Becker AR3201 Installation Instructions

Installation Instructions for Becker AR3201, comm radio harness:
READ ALL THE INSTRUCTIONS BEFORE BEGINNING INSTALLATION.
1) 'AR3201 SPKR': Solder center conductor to (+) tab on a 4 ohm, 5-watt speaker. Solder
the black shield wire to the (-) tab.
2) 'AR3201 PTT = Blu, AR3201 Mic Hi = Wh, AR3201 Mic Lo = Blk': All conductors of this
multi-conductor wire go to the mic jack. Solder the blue striped wire to the push-to-talk
tab, which is the 'tallest' contact on the jack. Solder the plain, white, wire to the mic hi
tab, which is the 'shorter' contact on the jack. Solder the black shield wire to the ground
tab corresponding to the jack's threaded portion. Be aware that the AR3201 uses an
internal jumper to choose between standard and dynamic mic output. See the
manufacturer's manual to see if this jumper needs to be moved to match your
installation.
(*) If installing a push-to-talk switch, use the single conductor, shielded wire, marked
'AR3201 PTT'. Solder the center conductor and shield wire to the tabs of a
customer-provided, push-to-talk switch. Activating EITHER the remote PTT switch OR
the PTT switch on a mic assembly connected to the mic jack will allow voice
transmission over the radio.
3) 'AR3201 LTS': If you wish to activate the backlight on the radio face, solder the 'Light'
wire to one tab of the normally open contacts of a customer-provided switch. Solder a
+12 VDC wire to the other contact. When the contacts close, the backlight in the radio
face will be lit. If desired a dimmer pot may be used in place of the switch. If no lights
will be used, cap and stow this wire.
4) 'AR3201 GND': Attach this twisted pair of wires to, either airframe ground or a
dedicated avionics ground. This may be accomplished with solder or by installing a ring
terminal and using the appropriate hardware.
5) 'AR3201 PWR': Install an appropriately sized ring terminal and attach it to the 'load'
terminal of a 12-volt, 3-amp circuit breaker. * ALWAYS check that the power supplied to
the radio is correct as per the manufacturer's requirements. *
6) Connect the 15-socket connector to the back of the radio with the slide locks.
