Design for Retail, Hospitality and Healthcare
In today’s retail and healthcare world, more and more employees need to free their hands to take notes, serve dishes or carry things. WHM621 with Charging Cable is a DECT headset working with W70B DECT base/W80 Multi-Cell System/ W90 Multi-Cell System to provide such flexibility. The headset can register to the DECT base directly as a stand-alone device or share a SIP account with a DECT handset to dial out or manage the call. With DECT technology, the headset can provide a stable connection and an excellent operating range of up to 300 meters. So you can move freely on the floor without worrying about headset range. Besides the basic calling features like the answer, reject, hold, and mute, the headset also has a Push-to-Talk feature. You can send instant Push-to-Talk messages or set up a full-duplex Push-to-Talk meeting via the headset to ensure the whole team is tightly connected. With the programmable key on the headset, you can choose a redial or speed dial feature according to your needs. The intercom feature also allows you to make internal calls without a network, and the intercom call is free. Also, the headsets can provide you with all-day wear comfort.

Push-to-Talk
Hold the Mute button and speak, all the members in one group can hear you, and the communication is full-duplex. When you finish, release the button. You can also press the Call Control and Mute buttons simultaneously, the Push-to-Talk meeting will be held for 3 minutes. So you can talk to members without holding down the Mute button.

Available in Two Different Modes
WHM621 with Charging Cable can be used in two different modes:

In Paired Mode, it is synchronized with an existing Yealink DECT handset. For example, a common phone number can be used, and the call can be made via the handset. Then, you can push the call to the headset.

In Stand-Alone Mode, WHM621 with Charging Cable functions as a stand-alone phone, which means it has a SIP account like a common phone.

Be Heard Crystal Clearly
With Yealink Acoustic Shield Technology, the two microphones built in WHM621 with Charging Cable block the background noise automatically but ensure the participant’s voice is heard clearly, greatly boosting the communication efficiency.
