Appendix B: Operating Environment

B.1 Operating Temperature
The recommended operating temperature is from -30°C to +60°C (-22°F to
+140°F).
Below -30°C (-22°F) the LCD screen may become damaged. Prolonged
exposure to temperatures above 60°C (+140°F) may damage the unit. Do
not exceed +70° (+158°F).
Recharging should not be performed outside the range 0°C to 40°C (32°F
to 104°F nominal), so outside this range charging is disabled by the BIOS.
Battery capacity and RTC (clock) accuracy are adversely affected by
operation or storage at the temperature extremes.
B.2 Humidity
The MP2500 is designed to operate in conditions of up to 90% relative
humidity. It has an internal desiccator and a visual indicator shows any
water ingress (by changing from blue to pink).
B.3 Waterproofing and Dustproofing
The MP2500 is designed to resist the ingress of water and dust, to standard
IP65 (BS 5490). Factory pressure testing assures that leaks do not occur.
Sealing characteristics can be impaired by non H approved
USKY
maintenance or modifications, or by impact damage. The commonest
cause of failure is a loose battery cap.
The MP2500 will withstand exposure to rain without ingress of water.
If water is trapped in the keyboard area it may lead to progressive keyboard
failure, exhibited by "over sensitive" or "latched on" keys. To avoid this,
drain the unit by storing it vertically in a warm place. MP2500 should
recover when dry. Forced drying is not recommended.
