    ® FLASHport The ASTRO APX 7000XE radio utilizes Motorola’s FLASHport technology. FLASHport makes it possible to add software that drives the radio’s capabilities both at the time of purchase and later on. Previously, changing a radio’s features and capabilities meant significant modifications or buying a new radio.

    Chapter 2 Basic Maintenance This chapter describes preventive maintenance and handling precautions. Each of these topics provides information vital to the successful operation and maintenance of your radio. General Maintenance In order to avoid operating outside the limits set by the FCC, we recommend that you align the ASTRO APX 7000XE radio’s reference oscillator every time the radio is taken apart, or once per year, whichever comes first.

    Sec 2: 2-2 Basic Maintenance: Handling Precautions • The APX 7000XE radio has a vent port that allows for pressure equalization in the radio. Never poke this vent with any objects, such as needles, tweezers, or screwdrivers. This could create a leak path into the radio and, the radio’s submergibility will be lost.
