## Summary description

The Unify OpenScape CP400 is a wired IP phone featuring a 9.4 cm display with a resolution of 240 x 120 pixels. It supports up to 1000 phonebook entries and runs on a Linux operating system. Volume control is easily accessible via buttons, making it user-friendly. Ideal for office environments, this phone combines functionality with a sleek black design.

## Long description

The CP400 is a midrange business phone designed for budget-conscious professional users. The base unit includes 16 programmable function keys with a tri-color status indicator and supports expansion with up to two KM400 Key Modules, each adding 16 function keys. A paper label is used for key identification, keeping costs down while providing many programmable keys. The phone’s power-saving design allows connection of two key modules while remaining within PoE Class 2 limits.
Advantages
The CP400 provides a balance of affordability and functionality by offering numerous programmable keys and a tri-colored status indicator for clear line presence. Expandability with two KM400 modules lets users increase capacity without replacing the base phone. Use of a paper label for key names reduces replacement and update costs. Energy-efficient design supports additional modules without exceeding PoE Class 2 power allocation.
Key specifications
 Base unit programmable keys: 16
 Key module: KM400, adds 16 keys per module
 Maximum key modules supported: 2 (up to 32 additional keys)
 Status indicator: tri-color
 Key labeling: paper label
 Power over Ethernet: supports two key modules within PoE Class 2
How to use
Install the CP400 on a desk or mount as instructed by the manufacturer and connect it to the network with PoE or an appropriate power supply. Program the 16 function keys on the base unit through the phone’s configuration menu or management system. Attach one or two KM400 Key Modules to the phone to expand the number of programmable keys; label keys using the supplied paper labels. Ensure the total power draw remains within PoE Class 2 when using key modules.
Recommendations
For deployments requiring many programmable lines or busy reception desks, add one or two KM400 modules and verify PoE Class 2 availability on the switch. Use the paper labels for quick updates and low-cost maintenance.
