INSTRUCTIONS
This guide contains details on the use and operation of the INT2000 as a portable battery operated device. There is no instruction as to the permanent mounting and wiring of this unit in this guidebook. For permanent installation please refer to the AK-IN installation manual.
The INT2000 comes standard with one RI-1 radio interface cable that will interface a single Delcom AIR960 )or other land mobile radio) and this manual. A list of accessories for mounting and interfacing the INT2000 may be found on the last page of this manual.

BATTERY
The INT2000 may be powered in any of 3 different ways: Alkaline battery, rechargeable battery or external 12VDC (see AK-IN manual for permanent wiring.) Select battery ( not included), either a standard 9-volt alkaline or a 7.2 volt NiCad Install battery by removing 6 screws (4 on top & 2 on bottom) and slide the module from case. Insert battery and reassemble.

Note: The recharge jack on rear may be used to charge the INT2000 only when a rechargeable battery is used. Do not attempt to recharge the INT2000 when alkaline battery is used.

Time to recharge is generally 1 to 3 hours depending on battery condition. The WC-300 wall charger that comes standard with the AIR960 may be used. See rear page to order.

PREPARATION
Notice the pre-drilled & threaded holes on the case. These are for mounting the INT2000 to a hard surface. Mounting kits are available however if you chose to design your own mounting method make sure screw ends will not penetrate into unit causing shorts or other damage.

Pilot’s headset plugs into front and passenger into rear. Transceivers (com 1 & com2) may be plugged into rear connectors. Music or 3 nd
Receiver may be plugged into ‘AUX’ jack on front panel if desired.

NOTE: Any or all of the above connections may be wired to the rear 25-pin connector for permanent mounting. When the 25-pin connector is used the INT2000 may be also be interfaced to ARINC (aircraft standard) radios and optional passenger. Push to Transmit switch. Instructions and diagrams may be found at www.delcom.com.hk or in the optional AK-IN install manual.

FRONT PANEL

The first 3 top buttons control the receivers (push on push off) in any combination. The 4th button selects the voice filter for extra intercom clarity during high noise. Use the transmit selector to chose which radio to talk over and push the PTT (Push to Talk) button when you wish to transmit. The front mounted AUX jack permits you to plug in the 3rd top button select it, Pilot’s headset jacks, volume controls and on/off switch are also located on this panel.

REAR PANEL

Rear panel contains the passenger’s headset jacks, Com1 & com 2 radio inputs and the recharge jack. DB-25 connector is used only when INT2000 is permanently wired. If only one transceiver is connected the second (com 2) position may be connected to and additional audio.source.

OPERATION
Priors to engine start make sure headsets (or helmets) are comfortably fitted, radios are plugged in and all cords and hardware are secured. Set frequencies and volume levels while interfere with normal flight operation. A preflight routine where radios are set, tested & safety checked should become a regular habit. Switch off INT2000 and radios before engine start.

Turn power on to all radios and the INT2000. Select receiver(s) to monitor by pushing Com1, Com2 or AUX buttons in. Passenger also hears any audio selected by pilot. Pushing the button again (out position) de-selects the receiver.

Select either Com1 or Com2 as transmitter. To transmit over selected radio press the Push To Transmit (PTT) switch and speak in a clear normal voice. If passenger is speaking while pilot is transmitting the passenger’s audio is automatically muted. The sound you will hear while transmitting is your side-tone (your voice). Passenger will also hear your side-tone.
Set passenger’s intercom volume with the skinny (outer) knob and pilot’s with the fat (inner) knob. If you do not want to hear your passenger simply turn down pilot’s volume control, you will hear all radios and your passenger will still hear you.
For extra intercom clarity push filter button. Pressing this button will not affect radio reception and will charge only pilot/passenger intercom audio quality.
