1. Battery Installation
The RC-1173 remote control requires two (2) AAA batteries for operation. Follow these steps to install the batteries:
- Locate the battery compartment cover on the back of the remote control.
- Slide the cover downwards or press the latch (if present) to open the compartment.
- Insert two AAA batteries, ensuring that the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.
- Slide the battery compartment cover back into place until it clicks securely.

2. Initial Use
Once batteries are installed, the remote control is ready for use. No programming is typically required for this replacement remote. It operates using infrared (IR) technology.
Operating Instructions
To operate your Denon amplifier with the RC-1173 remote control, ensure a clear line of sight between the remote and the amplifier's remote control sensor. Obstacles can block the infrared signal.

Maintenance
Battery Replacement
Replace batteries when the remote control's response becomes sluggish or stops functioning. Always replace both batteries at the same time with new AAA alkaline batteries. Do not mix old and new batteries, or different types of batteries.
Cleaning
To clean the remote control, use a soft, dry cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the remote's surface or internal components.
Storage
Store the remote control in a cool, dry place away from direct sunlight and extreme temperatures. If the remote will not be used for an extended period, it is recommended to remove the batteries to prevent leakage.
Troubleshooting
- Remote not responding:
- Check if the batteries are correctly installed and not depleted. Replace if necessary.
- Ensure there are no obstacles between the remote control and the amplifier's sensor.
- Verify that the remote control is pointed directly at the amplifier's sensor.
- Confirm that the 'REMOTE MODE' is set to 'AMP' if your amplifier requires this selection.
- Specific functions not working:
- Ensure the amplifier is powered on and functioning correctly.
- Some functions may be specific to certain amplifier models or connected devices. Refer to your amplifier's original manual for detailed function compatibility.
If your amplifier model is not PMA-720AE or PMA-520AE, or if you continue to experience issues after following these troubleshooting steps, please contact the seller for assistance.
