Polmar transceiver has been factory preset and in most cases the transmitted audio should
be correct. A 15 pin connector is supplied for connection to the electrical system and mi -
crophone/speaker.
Notes to the installer/user.
This is a 12-24Vdc radio, voltages greater than 33V voltage will severely damage it.
When making adjustments to the transmitter, ensure that you are not on an occupied
channel.
Do not transmit on 121.500MHz, as this is the international distress frequency.
Do not transmit into an unterminated antenna line as a suitable antenna must be con
-
nected. Transmitting without being connected to an antenna may damage the radio.
Ensure that the supply voltage is regulated and does not fall below 11.7 Vdc or exceed
31 Vdc.
The transceiver is not waterproof. Do not allow it to get wet.
Speaker impedance must be either 4 or 8 ohms (4 ohms preferred) at 5 watts.
Use of electret microphones highly recommended.
