High drip resistance against sweat, rain, and sprays Features The inside of the unit’s casing includes packing, and the unit’s connectors are drip resistant. These features provide the unit with a drip resistance equivalent to IPX4/IPX5 (according to Sony test conditions). The DWT-B03R is a drip-resistant digital wireless transmitter featuring a highly durable yet compact and lightweight design.
e + and – buttons Selects the functions or values shown on the display. Holding down the – button while turning the unit on activates the pairing operation for the wireless remote control function. Holding down both the + button and – button at the same time starts the receiver search function. Parts Identification f Battery charger connector Connects to the BC-DWX1 battery charger (not supplied), and allows you to charge the lithium-ion battery inserted in the unit.

off, and never touch the terminals directly with your hands. • Always use genuine Sony lithium-ion batteries. bag, for example, and keep it away from metal objects during transport or storage. • The battery will slowly discharge, even when the unit is turned off. Remove the battery from the unit before extended periods of disuse. Remaining battery indicator Indicates the remaining battery charge. Replace the battery with a charged battery when the remaining battery indicator starts to blink.
Setting the Transmission Channel The unit provides groups of interference-free channels. When using multiple wireless microphones and transmitters at the same time (simultaneous multi-channel operations) within the same area, you must use channels within the same group to prevent signal interference.
RF REMOTE function is enabled and remote control is possible. Using Cross Remote Using Cross Remote with a previous pairing setting The unit is equipped with a wireless remote control function that allows the unit’s settings (low-cut filter, attenuation controls, power controls, etc.) to be controlled from the receiver or other devices. This makes it easier to operate and manage the microphone system while in the field. The IEEE802.15.4-compliant wireless remote control function uses the 2.
Finding the unit from a paired receiver Using the Encrypted Transmission Function Some receivers are equipped with a function that finds the transmitters with which they are paired. When this search function is used on a receiver that is paired with the unit, the unit’s organic EL display will blink. The unit is capable of transmitting encrypted signals to prevent unwanted surveillance. To use the function, select one of the following encryption modes.
On the receiver side, select REMOTE (wireless remote) as the encryption key exchange method, and perform encryption key exchange. REMOTE cannot be selected when the wireless remote control function is disabled. Basic Menu Operations Setting item Notes If the receiver does not support AES256 mode, select SECURE KEY. For details, refer to the receiver’s operating instructions. The unit searches for the receiver with which it is paired.
• FACTORY PRESET (factory settings) function • VERSION (software version) display Menu Settings This section describes the various setting items and their values. Underlined values represent factory settings. Unit Name Setting (NAME) Specify up to 16 characters for the unit’s name. The factory setting is the unit’s model name and serial number. The unit’s name is sent to the receiver as metadata and used by the receiver to distinguish between different transmitters. + button: Displays the character set.
The audio attenuator setting can be changed from the receiver and other devices via the wireless remote control function. • After selecting the frequency band, select the group and channel. To start signal transmission with the selected frequency band, group, and channel, turn off the unit and then turn it on again. For details, see “Using Cross Remote” (page 8).

You can also configure the maximum transmission power. The MIC/LINE setting for the audio input level can be changed from the receiver and other devices via the wireless remote control function. For details, see “Maximum Transmission Power Setting (MAX RF POWER)” (page 14). For details, see “Using Cross Remote” (page 8).

Attaching the Belt Clip Attaching the supplied belt clip allows you to attach the unit to the speaker. Software Version Display (VERSION) Display the version of the unit’s software. Insert the belt clip into a hole on one side of the unit, and then insert it into the hole on the other side.

Troubleshooting If you encounter a problem when using the unit, check the following. If the problem persists, contact your Sony representative. Symptom Cause Solution Interruptions occur in the receiver audio. The unit is too far from the receiver. Reduce the distance from the receiver, and check the reception. The transmission power setting is set to “L: 2 mW.” Increase the transmission power (page 14). The channel setting on the unit is different from that on the receiver.
Symptom Cause Solution The battery discharges quickly. The battery is not sufficiently charged. The battery will slowly discharge naturally, even when the unit is not used. Fully charge the battery. If the remaining charge is not properly displayed after fully charging the battery, the battery may have reached the end of its life cycle. Use a new battery pack. The ambient temperature is extremely high or extremely low. This is not a malfunction.
• Wipe the surface of the unit and its connectors using a soft, dry cloth. Never use chemicals, such as thinner, benzene, or alcohol, as they may damage the finish. Important Notes on Operation Notes on Simultaneous MultiChannel Operation The life expectancy of the electrolytic capacitor is about 5 years under normal operating temperatures and normal usage (8 hours per day; 25 days per month). If usage exceeds the above normal usage frequency, the life expectancy may be reduced correspondingly.
becomes drastically reduced, it may have reached the end of its life cycle. Purchase a new battery in such cases. • The battery’s life cycle will vary depending on storage methods, usage conditions, and environments. For details on how to check the software version, refer to the device’s operating instructions.
