40.1 Battery Introduction
This monitor is designed to operation battery power when the mains power is not available. The monitor uses 
mains power as primary power source. In case of mains power failure, the monitor automatically runs on the 
battery power. 
• If the mains power fails and the monitor runs on the battery power, the display brightness 
automatically lowers to the dimmest. You can manually adjust the display brightness as required.
40.2 Battery Safety Information
 
• Keep batteries out of children’s reach. 
• Use only specified battery. Use of a different battery may present a risk of fire or explosion.
• Keep the batteries in their original package until you are ready to use them. 
• Do not expose batteries to liquid.
• Do not crush, drop or puncture the battery. Mechanical abuse can lead to internal damage and 
internal short circuits. If a battery has been dropped or banged against a hard surface, whether 
damage is externally visible or not, remove the battery from use and dispose of it properly.
• If the battery shows signs of damage or signs of leakage, replace it immediately. 
• Batteries should be charged only in this monitor.
• Extremely high ambient temperature may cause battery overheat protection, resulting in monitor 
shutdown.
• The lithium-ion battery has a service life of two years (for N22/N19) or three years (for N17/N15/N12/
N12C). Replace your battery when it reaches the end of its service life. Failure to replace the battery 
may cause serious damage to your equipment from battery overheating.
• Do not open batteries, heat batteries above 60 °C, incinerate batteries, or short battery terminals. 
They may ignite, explode, leak or heat up, causing personal injury.
• Lithium batteries replaced by inadequately trained personnel could result in a hazard (such as 
excessive temperatures, fire or explosion).
• Remove the battery before shipping the monitor or if it will not be used for an extended period of 
time.
• When the monitor runs on battery power, the monitor may automatically shutdown due to high 
power consumption if too many external modules are connected. 
• Use only the AC mains to power the monitor when the iView system is in use.
