FIGURE 1.
Checking Cell Coverage
•
Once the startup procedure is complete, the Signal Strength Indicator display will show the cell
signal strength the transmitter registers at its current location.
•
The cell signal strength can range from 0 to 9.
•
The higher the signal strength number, the better the signal.
•
A signal strength less than 3 will not provide reliable message transmission. A remote antenna
may be required.

* A blown fuse usually indicates a problem that needs to be corrected. Do not relace the fuse without
identifying and correcting the problem.
