Overview
Enhanced System Design
The DX340ES is a slightly modified version of the DX300ES that includes better RF filtering, lost packet concealment and enhanced 7kHz wideband audio.
Hands-Free, Full-Duplex Communications
Each base can support up to four full-duplex or 12 half-duplex WH340 headset users. By linking four base stations together, up to 16 full-duplex or 44 half-duplex WH340 users can be in communication.
Rugged and Lightweight Design
The WH340 has a rugged, reinforced casing and long lasting keypads with no mechanical switch. The WH340 has a lightweight, balanced design and wire-free steel headband for all day comfort.
Long Battery Life
Using the BAT50 Li-Ion battery, the WH340 has up to 12 hours of battery life. The AC50 charges up to 4 BAT50 batteries at a time and includes storage slots for 4 additional batteries. Charging time is 2.5 hours.
