Adding Wireless Sensors
Verify Wireless Signal Strength
After temporarily mounting the wireless sensors in the desired location, verify the signal strength at the base unit by
performing the following procedure to verify the signal strength of each programmed wireless sensor. It may take
as long as 30 seconds to acquire the current signal strength.
Perform the following procedure to verify the signal strength of each programmed wireless sensor.
If No Data is displayed in place of bars, it indicates that recent signal strength information has not been received. If
this persists for 1-2 minutes without displaying any performance bars, it is a strong indication that your sensor is
placed out of range with the base unit.
If fewer than two bars are shown, it is recommended that the sensor be relocated to obtain a better signal. Refer to
the instruction sheet included with the wireless sensor for details on ensuring optimum signal strength.The wireless
environment can change throughout the day because of other activity in the vicinity. It is therefore important to
verify the signal strength by approximating the worst case scenario the RF signal may encounter.
F3 No Data is displayed until a signal is received and then the
signal strength is displayed as shown in the last screen.
