COIN BATTERIES

NO OBVIOUS SYMPTOMS

Unfortunately, it is not obvious when a button or coin battery is stuck in a child's esophagus. There are no specific symptoms associated with this.

The child might:

• Cough, gag or drool a lot

• Appear to have an upset stomach or a virus

• Be sick

• Point to their throat or stomach

• Have pain in their abdomen, chest, or throat

• Be tired or lethargic

• Be quieter or more clingy than usual or otherwise “not themselves”

• Lose their appetite or have a reduced appetite, not want to eat solid food, or be unable to eat solid food

These sorts of symptoms vary or fluctuate, with the pain increasing and then subsiding. A specific symptom to button and coin battery ingestion is vomiting fresh (bright red) blood. If the child does this seek immediate medical help. The lack of clear symptoms is why it is important to be vigilant with “flat” or spare button or coin batteries in the home and the products that contain them.

The SRAM DH Transmission derailleur is only compatible with a SRAM DH 7 Speed T-Type cassette. The system is compatible with most SRAM T-Type cranksets, chainrings, and chains with the exclusion of the chain, CN-TTYP-XXSL-A1. Consult the AXS Component Compatibility Map for compatibility information.

Download the SRAM AXS app, available for free in the app stores, to create your SRAM account, add your components, and customize your SRAM AXS experience.

Through the app, you will also be able to:

• Connect your components via Bluetooth to the SRAM AXS app.

• Build and personalize multiple bicycle profiles.

• Monitor bicycle performance and readiness.

• Customize component behavior to match your riding style.

• Assign custom actions to your controls.

For component customization within the SRAM AXS app, all AXS components must be paired into a single system. Procedures for pairing multiple systems, such as an AXS seatpost and AXS drivetrain, can be found in the System Pairing section.

For optimal system performance and compatibility make sure you have installed the latest version of the SRAM AXS app and component firmware. Firmware updates are performed through the app.

Highly specialized tools and supplies are required for the replacement and maintenance of your SRAM components. We recommend that you have a qualified SRAM dealer work on your SRAM components.

It is recommended that you periodically clean your electronic components.

Use a damp cloth to wipe off any dirt and debris. Clean the components with soap and water only. Rinse thoroughly with water and allow the components to dry.

Always maintaining a clean and lubricated drivetrain will help extend your system performance and product component service life significantly.

It is recommended that you clean your chain, cassette, and chainring after frequent use, and immediately after riding in muddy, dusty, or other adverse conditions.

Use only biodegradable non-acidic cleaners to clean the cassette, chainring, and chain. Rinse thoroughly with water and wipe dry with a rag or blow dry with pressurized air.

Lubricate the chain with a dedicated chain lubricant. Wipe off excess lube.

The chain, cassette, and chainring wear together over time as a result of normal use. Parts will last longer with regular cleaning.

To determine if the parts need to be replaced, consult the Transmission Service Matrix. Depending on use case, it may be best to change the parts together to restore optimal drivetrain performance.

After installation and setup, you may remove and reinstall the rear wheel as needed. To remove and install the wheel put the derailleur in Open Mode. Before tightening the rear axle bolt, you must release the Cage Mode button and set the derailleur to Ride Mode.

Storage conditions: Temperature from -40°C  to 70°C ( -40°F to 158°F), humidity from 10% to 85%

Operating conditions: Temperature from -10°C to 40°C (14°F to 104°F), humidity from 0% to 100%

Component Service life: 5 years

Remove the SRAM batteries to preserve battery life during long term storage and when the bicycle is transported. Store the battery at least at 50% charge.

It is recommended that you periodically clean your electronic controllers.
