Selection of transmission level specifies the maximum output power level. The maximum value is 3 dBm. By
selecting the higher transmission levels communication over longer distances can be achieved, but the noise
and disturbance levels will increase. We recommend that you try your system with the factory default setting
first. If disturbances are detected (faulty characters or other errors) decrease the power level step by step.
If the transmission fails because of a weak signal the transmission level can be increased step by step until a
satisfactory transmission quality is achieved. Please note that levels above –9 dBm are not allowed on PTT
networks and can only be used on private wires!
