Editing Psion Revo Handbook (section)

== What it settles ==

* Psion's specification (p. 206): 157 × 79 × 18 mm; 200 g; 480 × 160 greyscale reflective display; 8 MB or 16 MB ROM depending on model; 8 MB RAM; ARM 710T core at 36.864 MHz; two 650 mAh AAA NiMH cells; 6 V DC ± 10 %, 500 mA mains adaptor; 53-key keyboard; operating temperature +5 to +40 °C, storage −10 to +40 °C.<ref name="hb-206">''Revo Handbook'', p. 206, Specification.</ref>
* Charging and battery life (pp. 17-18): a fast charge followed by a trickle charge taking about 4½ hours to reach 100 %, with the red charging light going out during the trickle stage; a first full charge of up to 6 hours; about 12 hours of use; information kept for about 2 weeks after the battery runs down, and for 6 weeks when fully charged and switched off.<ref name="hb-17">''Revo Handbook'', pp. 17-18, The battery & charging.</ref>
* The care chapter advises recharging regularly and keeping the battery topped up, and says the battery performs better in the long term if it is not regularly run down completely before recharging. A switched-off Revo uses about 1 % of its charge per day.<ref name="hb-198">''Revo Handbook'', p. 198, Prolonging battery life.</ref>
* Resets (p. 202): soft reset through the hole marked 1; hard reset by pressing both ends of an unfolded paper clip into holes 1 and 2 together, then pressing Esc (On) twice. One beep on switching on confirms a hard reset; two beeps mean only a soft reset took place.<ref name="hb-202">''Revo Handbook'', p. 202, How do I reset my Revo?</ref>
