CONNECTION

See in page 4

OPERATING

After starting the engine, put the ON/OFF switch to ON. Turn to OFF at the

end of each flight.

SQUELCH SETTING

Increase or decrease the squelch level (VOX) by turning the left knob.

Turn this knob to the right until the background noises can no longer activated the

VOX, while being able to activate easily with the voice.

You must speak loud and clear from the first syllable.

Squelch settings must be regularly changed depending on the ambient noises.

If you are unable to get a good setting is that the microphones of yours headsets

are not suitable to the ambient noise of your plane.

You must replace them for a noise cancelling microphone as our TITANE2 micro-

phone.

Your microphones can also be disturbed by the relative wind. In this case, use a

large microphone windscreen.

VOLUME SETTING

Increase or decrease the volume level by turning the right knob.

The intercom is power full, optimal setting is between noon and 3 o'clock.

By setting a highest volume, you may amplify the ambient noises that pass into

your microphones.

If you need a highest volume, is that your headsets are not noise cancelling

enough.

Volume control acts on the two headsets.

You can then change the volume of your headset by turning the volume knob on

your headset.

SWITCH NOISE K.

If you have connected the NK-A13 noise killer filter on back of the ICA-13 intercom, put

the NOISE K. switch to ON to activate the filter. Otherwise, this switch must remain on

OFF.

SWITCH MUSIC

If you have connected a MP3 player or other music source on back of the ICA-13

intercom, via the optional K13MU cord, put the MUSIC switch to ON to activate the

music, then to OFF to stop it.

If no music source is connected to your intercom, this switch must remain on OFF.

SWITCH PASS.

When this switch is turn to ON, your passenger hear all the on board communications :

intercom, VHF radio or Cell phone.

If you need to phone without your passenger hearing conversation, you can completely

isolate the passenger by putting the switch PASS. to OFF. ( his microphone and

speakers are disconnected)

VHF RADIO OPERATION

The VHF radio connected on the ICA-13 intercom is not voice activated. You must

push on the PTT button ( supplied apart) to transmit and release it after.

Receiving and transmitting radio are on the both headsets : to prevent your passenger

speaks while you are speaking with air control, you can isolate it by putting the switch

PASS. to OFF during your transmission. Likewise, if your plane is fitted with two PTT

button, make sure your passenger will not transmit accidentally.

NOTA :

The ICA-13 intercom is not sensitive to interference.

VHF radio may be sensitive to interference.

To prevent problems caused by interference, you must use shielded cable, you must

shield the spark plug cap, and you must make sure that your antenna is tuned, with a

good ground plane. If you still have problems despite all these precautions, we can

install our NF-A13 noise engine filter .

MUSIC OPERATION

The music level is automatically lowering when pilot or passenger speaks or upon receipt

of a VHF message.

AUXILIARY IN/OUT OPERATION

You need the optional K13AUX cord, fitted with a red RCA female plug and a black RCA

female plug.

The red plug is an audio output line level, for recording on-board communication.

The black plug is an audio input for receiving information or alarm from GPS or others

instruments ...
