HP - HPP-85X07AA

High-Resolution Display: Integrated 5.0-inch, 480 x 800 pixel backlit colour LCD screen. The digital display eliminates paper insert labelling and auto-populates directory data directly from the host phone. 

Programmable Key Matrix: Features 30 physical line keys configurable across 3 pages, providing access to a maximum of 90 programmable functions per module (such as line registrations, speed dials, or direct station selection). 

Dual-Colour Status Indicators: Each key features an integrated bi-colour (red/green) LED. This provides immediate visual feedback for Busy Lamp Field (BLF) monitoring, active calls, ringing lines, or parked sessions. 

Plug-and-Play Connectivity: Connects directly via the host phone's USB port for seamless data transfer and configuration sync. No secondary network provisioning is required. 

Bus-Powered Architecture: A single EM50 module runs entirely on the host phone's power supply (via PoE or standard AC adapter). 

Daisy-Chain Expansion: For ultra-high volume routing environments, up to two EM50 modules can be connected to a single VVX 450 phone. 

Operational Efficiency: Minimizes dropped calls and reduces routing latency by providing single-button transfers, parking, and speed dials. 

Presence Monitoring: Empowers administrative staff to track real-time extension availability across the office floor, preventing blind transfer errors. 

Maximizes Hardware Investment: Extends the lifecycle and capability of standard VVX 450 desktop units, transforming them into full-scale attendant consoles without requiring a complete hardware overhaul.
