Forcing a signal search
If the base station looses connection with the remote transmitter, the base station display will begin to flash %5 and all of the level
bars will be on. You should repeat the battery installation procedure to re-synchronize the units.
Horizontal vs. Vertical tank configuration
There are many configurations of LP tanks on the market today. The RS-228 is compatible with most. The RS-228 remote
transmitter is equipped with a configuration switch located in the battery compartment, which must be set to indicate what type of
LP tank is being measured.
If the LP tank is a horizontal cylinder, then the switch should be set to the HORIZONTAL setting (factory default).
If the LP tank is a vertical cylinder, then the switch should be set to the VERTICAL setting.
Care
Keep the system dry; if it gets wet, wipe it dry immediately. Use and store the system only in normal temperature environments.
Handle the system carefully; take care not to drop it. Keep the system away from dust and dirt, and wipe it with a damp cloth
occasionally to keep it looking new.
Modifying or tampering with the system’s internal components can cause a malfunction, can effect intrinsic safety and invalidate
its warranty. If the system is not performing as it should, please contact the place of purchase for assistance.
