8.2. Connection problems
If you are seeing "No Comms" errors, follow these steps:
If the "No Comms" is persistent:
• Check that the proper serial number is entered into the
AI SetupT1/T2 Setup menu�
• Ensure the transmitter is turned on, by connecting it
to a first stage and turning on the tank valve. Applying
high pressure > 50 PSI (3�5 Bar) is the only way to turn
on the transmitter. The transmitter will power off after 2
minutes of no pressure�
• Bring the handset within range (3ft / 1m) of the
transmitter� Having the transmitter too close (less than
2 inches / 5 cm) can also cause communication loss�
If the "No Comms" is intermittent:
• Search for sources of radio frequency (RF)
interference, such as HID lights, scooters, or photo
flashes. Try eliminating such sources to see if this
solves the connection problem�
