D
C ) Operating of the ELT in the portable mode
After forced landing or aircraft accident it may be desirable to use the transmitter in the
portable mode. Various reasons may necessitate this, such as:
- Broken or disabled whip antenna:
⇒
REMOVE ELT FROM A/C
- Severed whip antenna cable:
"
- Danger of fire or explosion in aircraft:
"
- Temperature extremes in aircraft:
"
- Poor transmitting location:
"
D ) Removal of ELT from aircraft:
N O T E
Accomplish as quickly as possible to resume or start emergency signal.
1. Turn the unit master switch to
"OFF"
-position.
2. Disconnect whip antenna cable and remote switch cable.
3. Turn winged nut on rear bracket clip to release transmitter (remove ELT).
4. Remove the telescope antenna from the stowage clips and insert into the ANT recepta
cle. Extend antenna fully.
N O T E
Do not use the "AUTO" position!
5. Turn unit master switch to "
ON
" position.
E ) Best transmission may be obtained by:
- Keeping antenna vertical.
- Standing transmitter upright on a metallic surface, such as an aircraft wing or stabilizer.
- If terrain prohibits good transmission (such as a deep valley or canyon) place the transmit-
ter on the high ground or hold in hand on high place.
- Stay close to the downed aircraft.
- In freezing weather, place transmitter inside jacket or coat to keep the battery warm. Let
the antenna extend outside jacket.
- Keep all moisture and ice away from the antenna connection and the remote connector
pins.
N O T E
Do not turn pointer portable "OFF" - even by night as search aircraft may be enroute
around the clock. Even when you have been sighted or think you have, the spotting
aircraft may not be able to relay an accurate or timely "fix" on your position without
a continued signal.
Only when the rescue team appears discontinue signalling by using the "OFF"
position.
