location of the copilot's instrument panel for control of the ELT
from
the flight crew station.
The annunciator, which is in the center of
the rocker switch,

CABIN FIRE EXTINGUISHER
A
portable
HaIon
1211
(Bromochlorodifluoromethane) fire
extinguisher is standard and is installed on the floorboard
near the
pilot's seat where it would be accessible in case of fire. The
extinguisher has an Underwriters Laboratories classification of 5B:C.
If installed, the extinguisher should be checked prior to each flight to
ensure that its bottle pressure, as indicated by the gauge on the
bottle, is within the green arc (approximately 125 psi) and the
operating lever lock pin is securely in place.
To operate the fire extinguisher:
Loosen retaining clamp(s) and remove extinguisher from
bracket.
Hold extinguisher upright, pull operating ring pin, and
press
lever while directing the discharge at the base of the fire at the
near edge. Progress toward the back of the fire by moving the
nozzle rapidly with a side to side sweeping motion.
