Student FAQ


What frequency should I use?

Most courses on campus use AA. The instructor will inform you if they are using a different frequency.

How do I change my frequency?

First, you must be in the presence of an i>clicker base station (with the i>clicker toolbar open) to be able to switch to that base’s frequency. Second, press and hold the power button on the i>clicker remote for 5 seconds, then press the letters of the frequency you want to switch to, i.e. “BB”. You should get a check mark (or green light) on your remote indicating that the frequency change was successful.

Note: i>clicker 2 remotes retain their frequency when turned off, whereas, the original and i>clicker + revert to “AA” when turned off.

I registered my i>clicker, but my scores aren’t showing up?

Make sure you register your i>clicker according to the instruction given to you by your instructor. Typically, on this campus, students register their i>clickers in their course website in Illinois Compass 2g (Blackboard) and/or Learn@Illinois (Moodle). Make sure that you are getting a positive confirmation from your i>clicker remote that your vote was counted (a checkmark or green light). If not, replace your batteries, move closer to the i>clicker base station, make sure you’re on the correct frequency (typically AA), or check with a neighbor. If you have done all those things, contact your instructor. Instructors are the ones responsible for synchronizing registrations and upload scores.

My i>clicker remote number is no longer legible, what can I do?

Please note: Your votes will be saved even if you have not yet registered, and you will receive credit for all past responses once you are able to register successfully; begin using your remote in class immediately.

  • In newer i>clicker remotes, you can find a second remote ID sticker inside the battery compartment behind the batteries.
  • If you are using i>clicker 2, the LCD will immediately display your 8-digit remote when you turn it on.
  • If you are unable to find your i>clicker remote number, you can take your remote to one of the campus bookstores (Illini Union Bookstore or TIS Bookstore). They have the equipment to be able to tell you your i>clicker remote number.

Can I register more than one i>clicker?

If you no longer have the original i>clicker that you started using in the class, you simply register the new one and you’ll retain the points you had under the old one and start getting the points for the new one. There is no need to unregister the old i>clicker.

Note: Make sure that you don’t use both i>clickers registered to you in the same class that causes and error and you’ll be contacted by the instructor.

Can I use my i>clicker in multiple classes?

The short answer is yes, you can use your i>clicker in multiple classes. There's no need to buy one for each class.

However, there are a couple scenarios in which you'd need to buy a new i>clicker remote for one of your classes:

  • If you have an original i>clicker or i>clicker + but your instructor requires i>clicker

All of our remotes will work alongside each other, but if your instructor will be asking numeric or alphanumeric questions, or using self-paced polling, you'll need an i>clicker 2 to fully participate. The original i>clicker and i>clicker + have exactly the same functionality and there would never be a reason to purchase an i>clicker + if you already have the original remote.

  • If you purchased REEF Polling, but your instructor requires a physical i>clicker remote.
Your instructor will usually specify on his/her syllabus which i>clicker remote is required. Check there before sending him/her an email. If you know you'll need to use i>clicker in multiple classes, the i>clicker 2 is the safest bet, since it will work no matter which question types your instructor requires.

Can I share my i>clicker remote with my roommate?

Yes, as long as you are not taking the same class at the same time. Both of you can simply register the remote with your respective names and student IDs. 

Please note: If your course requires you to register on i>clicker.com, the second person who registers a used/borrowed remote will be charged the remote registration fee of $6.99.  The person who registered it first does not have to pay that fee. Further, courses requiring you to register in Illinois Compass 2g or Learn@Illinois, will also not have to pay the extra fee.

How long do the batteries last?

New batteries supply approximately 200 hours of use. Original i>clicker uses 3 AAA batteries. New i>clicker + or i>clicker 2 remotes use 2 AAA batteries. Low battery indicator lights on the i>clicker and i>clicker + remotes will indicate that you need to replace the battery; i>clicker2 remotes have a battery life icon on the LCD display.

I changed the batteries—why isn't the remote working?

When the problem occurs after battery replacement it can almost always be traced to one of two things: 

  • The batteries used for replacement are Duracell or sometimes a generic brand. Duracell (and some generic brand) batteries cause a problem in the device.

This appears to be due to differences between the dimensions on the inside of the remote and the positive terminal on the Duracell batteries that keep the two from making contact.

  • Only two of the three batteries in the remote were actually replaced.

The second cause only two of three batteries being replaced is actually the most common problem we see with returned remotes. The batteries make a very tight fit in the remote and so the third battery frequently gets stuck at the top. The remote has to be tapped a bit in order to shake the last battery loose. For this reason many customers only see two batteries come out of the remote and so they only put two back in. The third battery is still dead or very weak and so customers still experience power problems not knowing that only two batteries were replaced. Please remove all three batteries from the unit and replace them with three new batteries (don't reuse the batteries that just came out of the device). While the batteries are out of the remote it is also a good idea to tighten the two visible screws on the back of the remote before replacing the batteries. We know that Energizer batteries work and so we suggest using those if you have them.


My clicker is lost or stolen. Can you help me track it down?

We're not able to help you "track down" your clicker if it's been lost or stolen. There are two reasons:

  • We don't know who you are or who the rightful owner of a clicker is.
  • To protect your privacy we don't share the information from our registration database (e.g., name, student ID). 

Why do I see the "No base" message or red light?

There are a couple of reasons for receiving the “No base” message on your i>clicker 2 remote or a red light on the original i>clicker or i>clicker + remotes.

Here are a couple possible solutions:

  • Make sure that you are set to the same frequency that your instructor is using. This is the most common cause of the "No base" message. The instructions are on the back of your remote. Note: You can only change your frequency once a session has begun.
  • Please make sure that the polling session has already started. You will not be able to vote until the polling session has started.

If none of these steps correct your issue, your i>clicker remote may be damaged. The i>clicker remote has a one-year warranty; please contact i>clicker for more information.


Where do I register my i>clicker?

Follow the instructions given to you from your instructor. Typically, on this campus, students register their i>clickers in their course website in Illinois Compass 2g (Blackboard) and/or Learn@Illinois (Moodle).

Do I have to pay a fee?

If you buy a used remote that you register on iclicker.com, you will have to pay a one-time fee of $6.99 USD.

A used i>clicker remote is identified when neither the student name nor the student ID have been previously registered with the remote ID. This means that if your instructors require that you register with different student IDs (e.g., one requires an email address while another requires a student number), you’ll be able to register multiple times and only pay the fee once.

Currently, only students who register on iclicker.com will pay a fee. In subsequent terms, students who register within an LMS (Blackboard, Canvas, Moodle, Sakai, D2L) will also have to pay the registration fee.

Student who purchase a new remote are able to register at no charge.

How do I unregister?

There is no need to unregister your remote, even if you will no longer be using it. If you sell the remote, the buyer will simply need to register the remote under his/her name.

Please note: At that time, the buyer will need to pay a $6.99 registration fee to register the remote on iclicker.com.

What is the difference between i>clicker, i>clicker +, and i>clicker 2 remotes?

The original i>clicker and i>clicker + remotes both have A-E buttons and can be used for multiple choice polling. i>clicker 2 has A-E buttons for multiple choice, and additional buttons to accommodate numeric and alphanumeric responses, as well as an LCD screen. If your instructor plans to ask numeric or alphanumeric questions, you will need an i>clicker 2 remote in order to be able to participate. Check with your instructor to see which i>clicker remote you'll need for your course.


Does every course use REEF Polling?

No, it’s up to the individual instructor to decide whether or not to enable REEF Polling for that particular course. If the instructor enables REEF Polling, you can now use either your i>clicker remote or REEF Polling app to vote in class. This is a convenient option in case you forget to bring your i>clicker remote or smart device to class.

Note: You can only use one device to answer a question in a polling session. Meaning, you cannot answer one polling question with both devices and receive double credit.

What should I use as Student ID in REEF Polling?

If you are using the REEF Polling mobile solution in class, please make sure you enter your Net ID (first part of your email before the @illinois.edu) in the Student ID field in your REEF profile. To do this, log into your REEF account and edit your profile. This is necessary in order to receive points for your i>clicker participation in class.

How do I register REEF Polling by i>clicker?

  • Log in to your account and press the Menu button. Then, choose Profile.
  • Click Edit Account.
  • Enter the student ID that matches your instructor's roster (this is your Net ID, the first part of your email, before the @illlinois.edu) and press Save.    

The next time your instructor syncs his/her roster, your responses will be matched with your name.

Why isn't my instructor listed in REEF Polling by i>clicker?

Your instructor decides if you'll be able to use REEF Polling in the class and enables it in her settings. Check to make sure it's allowed in your course before purchasing a subscription.

Can I use REEF Polling by i>clicker instead of purchasing a remote? 

Possibly. Your instructor has to allow REEF Polling to be used in the course and enable it in their software. Usually instructors will indicate on the syllabus if you'll be allowed to use REEF Polling.

You'll have a free 14-day trial when you first sign up—use that time to make sure REEF Polling is the right choice for your class.
