    Study Notes

    Airwave Communication System

    • Officers must switch back to their assigned talkgroup to maintain contact with control and ensure safety, especially when crossing division borders.
    • Inability to transmit over ongoing communications requires officers to wait for others to finish speaking before sending messages.

    Direct Mode Operation (DMO)

    • DMO is necessary in scenarios of poor Airwave coverage, total system failure, or urgent incidents in low reception areas.
    • Activating the emergency button triggers alarms at control and on other terminals in the talkgroup, enabling communication even if the device is dropped or inaccessible.

    Emergency Button Functionality

    • Holding the Emergency Button for 1.5 seconds activates 'Hot Mic' for hands-free communication with the control room for ten seconds.
    • The emergency function overrides ongoing transmissions, allowing the officer to communicate their location and emergency nature.

    Text Messaging Capabilities

    • Airwave terminals allow sending and receiving text messages between terminals, but cannot contact personal mobile phones.
    • To send a message: select ‘Menu’, then ‘Messages’, create a new message, type, and send to the specified address.
    • To receive a message: navigate to ‘Messages’ and access the ‘Inbox’ for new and stored messages.

    Cleartone Lynx CM9000FP Vehicle Unit

    • Vehicles have a Cleartone terminal which operates on the same Airwave system but appears different from personal Airwave terminals.
    • Local training is provided for the use of vehicle-mounted communication units.

    Operational Guidance

    • Familiarize with local policies on Airwave terminal usage.
    • Recognize the advantages and functions of the Airwave system, including:
      • Talkgroups and Primary Talkgroups
      • Trunked Mode Operation (TMO) and Direct Mode Operation (DMO)
      • Emergency Button
      • Point-to-Point communication
      • Transmit inhibit feature
      • Telephone calls and text messaging options
