Compatibility & Buying Information
Exact Set: This page is for Mitel part number 51310674, the 712dt DECT Set. The Set configuration includes the handset and desktop charging solution.
Requires DECT Infrastructure: The 712dt is a system DECT handset and does not operate as a standalone cordless telephone. It must be registered to compatible Mitel SIP-DECT infrastructure and supported DECT base stations.
Entry-Level 700d Model: Mitel identifies the 712dt as the entry-level general-purpose model in the 700d family. Customers needing additional Bluetooth, vibration, alarm, or worker-safety capabilities should compare the higher 700d models.
712dt vs. 722dt: The 712dt does not provide Bluetooth, vibration mode, a programmable hotkey, or microSD support. The 722dt adds those higher-level mobility features.
712dt vs. 732d / 742d: The 732d and 742d add rugged IP65 construction and worker-safety sensors such as man-down and no-movement detection. The 742d is also the ATEX hazardous-area model. The 712dt is intended for normal professional environments rather than industrial or explosive-risk locations.
BioCote Antimicrobial Plastics: The handset is manufactured using plastics treated with BioCote antimicrobial technology. The treatment is intended to inhibit the growth of certain microorganisms on treated surfaces but does not replace normal cleaning, sanitation, or hygiene practices.
IP44 Protection: The handset provides IP44 enclosure protection for normal professional environments. It should not be treated as equivalent to the IP65 protection provided by the rugged 732d and 742d models.
Wired Headset Only: The 712dt provides a standard 3.5 mm headset connection but does not contain the Bluetooth interface used by the 722dt, 732d, and 742d.
USB-C: The USB-C connection supports charging and supported configuration or data-transfer functions. Mitel lists approximately 5 hours for a full USB charge compared with approximately 2.5 hours in the desktop charger.
Battery Runtime: Mitel lists up to approximately 15 hours of talk time and 105 hours standby for North American operation with a fully charged standard battery. Actual battery life varies with radio conditions, display usage, volume, and operating conditions.
Display Documentation: Mitel's current product page and 712dt marketing datasheet list a 240 × 320 display, while the Release 9.2 user guide lists 220 × 320 in its technical table. This page follows the current product and datasheet specification of 240 × 320.
Best Fit: Mitel 712dt 51310674 is best suited to offices, healthcare, schools, hospitality, retail, shared workspaces, and other everyday enterprise environments that need reliable SIP-DECT mobility, a color display, wired-headset support, antimicrobial-treated surfaces, and a complete desktop charging solution.
