30 Psion Teklogix 7535 Hand-Held Computer Quick Start Guide
• Do not use in areas where static electricity is greater than
what the manufacturer guarantees.
• Keep batteries out of reach of children.
2.2.1 Battery Swap And Runtime
The 7535 battery will operate for ten hours under typical operating
conditions after a full charge. Typical battery life is 300 cycles or 2
years average use. A full charge is completed in 4 hours with a typi-
cal charge time of 1.5 hours.
Always switch the unit off before changing the battery. While the
battery is being replaced, the 7535 will save its current data for at
least 10 minutes.
2.3 The Keyboard
The 7535 offers two types of keyboard layouts – a 58-key keyboard
and a 36-key, large button keyboard.
The <BLUE> and <ORANGE> modifier keys provide access to
additional keys and system functions. These functions are colour
coded in orange and blue print above the keyboard keys.
2.3.1 Modifier Keys
The <SHIFT>, <CTRL>, <ALT>, <BLUE> and <ORANGE> keys
are modifier keys. Pressing a modifier key changes the function of
the next key pressed. For example, on a 58-key keyboard, a square
bracket is printed in orange print above the <4> key. Pressing the
<ORANGE> key followed by the <4> key displays a square bracket
rather than the number 4.
