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.

CAGE MODES

The Cage Mode button is used to position the derailleur cage to the various Cage Modes.

Open Mode: The derailleur cage is fully extended for rear wheel removal and installation.

Setup Mode: The derailleur cage is slightly extended to align the cage with either of the two key lines.

Ride Mode: The Cage Mode button is not depressed, and the derailleur cage is unlocked and not extended.

This section covers preparing the chain and derailleur for installation on bicycle frames not listed in the SRAM Full Mount Chain Length Guide or AXS App.

1. Measure the direct distance from the bottom bracket axis to the hub axis with the frame fully extended at 0% travel to determine the chainstay length (A) in millimeters.

2. Consult this chart to determine the length of chain links needed for your T-Type chain according to the chainring and chainstay length (A) combination on your bicycle.

Purple Chart Cells: Some bicycles may require more than one aftermarket chain to achieve the required length. Use a second compatible PowerLock to connect the chains and place the PowerLocks as far from each other as possible.

3. Count down from 126 to the number of chain links determined by the chart.

Use an approved chain breaker tool to break the chain at the inner link.

4. Record and use the following setup data for frames not listed in the SRAM database:

• Setup Key Position A.

• Setup Cog 21T, gear 7.

• SAG position for Tighten your Components section.

Proceed to the Setup Key Position section to continue system installation.

For Frames Not Listed in the SRAM Database and Idler Pulley Frame bikes, the bike must be in the Sag position during the Tighten the Components section.

Suspension sag is the percentage of full travel that the suspension compresses when the rider, including gear, is on the bicycle in a normal riding position.

Consult your frame manufacturer’s recommendations for appropriate sag percentage (typically 20-35%), and your suspension manufacturer's user manual for instructions on setting proper sag.

This section covers preparing the chain, setup cog, and setup position for Transmission installation on bicycle frames with an upper and lower idler pulley.

1. Wrap the chain around the large chainring, through the idler pulley, and the largest cassette cog.

2. Compress the bicycle until the rear shock is fully compressed. Deflate or remove the rear shock if necessary.

3. With the bicycle compressed, pull the two ends of the chain together and add one inner link and one outer link where the chain starts to overlap.

4. Use an approved chain breaker tool to break the chain at the inner link.

* Some bicycles may require a longer than normal aftermarket chain. In some cases adding an extra PowerLock into the system will provide the correct amount of links. Make sure to place the extra PowerLock as far from the connecting PowerLock as possible.

Some idler pulley bicycles may require a longer than normal aftermarket chain. In some cases adding an extra PowerLock into the system will provide the correct amount of links. Make sure to place the extra PowerLock as far from the connecting PowerLock as possible.

5. Record and use the following setup data for idler pulley frames:

• Setup Key Position A.

• Setup Cog 21T, gear 7.

• Sag position for Tighten your Components section.

Suspension sag is the percentage of full travel that the suspension compresses when the rider, including gear, is on the bicycle in a normal riding position.

Consult your frame manufacturer’s recommendations for appropriate sag percentage (typically 20-35%), and your suspension manufacturer's user manual for instructions on setting proper sag.

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.

Keep the extension cord installed in the transmission. It is not necessary to remove the extension cord when cleaning, storing, or transporting your bicycle.

Every 50 hours: Check the extension cord for damage such as cuts and breaks in the insulation.

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.
