Introduction: Battery 1-5 Text Area This area displays menus, messages, unit names or IDs, and other information. Display Options Two display options appear at the bottom of most screens. You select a display option by pressing the below it. Menu Key Many features provide context-sensitive menus that let you access related features and actions. the icon appears any time a context-sensitive menu is available. Press to access the menu. Menus and Lists Your radio's features are arranged in menus, submenus, and lists. To access the items in a menu or list, scroll using either the or keys. Battery WARNING: To avoid a possible explosion: DO NOT replace the battery in any area labeled "hazardous atmosphere." DO NOT discard batteries in a fire. Battery Life Your radio uses a rechargeable Lithium Ion (Li-Ion) battery. Based on 5% transmit, 5% receive, 90% standby (standard duty cycle): • NNTN4655 Li-Ion; Up to 19 Hours • SNN5706 Li-Ion; Up to 14.5 Hours Battery life is determined by several factors. Among the more critical are the regular overcharge of batteries and the average depth of discharge with each cycle. Typically, the greater the overcharge and the deeper the average discharge, the fewer cycles a battery will last. For example, a battery which is overcharged and discharged 100% several times a day, lasts fewer cycles than a battery that receives less of an overcharge and is discharged to 50% per day. Further, a battery which receives minimal overcharging and averages only 25% discharge, lasts even longer. WARNING: Care should be taken to avoid external short circuiting of the battery. A sustained high-rate discharge (for example, a paper clip placed accidentally across the battery contacts) may permanently damage the battery, void the battery warranty, and create a burn or fire hazard. Motorola batteries are designed specifically to be used with a Motorola charger and vice versa. Charging in non-Motorola equipment may lead to battery damage and void the battery warranty. The battery should be at about 77°F (25°C) (room temperature), whenever possible. Charging a cold battery (below 50° F [10°C]) may result in leakage of electrolyte and ultimately in failure of the battery. Charging a hot battery (above 95°F [35°C]) results in reduced discharge capacity, affecting the performance of the radio. Motorola rapid-rate battery chargers contain a temperature-sensing circuit to ensure that batteries are charged within the temperature limits stated above. WARNING: Do not attempt to change or charge the battery in a hazardous atmosphere. To charge the battery, place the battery (with or without the radio) in a Motorola-approved charger. 9980384R89-O February 15, 2005
