Chapter 1 — Using the Computer Reading Distances Typical reading distances are done in an office environment using office lights (4 lux). Minimum distances are measured in the dark (0 lux). Both reading distances are provided in respective scan engine integration guides. Contact your Intermec representative for more information. The minimum standard reading distances for CN3s built with integrated scan engines are shown below.
Chapter 1 — Using the Computer Using the Batteries The CN3 uses replaceable Lithium-Ion (Li-ion) batteries. Standard packs have 8.1 Watt hours capacity and extended packs have 14.8 Watt hours capacity. You must fully charge the battery before you can use the CN3. When you change the battery, a super capacitor maintains your status, memory, and real-time clock for at least five minutes. The battery used in this device may present a fire or chemical burn hazard if it is mistreated.
Chapter 1 — Using the Computer The charge/operating power can be applied to the CN3 using an AC wall adapter, a magnetic card reader snap-on, a single dock with ac adapter or auto-lighter adapter attached, a multidock, either charge-only or Ethernet, or an auto lighter adapter. For information on these accessories, see “Accessories for the Computer” on page 190. Maximizing Battery Life Note that batteries are chemical devices.
Chapter 1 — Using the Computer To install the battery, insert the tabs on the charged battery into the CN3 and snap the battery into place. Checking the Battery Status The Battery Status LED above your CN3 display, as shown in the following illustration, indicates the status of your battery. See the following table to understand the meanings of the lights emitted from the LED. Battery Status LED Steady Green Battery is more than 95% charged and CN3 is on a charger. Blinking Red Battery is low.
Chapter 1 — Using the Computer Note: The Backup battery option shown in the Battery tab refers to the super capacitor used by the CN3 to store energy. Understanding the Low Battery Warnings When the battery charge is getting low (approximately 6.4 to 6.5V), you will receive an audible alert and an initial pop-up “Main Battery Low” warning message. If the warning is not dismissed, it is followed by another audible alert and a second pop-up “Main Battery Very Low” warning message.
