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.
