4 Psion Teklogix CH4000 Quick Reference Guide
2. CH4000 Introduction
Important: To preserve battery integrity, the desktop docking
station will proceed with a charge only when the
battery temperature falls between 0°C and 40°C
(32°F to 104°F).
The CH4000 desktop docking station is a desktop model
designed to:
• Fast charge the internal battery.
• Fast charge the spare battery pack (see Figure 2.1 on page 5).
• Supply Type A and Type B USB connectivity to the Ikôn (see
Figure 3.1 on page 7).
The desktop docking station provides sufficient power to concur-
rently support all the above functions.
The CH4000 uses careful charge algorithms designed to maximize
battery life while ensuring the shortest possible charge time. The
charger supports proprietary Psion Teklogix Smart Batteries and
handles a range of voltages and charge algorithms. See the appropri-
ate Ikôn user manual for more information regarding battery capac-
ity, charge times and battery life, for the Ikôn battery. See “Charging
The Spare Battery” on page 6 for spare battery charge information.
