  7. Charging the Battery • Memory effect is a phenomenon that causes a loss in battery capacity or voltage due to repetitive shallow discharging or long-term overcharging. • It is still recommended that you discharge your battery as much as possible before recharging it. Recharging after each shift is good standard practice. • Turn the radio off to ensure a full charge. • Note: Each EMS unit has a charger on board.

  23. Model W4 Mobile Radio

  24. W4 Mobile Radio Overview • While the Portable and Mobile radios are very similar in function, the actual use of the radios differs slightly in a few areas. • The following slides detail only those differences.

  28. Page Scan Sel Dir Call Zone and Mode Selectors Zone Arrows 7 B OPS Mode Selector • Change zones using up and down Zone Arrows. • Switch modes (A-O) using the Mode Selector.

  29.

  31. Units and Stations monitor the Dispatch Talkgroup (DISP TG). When dispatched on an incident units will be assigned to the Operations Talkgroup (OPS) unless assigned to an Incident Talkgroup (INC) by ECC. Dispatch and Operations Talkgroups

  32. Unit personnel should switch back to DISP (without advising ECC) to await their next incident. Dispatch and Operations Talkgroups

  33. Complex Incident Talkgroup Blocks • A complex incident is assigned to an Incident Talkgroup Block at the time of dispatch. The block contains three talkgroups for the Incident Commander to assign at his discretion. • ECC only monitors the first Talkgroup in the block. • The Incident Commander is responsible for monitoring the other Talkgroups assigned. • The Announce Talkgroup broadcasts across the entire block to communicating to everyone simultaneously.

  34. Multiple Talkgroup Blocks • The additional incident TG blocks function similarly. • The 7K-7M block is slightly different, as there are only two talkgroups plus one announce talkgroup. ECC often assigns 7K and 7L for business-related chit-chat instead of assigning incidents there. • Multiple sets of incident talkgroups can be assigned to a single very complex incident (e.g., train wreck).

  35. Zone 71 • Zone 71 contains the INC30 and INC40 series as well as the two chit-chat talkgroups (K and L).

  36. Zone 72: EMS • The CALL Talkgroup (72C) enables you to contact EMRC. (Note: Inform EMRC that you are using an 800 MHz radio.) • After contacting EMRC a Consult Talkgroup (CNSLT) will be assigned by EMRC.

  37. Zone 72: EMS • Zone 72 is the EMS default zone, where all EMS personnel begin. • The INC 50 and INC 60 series are also here.

  38. FDTA Channel and OPS Talkgroup • The Fire Department Talk-Around channel is O (across 7-71-72) and is for use when the trunked radio system is out of range. • This channel cannot be heard by ECC. • All radios should be set to scan FDTA so any possible vocal emergencies may be heard. • The OPS TG is repeated in the last position on the Talk Group dial so that it is easy to reach help - either end of the dial.

  39. 7-71-72N: What is VRS? • What: VRS is short for Vehicular Repeater System – All the Battalion Chiefs’ buggies have had repeaters installed in them and a few engines in border areas. • Why: With a VRS on-site, we can add to existing coverage by bringing a conventional channel to the repeater. • Where: The VRS may be used in areas where coverage is weak for portable radios, including near the river and (to some degree) parking garages and other underground structures. • When: The VRS won’t be needed very often, but it provides another tool for life safety.

  40. How Does the VRS Work? User switches to the VRS Channel (Repeat Mode)

  41. What Happens If You Can’t Reach the VRS? User Switches to Direct Radio Receives on Direct Mode Like the Scan Feature User Switches back to Repeat User Switches to Direct

  42. VRS Channel • Similar to FDTA, VRS is a simplex channel on which you can talk with other personnel on direct mode. • This channel cannot be heard by ECC. • This channel is only scanned by other radios on 7N, 71N, 72 N.

  43. How to Switch between Repeat and Direct Modes? • The concentric ring switch (the key pad lock/unlock ring) will enable you to toggle between direct and repeat modes • 7-71-72N (November) Concentric Ring Switch Repeat Mode Direct Mode

  44. How to Determine When to Use 7-71-72 N

  45. Zone 79: Hospitals • Zone 79 is for direct communication with the hospitals. • 79G is a Talkgroup shared by all of the hospitals.

  46. Zone 79: Hospitals • 79J and 79K are on the Montgomery County system (not DC’s radio system) and you are not required to be within DC’s range to use these talkgroups. • 79H allows communication with all in-county hospitals simultaneously. All Hospitals listed to the right of 79H are outside Montgomery County so the radio must be in coverage of the respective system. • Note: When switched to an out-of-County Talk Groups the radio is not visible to the County system.

  47. Zone 74: Major Incident Zone • Zone 74 is intended to be used on major incidents that involve numerous agencies and senior County leadership. • This zone would normally be used by senior County managers to coordinate multiple County, State and Federal resources.

  48. Zone 75: Coordination Zone • Zone 75 is used for intra-county coordination between agencies. • The Public Safety Talkgroups are available to all MCG public safety users (Fire/Rescue, Police, Sheriff and Corrections) via ECC. • The most common uses for Zone 75 involve 75 K-L-M, the Special Events Talkgroups. These are used for events such as the golf tournament and the fair.

  49. Zone MA: Council of Governments • Zone MA is the National Mutual Aid 800Mhz system. Any jurisdiction in Canada, the United States or Mexico that has 800Mhz capability can utilize these talkgroups to communicate with each other. • These talkgroups are monitored by a State level agency; Maryland is monitored by MEMA (Maryland Emergency Management Agency).

  50. Zones 76: Administrative and 73: Police • Zone 73 enables users to monitor the primary dispatch talkgroups of County and Municipal law enforcement agencies. • You can only listen to these talkgroups; the radios will not let you be heard.
