About This Remote

A 5.1-channel home cinema system, the Onkyo HTS3705 pairs a dynamic high-current receiver with a full-range speaker set and passive subwoofer – and this Onkyo HTS3705 remote gives you direct control over the whole package. It carries part number RC-879M, and it sends standard infrared commands to the system without any programming or pairing step required. The HTS3705 manages six HDMI inputs alongside a single HDMI output with ARC, passes 4K/60 Hz video, and decodes Dolby TrueHD and DTS-HD Master Audio through a 192 kHz/24-bit TI Burr-Brown DAC – all functions this replacement is designed to match the original button layout for.

Why buy this remote

  • Covers a system built around six HDMI inputs and a single ARC-capable HDMI output.
  • No programming step required – point it at the receiver and it responds.
  • Matches a system with Dolby TrueHD and DTS-HD Master Audio decoding on board.

Frequently asked questions

Does this remote control both the receiver and the included speakers together?

The HTS3705 is a packaged system – the receiver drives the bundled full-range speakers and passive subwoofer. This remote controls the receiver unit, which manages the entire system including volume and source selection for the speaker package.

Will this remote work with the HTS3705's ARC-enabled HDMI output?

Yes. The RC-879M remote controls the HTS3705 receiver, which includes one HDMI output with Audio Return Channel (ARC). Functions associated with that output are accessible through the receiver's standard command set, which this replacement carries.

My old remote shows a different number on its label. Is this still the right part?

Yes. This remote is also sold under the label 24140879. Both labels are the same physical part, supplied here as the RC-879M.

Does the HTS3705 support 4K video sources?

Yes. The HTS3705 passes 4K/60 Hz video through its HDMI section. This remote controls the receiver that handles that signal routing.

How many HDMI inputs does the HTS3705 have?

Six. The HTS3705 includes six HDMI inputs, all managed through the receiver this remote controls.

What audio formats does the HTS3705 decode?

The HTS3705 decodes Dolby TrueHD and DTS-HD Master Audio, and processes audio through a 192 kHz/24-bit TI Burr-Brown DAC. This replacement remote is catalogued as part number RC-879M and gives full access to the receiver's audio controls.

What batteries does the RC-879M remote use?

It takes two AAA batteries.

Shipping and Delivery

📦 Shipping Information

At USA Remotes, we’re committed to getting your replacement remote to you fast, free, and hassle-free — the same way your remote shows up ready to use, with no pairing or programming. Below you’ll find everything you need to know about how we ship, how long it takes, and what to do if anything goes sideways.


🚚 How much does shipping cost?

Shipping is free on every order — always. No minimum purchase, no handling fees, and no surprise charges at checkout. The price you see is the price you pay.


🏢 Where do you ship from?

Every order ships from our U.S. fulfillment center. We’re a U.S.-based company, so your remote never sits in customs or crawls in from overseas — it ships domestically and arrives quickly.


⏱️ When will my order ship?

We move fast. Orders placed before 2:00 PM Mountain Time (MT) on a business day ship the same day. Orders placed after the cutoff, on weekends, or on public holidays ship the next business day.

Business days are Monday through Friday, excluding national holidays.


🚀 How long will it take to arrive?

Once your order leaves our warehouse, most deliveries arrive within 2–4 business days. Paired with same-day processing, the majority of customers have their remote in hand within just a few days of ordering.

Delivery windows are estimates, not guarantees, and can run a little longer during weekends, holidays, peak seasons, or severe weather.


⚡ Do you offer faster (expedited) shipping?

We don’t currently sell a separate paid expedited option, but many orders go out via USPS Priority Mail, which typically reaches most U.S. addresses in 2–3 business days at no extra cost.

If you’re in a time-sensitive situation, email us at cs@usaremotes.com before you order and we’ll let you know what’s possible.


📬 Which carriers do you use?

Because remotes are small and light, the vast majority of orders ship via USPS (United States Postal Service) — usually USPS Ground Advantage or Priority Mail. For larger multi-remote orders we may use UPS or FedEx. The carrier is selected automatically to get your order to you as quickly and safely as possible.


🌎 Do you ship internationally?

Yes — we ship internationally. International orders typically arrive within 8–14 business days, depending on your destination and how long it spends in local customs. Carriers and shipping methods vary from country to country, so your order travels the most efficient route available.

Please note: international shipments may be subject to customs duties, taxes, or import fees charged by the destination country. These are set by your local customs authority and are the responsibility of the recipient.


🏝️ Do you ship to Alaska, Hawaii, U.S. territories, and military addresses?

Yes. We ship to all 50 states, U.S. territories (including Puerto Rico, Guam, and the U.S. Virgin Islands), and APO/FPO/DPO military addresses. Because these rely on USPS, transit times may run a bit longer than the standard 2–4 business days.


📮 Do you deliver to PO Boxes?

Absolutely. Since most orders ship via USPS, PO Box delivery is no problem. On the rare occasion an order ships via UPS or FedEx, we may reach out for a physical street address.


🔍 How do I track my order?

As soon as your order ships, we’ll email you a tracking number. You can also check your status anytime on our Track Your Order page. If you don’t see the email within a day of ordering, check your spam folder or get in touch.


📧 Why does my order say “Completed”?

When your order ships, you’ll get a confirmation email and your order status will change to “Completed.” That wording can be a little misleading — “Completed” simply means your order has shipped and left our warehouse, not that it’s already been delivered. Just use the tracking number in your email to follow it the rest of the way to your door.


📭 My tracking number isn’t updating — what should I do?

It’s normal for tracking to go quiet for a day or two, especially right after a label is created or over a weekend — carriers don’t scan a package at every stop. If there’s no movement for more than 3–4 business days, email us at cs@usaremotes.com and we’ll chase it down for you.


📦 My tracking says “Delivered” but I don’t have it

If the carrier marked your package delivered but it’s not in your hands:

  1. Check around your home — porch, mailbox, side door, garage, or wherever packages usually land.
  2. Ask household members or neighbors in case someone brought it in for you.
  3. Wait 24 hours — packages are sometimes scanned as delivered slightly before they actually arrive.

If it still hasn’t turned up:

  • Contact your local USPS office — they can pull GPS delivery confirmation showing exactly where the package was scanned.
  • Contact us at cs@usaremotes.com or (720) 204-8889. We’ll help open an investigation and retrieve the GPS scan data if needed.

Insurance: Our shipments include carrier insurance against loss or damage. We’ll guide you through the claim process with the carrier and stay on it until it’s resolved.


💔 My remote arrived damaged or doesn’t work

Every remote is tested and packed with care, but if yours shows up damaged or has a defect, you’re covered by our 1-year warranty and full compatibility guarantee. Just contact us at cs@usaremotes.com with your order number (and a quick photo if it’s physically damaged), and we’ll arrange a replacement or refund right away. Full details are in our Returns & Refunds policy.


🏠 What if I entered the wrong address?

If you spot a mistake in your shipping address, contact us immediately. If your order hasn’t shipped yet, we can fix it. If a package comes back to us as undeliverable (wrong or incomplete address), we’ll reach out to arrange a re-ship to the correct address.


🔀 Why did my order arrive in separate packages?

If you ordered more than one remote, your items may occasionally ship in separate packages or arrive on different days. Each shipment gets its own tracking number, so don’t worry if one lands before the other.


❄️ Holiday & weather delays

Carrier networks slow down during major holidays and severe weather. We still ship on our normal same-day schedule, but transit times may stretch during these periods — and once a package is with the carrier, those delays are outside our control.


✅ Our commitment to you

Your satisfaction is our priority. If anything goes wrong with your shipment, we’ll work directly with USPS or the relevant carrier to make it right and get your remote to you safely. Nobody should be stuck without a way to control their TV, sound bar, or AC.
