   4.Advice for Charging Two-Way Radios

      For day to day battery charging, make sure all the battery contacts are clean, both on the

      charger and the rear terminals of the battery. If the contacts are dirty then the battery may

      not be detected by the radio charger and will not charge the battery correctly. Make sure 

      that you charge your radio batteries in a compatible charger otherwise you could

      potentially damage your battery and radio.

Push-To-Talk (PTT) is no longer a technology-driven term, it is an enterprise-wide capability. It enables teams to communicate instantly, reliably and productively together to improve business and elevate service. Today, broadband networks and devices are so ubiquitous, that any worker can be connected to any device in their pocket or on their desk with real-time communications through PTT. With interoperable broadband PTT, everyone can become part of the conversation without concern about which device or network they use.
