To remove the SIM card, push the SIM card further into the slot, listen for the ‘click’sound and allow the SIM to spring free.

2NR3 Initial Setup
2.1 Install Battery
The NR3 allows two batteries to be installed. When installing the batteries, ensure the correct orientation with the positive end
towards the front of the device (see figure 10).
Access the battery bay by compressing the battery latch towards the inside of the device and pull up. This will swing the battery
latch open.
Figure 9: Battery Door Latch Location
Place the batteries into the designated spot and close the battery cover until the battery latch clicks into place. The projected run
time of the battery is ~6 hours.
Figure 10: Battery Installation
To remove the battery, compress the battery latch towards the inside of the device and pull up. The battery can now be removed
from the battery compartment.

2.2 Install on a Range Pole
Using the standard 5/8-11” mount on the bottom of the receiver, the unit can be secured to a field standard 5/8-11” range pole.
The receiver should be placed carefully on the range pole, to ensure cross-threading does not occur. Hand tighten (35-40 in-lbs of
torque) to secure the unit.
