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

Learning and Development

  • Assess how knowledge from this module will influence daily duties.
