Battery-Powered Units
Battery-powered TechTerms come equipped with a rechargeable Nickel Metal Hydride
(NiMH) battery that has exceptional charge life without the “charge memory” characteristic
of conventional nickel cadmium batteries. Partially discharged batteries or extended periods
with the charger left connected will not adversely affect battery life or performance.
Operating time on a full charge is up to 40 hours, depending on use. The time required for a
full charge depends on the initial state of the battery. With the terminal off, this time should
not exceed eight hours. Battery-powered TechTerms can also operate on six AA alkaline
batteries.
Battery-powered TechTerms also have a low battery indicator, which indicates that there is
approximately one hour of operating power remaining. A built-in power saver will turn off
battery-powered TechTerms after ten minutes of inactivity. Any key press or character
received by the TechTerm will reset the power-saver timer.
To turn on battery-powered units, press the On/Off switch. The terminal should turn on and
a blinking cursor should appear on the display. If the terminal does not turn on, refer to the
Troubleshooting section of this manual for help.
Charging the Unit
Because the internal battery charger senses several conditions, including temperature, you
should charge the unit away from any known or potential heat sources. Units exposed to
temperatures in excess of 90 degrees Fahrenheit during the charge cycle may experience
incomplete charging and reduced operating time per charge.
To recharge the Nickel Metal Hydride (NiMH) battery pack, plug the Two Technologies’
power supply/battery charger (Part # 13799) into the PCAT adapter and then plug the power
supply/battery charger into a 120 VAC 60 Hz power outlet.
Changing Batteries
To change batteries:
1.
With the unit face down, pull the battery cover retaining clip up from its recessed
slot and turn the clip in a counter clockwise motion.
2.
Lift the cover up and remove the batteries. If the unit contains a battery pack, use the
tab on the battery pack to lift up and then out.
