Code 3 21TR & 21TR Plus - Manual (Page 11)

Notes:
*When the ArrowStik® Left and ArrowStik Right wires are both connected to +power, the Center-Out ArrowStik function is activated.
**When the Pattern Select wire is connected to +power and all other inputs are off, test mode is enabled to exercise all outputs in
sequence until +power is removed from the wire.
The priority for the 3-Level inputs is L3, L2 then L1 in that order. In other words, if power is applied to both the L1 and L2 inputs, the
L2 function will be enabled.
If the light bar is equipped with Steady Burning light heads, these heads are enabled with the 3-Level input wires. The jumper
plug must be moved to JP1, JP2 or JP3 to select the 3-Level input which will enable the Steady Burning heads, (see Figure 6).
The Steady Burn function for both the Take Down and Alley lights will always override the Wig/Wag Flash function.
The Cruise Light function is mutually exclusive with all other functions. If any other input has +power applied, the Cruise
Lights will be turned off. Light bars with software T116XXV6 or greater, T117XXV6 or greater or T118XXV2 or greater can
operate the Cruise Light Function and the Dim Function together. The Dim Function has no affect on the Cruise Lights.
Step 3
Continue applying +power to the GRN/BLK wire. Scroll to the next flash pattern by momentarily holding the Pattern Select wire (BLK/
RED) to +power for ~1 second, until the light heads switch flash patterns, and then releasing it. This will step to the next pattern in
numbered order as listed in Table 4 for the selected 3-Level mode. The new pattern is automatically stored each time. Repeat this
procedure for Level-2 and Level-3.
