This vehicle is equipped with a very simple control system:  

The Master is powered on and off by the vehicle ignition.  There is no need to turn the master off unless there is no need for power, inverter or Wifi in the vehicle.  To operate the emergency lights each switch for the primary lights and light bar need to be turned on individually.  The only switch for heat and AC in the patient compartment is located on the center console.  Temperature and fan speed are controlled at the rear control panel by the attendant seat. 


Siren operation is similar to most sirens and it is the crews responsibility to be familiar with its operation: 

The red switch is the siren master, rotate the dial to the desired wail setting.  The HORN/SIREN switch changes what the horn does on the steering wheel.  In Siren setting it changes the tone of the siren when the horn is pressed.  In Horn setting the vehicle horn will activate.  The switch should remain in horn setting when not driving emergency so the vehicle horn functions.


Find 120v shore power or a generator and plug it in.


Use block heater and glow plugs, never use ether on this engine.
