The Wispr is optimized to operate with Welch Allyn® Wall Mount Units and Welch Allyn Lithium Ion Rechargeable Battery Handles. These are the recommended power sources for powering your Wispr Digital Otoscope. In addition, the Wispr can be utilized with the Heine otoscope power handle. (Not included with Wispr Digital Otoscope purchase.)
Wispr Compatible Power Handles
(Required, but not included with the Wispr)
Welch Allyn 71900
Welch Allyn 71000-A
Direct Plug-in Rechargeable Handle
(Please note: WiscMed supports the use of the Welch Allyn 71000-A handle with a minor modification. We have found that an additional battery spring is necessary to prevent a bump on the handle from resetting the Wispr. (Image 2 above) Please contact WiscMed and we will send you the required spring at no charge. Installing the spring requires no tools and takes less than 30 seconds. Instructions to install the spring can be found here)

The “AV” version stands for “Automatenverschlusses” (Automatic Connector). The “AV” version handle requires a Heine AV to TL adapter (Heine X-002.98.006) to work with the Wispr.
