Can I become a Kar-Tech distributor?

Were always looking for new channels to bring Kar-Tech products and solutions into the market. If you service an area that isnt covered well by existing distributors, or you serve a market other than mobile hydraulics, please contact our sales team to discuss.We do have some minimum requirements that well want to investigate, after which youll find that were very proactive at working with and building up new channel partners.

What is the typical range on Kar-Tech"s wireless products?

Conservatively we offer products with 300’, 1000’, and 2500’ ranges.

What type of battery life can I expect from my wireless transmitter?

First, you have to know what we are referring to here—most transmitters can stay ON for several months.
The important measure for determining battery life is Button Press time—that is to say how long the battery will last while transmitting. This will vary and is dependent on what battery is being used. For example it is typical to get 30+ hours of button pressing transmission from our hand held transmitters. Typical button press is 2 seconds which would result in getting approx. 50,000 button presses on a fully charged battery.
Kar-Tech can make different batteries available for hand held, pistol grip or belly pack style remotes.

How do I teach a transmitter to a receiver?

Starting with the power off on the receiver, press and hold the transmitter power button for 10 seconds until both LED’s flash together. This signifies that the transmitter is in teach mode. turn on the power at the receiver and teach is complete.
Though this process works for many of our common/stocked systems, some legacy and OEM-specific products have different teach patterns. Please contact our service team at (262) 646-9444 if the above technique doesn’t work for you.

Can I run more than one transmitter to one receiver?

In most cases, yes; Kar-Tech calls this cloning. As there may be safety concerns for the user or manufacturer of the equipment being controlled to consider, we don’t publically post these instructions.
If you’ve bought your remote directly from Kar-Tech, contact us for instructions, otherwise, please contact the manufacturer of the equipment we’re controlling.

Can I run more than one recever with one transmitter?

Often yes, but this can be very involved, and is best done at the application level, not after the fact. There are many factors to consider. Certain systems have this functionality built in, and available from stock. Contact our sales team for more information.

What do the green and red lights signify?

Green LED is wireless status – slow blink is power on at the transmitter, fast blink is power on and in two-way communication with the receiver.
The Red LED is used for diagnostics and battery – the number of blinks indicate which output is not hooked up or disconnected (see your manual or receiver decal for specific blink code messages), consistent blink is 20% or less battery life remaining on the transmitter.
The RED led will come on when charging – and the GREEN led will come on when complete.

What’s a “sleep” time?

Kar-Tech products ship by default with the following configuration: Transmitters will stay on as long as the receiver is on, then turn off automatically ten minutes after the receiver is turned off, in order to save power (15 minutes for MINI products). If you want something different, please let your salesperson know. Some products have multiple sleep options that may be programmable – most stocked remote systems on our website have this built in.
When designing a custom project, please keep in mind how sleep times may affect your latching outputs.

What forms of payment do you accept?

In addition to PayPal, we accept Visa, MasterCard and American Express at checkout.
And we rarely turn down homemade cookies.

When do you charge my credit card?

How does getting a custom-made product work?

Contact our sales team with your application requirements. From there, you’ll receive a highly detailed quotation. Review the pricing, and check that everything you expect is detailed – our quotations are our sole design input to engineering. We’ll quote both a prototype and production lead time. The prototypes (or first articles) will generally run 6 – 8 weeks after receipt of order.
Approximately two weeks or less after receiving your order, you’ll receive a full set of approval documents from us. These will detail layout, artwork, pinouts, etc. With your approval, we’ll release to production and software development. Please note that any time spent in the approval process (delays, re-laying out transmitters, etc) is not accounted for in our prototype lead times and may be added to delivery. It’s important that you and your customers get these drawings back to us as soon as possible.
Despite the quantity of your initial prototype order, we’ll ship one unit before the balance and ask you to test it to make sure the unit works the way you want. Some customers wish to waive this and ship all the initial units at once. We can accommodate that, but ask that you let your salesperson know early on. If changes come up with the first shipment that weren’t provided for in the initial spec, you may be asked to pay return shipping if necessary if we’ve shipped more than the prototype prior to approval.
Once the prototype is approved, we’ll release your balance, and the product will be locked for production.

What is your return policy?

We generally do not accept any returns on anything custom designed, or customized for OEM specifications – however, we do stand behind our warranty for any issues that may come up.
For standard, off-the-shelf product, we may accept returns if the articles are in like-new condition.
Please contact your salesperson for details.

Solving Range Issues

Wireless remotes are by nature sensitive to their installation and environment. Kar-Tech under-rates the range of our systems to account for much of this. However, from time to time, it"s necessary to spend some time optimizing your system to account for low range. We recommend you:
Install the wireless receiver as high on your machine as possible, and with the antenna in free air - with no metal behind it from any side.
Make sure you have a good ground connection straight back to the battery. Avoid using chassis ground if possible.
If you"re using a small engine on your machine, make sure you"re using resistor spark plug wires.
Try and remove any antenna extension cables if possible. If you"re using an antenna extension cable, make sure that the contacts are firmly made, clean, and not shorted.
If you still need help - shoot us some pictures of your installation, and we"re happy to help!

Where can I find my product"s Part Number?

Your product"s Part Number (P/N) is a 6-digit number that can be found just below the words Kar-Tech, Inc. on the small metallic sticker on your device (see image).

In this example, the part number is A10072A.
NOTE: There is a second sticker on many of our products that lists FCC information. This is unrelated to our Part Number information.

Where are Kar-Tech"s products serviced?

ALL of our products are serviced here in Delafield, Wisconsin—right where they are all manufactured

Where are the manuals and installation drawings?

After purchase, a pdf of the manual will be e-mailed to the e-mail address file during the order.

How long will it take to get my product repaired?

Generally speaking, about a week, if you respond promptly to our emails. This is highly dependent on the nature of the damage and the age of the product. Small issues on products made within the past five years will typically go much faster than major damage, or much older products which may take several weeks.

What does the service process look like?

We’ll ask you to start by requesting an RMA number from our service department, or by filling out THIS FORM. Send your product back to us with the RMA number clearly indicated on your packaging.
We’ll inspect the product, and send you an estimate via the email address you’ve provided. Once payment or a PO has been received, we’ll process the service work and send your unit back to you.
