In an unobstructed outdoor area a range of 3.3 miles or greater “line-of-sight” is possible but indoor
“obstructed” range will be much less. Reflections and obstructions, depending on the density and material,

This is one of the biggest problems called in. If you are not using our cables, check your cables first. If you have

Appendix C

RF Serial Pin-outs.

System, Device Manager, Ports (COM & LPT),
COM Port, Port Settings, Flow Control.

If the battery is very low, when turned on, the Terminal will just keep beeping; it is cycling power, over and
over because the batteries are too low.
•
If the batteries are at a specific low point, the laser triggering or playing a voice message will be just enough
extra power draw to force the terminal to cycle power.

Charge your Terminal for at least an hour and try again.
I get 6 beeps when the RF Terminal powers up...
