  • Page 11: Accessory Connections

    ACCESSORY CONNECTIONS EXTERNAL SPEAKERS Use the External Speaker Connection on the back of the radio to connect your external speaker device. •If you plan to use an external speaker, choose a speaker with an impedance of 8 ohms. • The external speaker jack accepts a 3.5mm mono (2-conductor) plug.

  • Page 12: Antenna And Cable

    ANTENNA AND CABLE Radio Antenna is an optional additional purchase. Please visit our website for a list of compatible antenna. Radio performance relies greatly on the antenna and antenna cable! Before operating, install an efficient, well-tuned antenna and a high-quality antenna cable. Failure to do so will reduce transmit and receive range, radio call clarity, and can damage the radio.

  • Page 13: Installing The Antenna

    NOTE: proper antenna mounting, the radio range and quality may decrease. For the best range, only the Rugged Radios GMRS POINT5 antenna should be used. Specific installation requirements vary between vehicles. Use the following guidelines to install the antenna. The location of your antenna will significantly effect your radio’s performance! Mount the antenna as high on the vehicle as possible.
