in order to get the full run time . To charge batteries for the
first time or to replace the batteries following steps 3 .6 to 3 .7 .
3.3 Removing the Battery Holder
The battery holder is located inside the handle of the SVR™ and is
accessed by means of a sliding door . When first received, the holder
should already have batteries installed, but if not then you will need
to remove the holder and loaded it with batteries . To remove the
battery holder slide the battery cover to the right until the battery
holder is released as shown in Figure 3 .3 . The door can be completely
removed from the slide .
