Study Notes
Radio Communications
Considerations
- When calling another radio, the called radio will be pulled off its talkgroup for a time and will not hear any talkgroup audio, including dispatch calls.
- Electronic devices should be discontinued and turned off within 100 yards of suspected explosive devices or in construction areas with warning signs.
Radio Usage Guidelines
- Keep radio volume at an audible level when in-service and remain attentive to calls.
- Be professional and refrain from using uncivil, harsh, or vulgar language.
- Confine radio transmissions to official police business and information.
- Keep car-to-car transmissions at a minimum and limit them to official police business.
- Always acknowledge radio calls from the dispatcher by giving east/west street locations first and complete radio numbers.
- Identify yourself by complete radio number when using the radio to communicate with other members.
- Advise the dispatcher of any change in the status of a call, including change of location.
- Advise the dispatcher via radio when 10-23 on all calls when the Mobile Data Computer (MDC) is not available or cannot be used.
- Notify the dispatcher prior to leaving their assigned talkgroup.
Radio Terminology
- I-Call: A specific type of radio transmission between two radios through the radio system where a talkgroup is not used.
- P25 Conventional: A digital form of conventional mode where radio transmissions do not pass through the radio system and are typically not capable of communicating with dispatch.
- Radio Identification Number (RID): A number assigned to each radio, sent every time Push to Talk (PTT) is pressed, and can be decoded by receiving units.
- Repeater: Receives a signal and re-transmits it, usually with higher power and from a better location, to provide a greater communication range.
- Simplex or Direct: A conventional mode where radios communicate with each other directly, transmit, receive, and operate on the same frequency and with no repeater or other device in between.
- System or Zone: The name of a set of talkgroups or channels.
