Setting the AA Battery Type
To ensure accurate display of transmitter runtime, set the battery type in the transmitter menu to match the installed AA battery
type (the default setting is Alkaline). If a Shure rechargeable battery is installed, selecting a battery type is not necessary and
the battery type menu will not be displayed.
Press the menu button to navigate to the Battery screen.
Press enter, then use the menu button to select the installed battery type:
Alkaline = Alkaline
NiMH (nickel metal hydride)
Lithium (non-rechargeable, 1.5V max)
Press enter to save.
Shure SB903 Rechargeable Battery
The SB903 lithium-ion rechargeable battery powers the SLX-D transmitters. Use the SBC10-903 single bay or SBC203 dual
bay chargers to recharge SB903 batteries.
Important: Always fully charge a new battery before first use.
To fully charge a new SB903 battery, it must be placed directly in the charger. After the first charge, the battery can be charged
by docking the transmitter in the SBC203 dual-bay charging station.
Single Bay Charger
The SBC10-903 single bay charger offers a compact charging solution.
Plug the charger into an AC power source or USB port.
Insert a battery into the charging bay.
Monitor the charging status LEDs until charging is complete.

contact Shure Technical Support.
Important Tips for Care and Storage of Shure Rechargeable Batteries
Proper care and storage of Shure batteries results in reliable performance and ensures a long lifetime.
Always store batteries and transmitters at room temperature
Ideally, batteries should be charged to approximately 40% of capacity for long-term storage
During storage, check batteries every 6 months and recharge to 40% of capacity as needed
Average Charging Times

Sound Check and Gain Adjustment
Navigate to the receiver's Gain screen to test the transmitter at performance levels. Adjust the gain to keep the audio indicator
within the optimal range. Reduce the gain if there is audible distortion of the audio.

System Set Up
Creating Audio Channels
Awirelessaudiochannelisformedwhenareceiverandtransmitteraretunedtothesamefrequency.TheSLXDsystempro
vides 3 methods for tuning the receiver and transmitter to the same frequency:
Guided Frequency Setup: A step-by-step guide to walk you through the process
Scan and IR Sync: The receiver scans the RF spectrum for the best available frequency and an IR sync automatically
tunes the transmitter to the receiver frequency
Manual Group, Channel, or Frequency Assignment: Manually set the receiver and transmitter to the same group and
channel number, or frequency
What are Groups and Channels?
To minimize interference, Shure wireless systems organize RF bands into predefined groups and channels. A group is a set
ofcompatiblefrequencieswithinafrequencyband.Asinglefrequencywithinagroupisachannel.Tuneareceiverandtrans
mitter to the best available channel within its group to set up your system.
Note: Becausegroupsarebanddependent,somesystemsdon'thavemultiplegroups.SinglegroupbandshavethesameRFperformanceasthosewithmul
tiple groups.
All receivers in the same band should be set to the same group. You can set them manually, or use the Guided Frequency Set
up to walk you through the process.
Connect all the receivers in your system using Ethernet cables. For best results, use a network switch when connecting 3 or
more receiver units.
Important! To avoid interference, before you begin:
Turn off all transmitters for the systems you are setting up. This prevents them from interfering with the frequency scan.
Turn on the following devices so they are operating as they would be during the presentation or performance. This will allow
the scan to detect and avoid any interference from these devices:
Configured wireless systems or devices
Computers
Large LED panels
Effects processors
CD players
Using the Guided Frequency Setup
Set up a new system:
Push the control knob on the receiver and select 1. Frequency Setup > 1.1 Guided Frequency Setup.
Select Initialize My System and push the control knob to continue.
Turn off all transmitters you plan to use with your system.
Select start scan.
After the scan is done, push the control knob to assign frequencies to the receiver.
Turn on the transmitter you plan to use with this receiver.
