Sennheiser OfficeRunner Dipswitches and What They Do

Dipswitch Settings (going left to right)

1. Move down when there is an EHS (except Shoretel or mobile EHS)
2. Moved down when there is a Mobile EHS plugged in
3. If there are many wireless units being used in a small space and the user is experiencing interference from other wireless units move this down
4. Move down for “Auto On” feature. Headset will turn on when headset leaves the base
5. This switch controls Wideband / Narrowband mode. When in wideband mode (UP) the call clarity and range should be better but battery talk time is 8 hours. Narrowband mode (DOWN) can reduce range but provide 12 hours of talk time
6. This switch regulates volume to comply with European standards when in the DOWN position. So, just leave it UP

There is a “cheat sheet” on the inside of the back panel for the charging base.

Please Note: If dipswitch 1 or 2 is down, the Sennheiser lifter will not work and the receiver will not work for calls when plugged into the base. So have those switches up if using a lifter.

Other Settings on the Sennheiser Headset Base

Compatibility Settings (white button that says A-B-C):

A is the most common.

C is generally used in headset jacks on Cisco phones.

Microphone Volume (white wheel that looks like a clock):

We want to leave this set between 5 and 7 most of the time. Any higher than 7 and you may experience an echo.
