AMPLIFYING A WEAK SIGNAL CARRIER
If the signal strength is weak as indicated by Error Code 7 in Section 7.1, or if data transmissions are intermittent, an external
antenna can be used as a replacement to the small antenna supplied with the Guardian 1000™. The external antenna
connects directly to a Guardian with no adapter connector necessary, thereby improving the antenna’s performance. Please
contact FLO-CORP at 1-877-356-5463 for the available and supported external antenna options. The following outlines the
most common external antenna installation steps.
1) Position the external antenna at a location within cable reach of the Guardian’s installation and attach it to the Guardian
replacing the small antenna.
2) Holding the external antenna at the same location where the Guardian is installed (typically the top of the tank).
3) Test unit by initiating a data transmission with the external antenna, and observing the Error Code output in Section 7.1.
4) If the above test doesn’t produce any Error Codes as defined in Section 7.1, proceed to the next step. If the Error Code 4,
Error Code 7 or Error Code 8 still appears, see if the external antenna can be moved to a different location, possibly outside
the building or higher into the buildings roof.
5) Secure the external antenna using either the magnetic base, or the clamp base supplied with the antenna.
ESTABLISHING COMMUNICATION
Once all tank preparation has been completed, the Guardian 1000™ is properly mounted to the tank, the GSM SMS (Short
Message Service) is available, signal strength has been verified, and the number of callouts per day has been properly set, it
is now time to establish communications with the FLO-CORP Data Center.
1) Open the top cover of the Guardian opened by loosening the screw at the front of the lid using a 3/16” flat screwdriver.
Insert the two batteries into the battery holders at the inside-front of the housing and connect the optional extended life
battery pack if present (J7). Refer to Figure 12
2) Verify that the Guardian’s antenna is pointing straight up.
3) Press the white button on the right side of the unit. A green LED will light up at the inside front of the housing.
4) The green LED will flash fast (half second ON, half second OFF).
5) Once a cellular network is found, the green LED will flash slow (one second ON, one second OFF).
6) The green LED will go to solid ON for about 60 seconds while the unit is transmitting data to MonitorMyGuardian.com.
7) After a successful transmission, the green LED will flash and then go out. The Guardian is now in sleep mode, and will
remain in sleep mode until the next scheduled transmission time or until the white button is pressed again.
8) If the data transmission was not successful, a red LED will light and the green LED will flash an error code. Refer to
Section 8-1 of this manual for information on the error codes.
9) Contact FLO-CORP Customer Service at 1-877-356-5463 to verify a successful data transmission, and to verify tank
information.
10) Secure the top cover. Do not over tighten the screw.
UNIT ACTIVATION
VERIFYING GSM SIGNAL STRENGTH
During installation, you can determine your GSM signal suitability by operating a GSM cellular phone and confirming its
operation capability by placing a call.
