You can power your scanner using three alkaline or rechargeable AA batteries. There is no switch for the battery type. Using non-rechargeable batteries, select "No" at the Battery message when connecting the USB cable. 1. Install 3 AA batteries, matching the polarity symbols (+ -). 2. Replace the cover. When Battery icon flashes and the scanner beeps every 15 seconds, replace or recharge the batteries.
本机可用 3 节 AA 碱性或充电电池供电，机身上没有电池类型开关。若使用不可充电电池，连接 USB 线时 在 Battery（电池）询问界面选择 "No"（否）。1. 按仓内 +/- 极性标识装入 3 节 AA 电池；2. 装回电池 盖。当电池图标闪烁且每 15 秒蜂鸣一次时，请更换或充电。
充电电池的使用 / Using Rechargeable Batteries
You can also use three rechargeable batteries to power your scanner. Before you use rechargeable batteries, you must charge them. The scanner has a built-in circuit that lets you recharge batteries while they are in the scanner. If the USB cable is connected to the scanner, or batteries are installed in the scanner when an USB cable is connected, the scanner will check the battery condition. When the scanner is turned on, the scanner does not charge the batteries. When the scanner is turned off, the scanner will charge the batteries. The scanner displays "Normal Charging" while charging the batteries according to the Set Charge Time setting. Caution: If the scanner gets too hot while charging, it will turn off automatically. If the batteries are not installed, "No Battery" is displayed.
充电流程：机内有内置充电电路，可将电池留在机内充电。连接 USB 线（或装电池后再连 USB 线）时，扫 描机会检测电池状态：开机状态不充电，关机状态才充电。充电期间屏幕显示 "Normal Charging"（正常 充电），充电时长按 Set Charge Time 设定执行。注意：充电中若机身过热将自动关机；未装电池时显示 "No Battery"（无电池）。
All of the information contained in the scanner is stored on a microSD card supplied with the scanner. This includes Favorites Lists and all the radio settings.
扫描机的全部数据（收藏列表及所有无线电设置）都存储在随机附带的 microSD 卡上。
FAVORITES LISTS · 收藏列表
Because the memory is based on the Radio Reference database we now have a different order of organization not like banks and channels in traditional scanners, but more like Dynamic Memory Architecture. You can now use Favorites Lists that follow RR database structure of Systems that contain Departments that hold the Channels (conventional frequencies or IDs) and then there are Sites to hold just the trunking frequencies. If you are familiar with DMA (Dynamic Memory Architecture) scanners, think of departments as being like channel groups. Favorites Lists will allow you to store channels you find when you are scanning from the full database (the easiest way). They can contain channels from trunking systems and conventional systems. You can also manually add systems, (not single sites), departments and channels into Favorites Lists from the database as well as program new systems, departments, sites, and channels with the Sentinel software. You can save up to 256 different lists in the scanner (and software) and associate them with any or all of your profiles. You can monitor one or more lists at a time and/or the database. You can also export you lists to a file to share them. Deleting a profile will not delete the lists associated with a profile. However, deleting a Favorites List will delete it from all profiles.
本机内存不再采用传统扫描机的"信道组（Bank）+ 信道"模式，而是类似动态内存架构（DMA），沿袭 RR 数据库的层级结构：收藏列表 → 系统（System）→ 部门（Department）→ 频道（Channel，常规 频率或集群 ID）；站点（Site）则专门存放集群频率。熟悉 DMA 扫描机的用户可把"部门"理解为"信道 组"。收藏列表既可容纳集群系统频道，也可容纳常规系统频道；既可从数据库（美版）添加系统、部门、 频道，也可用 Sentinel 软件全新编程系统、部门、站点、频道。全机最多可存 256 个列表，可关联任意配 置档案；可同时监测一个或多个列表；列表可导出为文件分享。删除 Profile 不会删除其关联的列表；但删 除某个收藏列表会把它从所有 Profile 中删除。
SYSTEMS · 系统
Systems will hold all of your Sites, Departments, and Channels.
系统承载其下所有的站点、部门和频道。
TRUNKING SITES · 集群站点
Inside systems are trunked sites hold the trunking frequencies for any trunking system and any band plan information needed. You will need at least one site for each trunked system and some systems can have several sites.
