Battery Power
For portable use, there is a replaceable, built-in 1950mAh NP-120 Li-ion battery used by the TriCoder. This battery provides the main power for the scanner, display and all electrical circuitry. The internal battery should provide approximately 20 hours of continuous scanning, as well as retain the data in memory and provide for real-time clock operation for several months. Even though the battery can last for at least 6 months without use and without recharging, we recommend not keeping valuable data in the TriCoder any longer than necessary. Upload your data to the computer – do not risk losing data if you don‟t have to. Once you have uploaded, back up your data file on a disk or tape if the information is extremely critical. The TriCoder will detect low battery status. If the TriCoder detects low battery power it displays the following message for 20 seconds, then turns itself off to protect any data that may be in memory:
LOW BATTERY
UNIT SHUT DOWN
The TriCoder also has a battery life indicator that can be accessed in NON PORTABLE mode or during Data Collection. To display the remaining battery life of both the AA and the lithium battery (as well as the date, time and remaining
memory) press the STATUS key:
mm/dd/yy hh:mm nnnk BYTES FREE BAT - - - - 50%
Press the STATUS key again resume processing.
To change the Li-ion battery:
1.Turn OFF the TriCoder and unplug the 5-volt power adapter.
2.Remove the battery door on the back of the T5000 TriCoder, or the Handle on the LT500 model, by unscrewing the 2 screws holding the door or handle to the back of the TriCoder.
3.Remove the old NP-120 Li-Ion battery and insert a new one, making sure to orient the battery according to the diagram inside the battery holder. The positive (+) end of the battery should be facing toward the left of the bottom of the TriCoder.
4.Replace the battery door or handle and turn the TriCoder on using the ON/OFF switch.
Storing the TriCoder
Daily storage of the TriCoder does not require any special care. If the TriCoder is used on a daily basis or even monthly basis, the Li- ion battery should remain in the unit and be charged when low. If you are going to store the TriCoder for several months, charge the battery before putting the unit away to ensure all the settings and programs will be kept current. If the TriCoder is stored with a depleted battery for long term all of the programs and data in the TriCoder may be lost. For long-term storage (6 months or more) we recommend that you upload any stored data and programs.
If you remove the Li-ion battery for long periods of time you will also lose your data and custom programs. Make sure you have a backup of any important programs on your Host computer and you can easily restore the TriCoder programs.
