Display with 7 inch or 24 inch high digits can display
speeds from 0 to 199. It includes an integrated
battery charger and wireless receiver.
Battery pack with integrated battery charger and

Wall transformer to charge the battery inside the
battery pack with built in transmitter.
Operation
When the display is not used for extended periods of time, the
internal batteries will slowly discharge over time.
Set the display in the field where it is convenient for
easy viewing. It is best to have the radar gun in a
line of sight between the display and the radar gun.
Push and hold the ON button on the rear of the unit
for at least 2 seconds. The display should show a
test pattern when turning on.
Inspect the connector on the radar gun to insure that
no pins are bent or broken.
Attach the Jugs SI radar gun to the DB9 (9 pin
connector) on the battery pack. Be very careful to
not bend the pins when making the connection.
Tighten the 2 thumb screws. This will keep the
connector securely attached to the battery pack.
The radar gun display should come on and show “C”
in the display.
Test the connection. 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 by the tuning fork on both the radar gun
display and on the large remote display.
You are now ready for the game or other activity.
When finished for the day, re-connect both the display
and battery pack to the wall transformer and connect the
wall transformer to AC power when not in use.
Storage
When the display is not used for extended periods of time, the
internal batteries will slowly discharge over time.
It is very important to not permit the Gell Cell
batteries used inside these displays to completely
discharge. The battery life will be shortened
significantly is they are allowed to completely
discharge.
When the displays are NOT being used, it is best to
keep both the display and the battery pack plugged
into the charger. The batteries cannot be over
charged. The battery charger is an intelligent battery
charger that maintains a trickle charge to keep the
batteries at full charge, but shuts off when necessary
to prevent any possibility of over charging.
Your display will always be ready for use and should be
