3.1 Charging the Speaker

3.2 Powering On/Off
Locate the 'ON/ECO/OFF' switch behind the waterproof door on the side of the speaker. Slide the switch to 'ON' to power on the speaker. To conserve battery, slide the switch to 'ECO' mode, which slightly reduces volume levels for extended playback. Slide to 'OFF' to power down.
3.3 Bluetooth Pairing
- Ensure the speaker is powered on.
- Press and hold the Bluetooth pairing button (often combined with Play/Pause) on the top panel until the Bluetooth indicator light flashes, indicating it's in pairing mode.
- On your mobile device, enable Bluetooth and search for available devices.
- Select "iHome iBT35" from the list.
- Once paired, the Bluetooth indicator light will become solid, and you will hear an audible confirmation.
3.4 Using Aux-in
For devices without Bluetooth, connect an audio cable (not included) from your device's headphone jack to the 'AUX-IN' port on the speaker (located behind the waterproof door). The speaker will automatically switch to Aux-in mode.

5. Maintenance
5.1 Maintaining Waterproofing
To ensure the iBT35 remains waterproof, always make sure the side protective door covering the ports (AUX-IN, POWER IN, ON/ECO/OFF switch) is completely closed and securely sealed before exposing the speaker to water or moisture.
5.2 Cleaning
Clean the speaker with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the finish or rubberized coating.
5.3 Resetting the Speaker
If the speaker becomes unresponsive or experiences connectivity issues, locate the small 'RESET' pinhole button behind the side waterproof door. Use a thin object (like a paperclip) to gently press and hold the reset button for a few seconds. This will restart the speaker without losing pairing information.
6. Troubleshooting
- No Power: Ensure the speaker is charged. Connect it to a power source using the Micro USB cable. Check the 'ON/ECO/OFF' switch is in the 'ON' or 'ECO' position.
- Cannot Pair via Bluetooth: Make sure the speaker is in pairing mode (flashing Bluetooth indicator). Ensure your device's Bluetooth is enabled and within range. Try turning both devices off and on again. If issues persist, perform a reset on the speaker.
- Poor Sound Quality/Distortion: Reduce the volume on both the speaker and your connected device. Ensure there are no obstructions between the speaker and the Bluetooth device. If using Aux-in, check the cable connection.
- Speaker Not Waterproof: Verify that the side protective door is fully closed and sealed. Any gap will compromise its waterproof capabilities.
