  • Page 63 • In cases where a cellular phone tower is nearby, certain combinations of cell frequencies may cause interference. In some cases, changing channels may have no effect. Please call 3M FST Communications Products Technical Service (800-328-0033 press 2, 4) in these cases.
  • Page 64 475 MHz These licensed units must compete with other radios of local businesses that may have up to 5 watts of power. However, to maximize battery life, power is restricted to less than 5% of this figure. This makes them susceptible to interference from these high-powered radios operating nearby. In addition, there are mobile radios within this frequency range on service trucks, ambulances, and inventory systems.
