connector on the display. Be very careful to not end
the pins when making the connection.
Tighten the 2 thum screws. This will keep the
connector securely attached to the display
Attach the other end of the ca le to the data port on
the radar gun.

come on and show “C” in its display. The R2020
should show “00” indicating it got data from the gun.
To test the gun, thump the tuning fork supplied with
the radar gun and place it in front of the radar gun.
The display should show the speed value
represented y the tuning fork on oth the radar gun
display and on the R2020 display.
You are now ready to use the radar gun system.
When finished for the day, re-connect the display to the
wall transformer and connect the wall transformer to AC

significantly if they are allowed to discharge too
much.
When the displays are NOT eing used, Push and
Hold the OFF utton to turn the display off, then
connect the display to the wall transformer and plug
the transformer into AC power. The attery charger
is an intelligent one that maintains a trickle charge to
keep the atteries at full charge, ut shuts off when
necessary to prevent any possi ility of over
charging.
Your display will always e ready for use and should
e a le to run all day on a single charge.
