The 18R2 and firing module display the firmware version of the device first, such as, “5.1.0.” All devices synced together must use the same firmware version. To learn more about firmware versions and how to upgrade your system, at no cost, please see Firmware Figure Out.

Battery Life

The 18R displays the battery life range on a 1P scale, indicating a depleted battery with a 1P0 and a full battery with a 1P9. COBRA recommends only Energizer AA batteries and has a life of about six hours. The AA batteries power the entire controller including the RF module, LEDs, and 7-segment displays. As the battery level decreases, the amount of transmitting power is not reduced. For example, a controller at P1 has the same transmitting power as a controller with P9.

Note: The 18R displays “Lo” if the controller battery level is P3 or lower. If you see “Lo” followed by a 1P value, a channel, and an address, this is informing you a module or other device has a battery level of P3 or lower.

Self-test

“tSt” displays as the firing module perform the following tests:

LED function – When the key of the 18R remote is turned on the red and green LEDs will flash briefly.

Shorted / stuck button – During the self-test, if any button is pressed a false-positive to the shorted / stuck button test will occur and error code Er3 will display. If Er3 displays, power the system off, then back on, and do not press any buttons during startup.
