Yealink EXP43 Color Expansion Module
PRODUCT DESCRIPTION
Yealink EXP43 Color Expansion Module (EXP43) - 2 Years Local Warranty
4.3-Inch Color Screen with 60 DSS Keys
The Yealink EXP43 pairs a 4.3-inch 272 x 480-pixel backlit color display with 20 physical keys, each fitted with a dual-color LED. Three page views switch instantly via 3 independent illuminated control keys, giving you up to 60 programmable keys per module for lines, speed dials and busy-lamp-field (BLF) monitoring — every key clearly labelled on screen, with status visible at a glance.
Built for Yealink T43U, T46U and T48U IP Phones
The EXP43 is designed for the Yealink T4U series and applies to the SIP-T43U, SIP-T46U and SIP-T48U. It connects over a USB 2.0 port for data in and out and sits neatly beside the phone on a stand with 2 adjustable angles, matching the handset's desk profile for a clean, professional setup.
Daisy-Chain Up to Three Modules — 180 Extra Keys
Up to three EXP43 modules can be attached to a single T43U/T46U/T48U, scaling to as many as 180 additional keys. A single module draws power from the phone; when two or three modules are connected, an external 5V/2A power adapter is used. Maximum power consumption is just 1.5 W.
Reception-Desk Ready for Singapore Offices
For receptionists, operators and executive assistants in Singapore businesses handling high call volumes, the EXP43 turns a T4U desk phone into a compact attendant console. SourceIT supplies the EXP43 from local stock with a GST invoice and 2 years local warranty support.
