However, the charging time may vary by your working condition. A spare battery pack is provided as an accessory. We recommend keeping a fully charged spare battery at hand in order to replace the main battery when it is nearly Settled on the main board is a backup battery that keeps the mobile computer in suspension when the main battery is depleted. The backup battery is a 3.7V, 100mAh rechargeable Li-Polymer battery, and can retain data in the DRAM for 30 minutes when it is fully charged (as long as wireless modules on the mobile computer are inactive). It also keeps Wi-Fi and Bluetooth connections for about 30 minutes in suspend mode after the main battery is removed. The Wi-Fi and Bluetooth connections will resume right after the main battery is installed within the time period the connection is retained. The backup battery can be charged by the main battery or the power adapter, and takes approximately 4 hours to charge to full under the condition that it is always be charged except of power off and no external power. RTC battery is a 3V, 1mAh rechargeable SMT type Li-battery which takes about 12 hours to be fully charged. RTC retention will be maintained for at least 72 hours when the main battery is removed. 2.1. BATTERY Main Battery Spare Battery drained out. Backup Battery RTC Battery Warning:

(1) The battery cover must be secured in position with its latch locked.

(2) For a new battery, make sure it is fully charged before using.

Warning: Please do not perform a battery swapping before the mobile computers OS is ready. Removing the battery cover during powering up your mobile computer may cause system failure. 42 Using RS35 Mobile Computer Note:

(1) When main battery is removed, the system will stay in suspend mode for about 30 minutes. To prevent the system from being shut down without advance warning, please DO replace the main battery as soon as possible.

(2) Backup battery keeps the mobile computer in suspension when the main battery is depleted. Thus, to prevent data loss, DO NOT replace the main battery when backup batterys power is low. Please connect RS35 mobile computer with the external power source to charge it till the Low Sub Battery notification icon disappears from the status bar. Once the Low Sub Battery notification disappears, the main battery replacement could be proceeded. 43 RK25 Mobile Computer 2.1.4. POWER MANAGEMENT For any portable device, power management is a critical issue especially when you are on the road. Below are some tips to help you save battery power. Warning:

Using backlight, wireless connectivity, and peripheral devices while on battery power will substantially reduce battery power. Bring an additional main battery pack with you on the road. End wireless connections (such as Bluetooth transmission, wireless connection, NFC and GPS) which are not in use. Shorten the screen off time. See Screen Timeout Settings. Reduce the screen brightness level, see Screen Brightness. If you have had your Google account signed in on this device, you could turn off certain automatic data syncing of applications (such as Email, Calendar, and Contacts). Go to App Drawer | Settings

Expansion Slot The mobile computer is equipped with one SD card slot which can accommodate a micro SD card, a microSDHC (up to 32GB) or a microSDXC (up to 64GB-2TB). When choosing an SD card for best compatibility and performance with RS35, please make sure of the capacity you need. For the use of SDXC card, please use a new card and make sure it has not been used in other host devices (computers, cameras, or readers). CAUTION OF DATA LOSS When the main battery is removed or drained, the backup battery on the main board takes over to supply the mobile computer and keep it in suspension. A fully charged backup battery will retain the data in the RAM for 30 minutes. When the backup battery is drained out as well, the mobile computer will shut down, and only the contents of RTC will be retained (RTC retention will be maintained for at least 72 hours). All other unsaved data will be lost. If you want to put away the mobile computer for a couple of days, you should be aware that data loss occurs when the main battery and backup battery discharges completely. Therefore, it is necessary to backup data and files before putting away the mobile computer. 46 Using RS35 Mobile Computer 2.2.1.
