Thank you for contacting Conlog
Please see below steps to assist with RFCON error :
* Press the Back arrow on the keypad - this step is to refresh the UIU ( the device)
If it does not go back to the normal display
*Type # 80 # - this is to refresh the meter
The above steps will work better if you are outside the house because the meters uses the radio frequency connection
The above error will occur in instances of bad weather conditions or if there is load shedding or power failure
If the problem persists after trying the above you may contact the municipality or the service provider
