Firmware update
Q:
Why should I update the firmware of my
receivers or transmitters?
A:
We recommend to always update all your receiv-
ers and transmitters to the latest firmware version
available in order to be able to benefit from addition-
al features or improvements on existing features.
Q:
How can I update the firmware of my
receivers or transmitters?
A:
You can update the firmware of the receivers
using either the "Sennheiser D1 SL Updater" PC soft-
ware or the "Wireless System Remote" (WSR) app.
The PC software is available free of charge from the
Sennheiser website (Link). The app is available free
of charge in the Apple App Store or the Google Play
Store.
A:
In order to update the firmware via the PC
software, you have to connect your receivers to
your computer network using network cable. The
"Sennheiser D1 SL Updater" PC software automati-
cally detects all receivers in the network, reads their
firmware version and offers to update the firmware
if a newer version is available.
A:
In order to update the firmware via the WSR app,
you have to connect your receivers to a WiFi router
using network cable. The mobile device with the app
must be able to access the WiFi network. The app
automatically detects all receivers in the network,
reads their firmware version and offers to update the
firmware if a newer version is available.
A:
Once the receiver firmware has been successfully
updated, the firmware of the associated transmitter
can be updated over the exisitng radio link with the
receiver. For this, the two devices must be paired.
If the paired transmitter runs a different firmware
version than the receiver, a dialog appears on the
receiver display panel prompting you to update the
firmware of the transmitter. Confirm the dialog to
start the update.
A:
We recommend updating the firmware before us-
ing the devices. Never update the firmware during a
performance.
A:
First, update the firmware of all receivers in one
step. Then, step by step, update the firmware of each
transmitter individually. Switch off all transmitters
apart from the one whose firmware you want to
update.
A:
A receiver can only be used with a transmitter that
runs the same firmware version. If the two devices
are running different firmware versions, the receiver
will prompt you to update the transmitter firmware
each time you try to pair the devices.
A:
Make sure to always update the firmware of
all your receivers. If a transmitter is paired with a
receiver that runs an older firmware version, the
newer firmware version of the transmitter can be
overwritten. An update is always transferred from
the receiver to the transmitter, but not vice versa.
Q:
Why is the firmware update from the
receiver to the transmitter interrupted?
A:
We recommend updating the firmware before us-
ing the devices. Never update the firmware during a
performance.
A:
First, update the firmware of all receivers in one
step. Then, step by step, update the firmware of each
transmitter individually. Switch off all transmitters
apart from the one whose firmware you want to
update.
A:
If the firmware update is interrupted, the device
restarts automatically. After the restart, the device is
ready for immediate use and maintains the previous
firmware version.
