Power supply tips
∙Device configuration data is automatically saved when batter- ies are being replaced.
∙When the batteries are weak, it is harder to control devices from a distance.
∙Be sure to replace rechargeable batteries if they have been used for longer than two years or have been recharged over 500 times; extended use can lead to a danger of leakage.
Battery low icon
When the battery charge is low, the battery low icon 
is displayed in the information screen. You should recharge the batteries or replace them with new ones immediately.
Battery life and backlight function
Battery life depends mainly on the use of the backlight function. Your batteries can last up to three months or only a few days if you con- stantly use the backlight. To prolong battery life you should use conservative settings for the backlight (short “on period” and “auto on” only at a low ambient light level).
