The above holds true for units with *station identifiers*.

     For 200 & 300 units, the last two figures indicate the starting time of
     the unit's shift,

          eg. Nunawading 303 = Nunawading van on 3 pm - 11 pm shift. (12 hr
          clock.)


     A 5 as the middle digit of the numeric identifier indicates a sergeant.
     A 6 as the middle digit of the numeric identifier indicates a senior
     sergeant,

          eg. Glen Waverley 253 = Glen Waverley afternoon shift with sergeant
          on board.

          (N.B. The Dog Squad are not included in this system.)


Several variations in numeric identifier appear in Departmental callsigns.


Units attached to the Community Policing Squad may use a divisional callsign
with a 400 series, eg. BLACKBURN 463, (shift system applies,) or a
departmental callsign, eg. OPERATIONS 222 (shift system not applicable).

All Operations Department units employ the 400 callsign series. These are NOT
CRIME CARS!! Canine units are the only exception to this rule - see below.

     The Air Wing uses a 400 callsign series:

       40* = Ground vehicles
       41* = Fixed wing aircraft
       47* = Rotary wing aircraft - Squirrels
       49* = Rotary wing aircraft - Dauphins

               eg. AIR 402, (filling truck,) AIR 492, (helicopter,) etc..

     N.B.      [1] The air ambulance identifies on any service as AIR 495.
               [2] Rotary wing aircraft from other services identify with
               <service> 499, eg. PENINSULA 499 (Sth. Pen. Rescue Squad).

                    Aircraft Registration:   AIR 490/1      VH-PVF
                                             AIR 492/3      VH-PVK
                                             AIR 495        VH-PVA
                                             AIR 474        VH-PVM

               Operators can determine available aircraft from a backlit sign
               facing the consoles from the top end of D24.

     The Dog Squad use the 200 series, but do not follow the divisional shift
     system.

               eg. CANINE 278, CANINE 256, etc.; these are all dog squad
               units.



All Services Department may use any of the numeric callsign series.

     Radio Electronics Division TEST Callsign is COMMUNICATIONS 677.
     Mobile canteen is SERVICES 200, also known as CUP 'A' TEA 200.

     The Quick Response Vehicle (Communications) may also be known as the
     'QRV'. The callsign of this vehicle is VKC6. It is housed at Russell
     St..

(*) Note that the Special Operations Group use "SECURITY" identifiers when
operating 'clear', ie. non-DVP. When Public Security Groups are not allocated
major incident colour codes, they may also be found using SECURITY identifiers,
eg. on UHF channel 23 in Melbourne.
