Product Manual

Tips and Tricks:

Installation Tips

  • read the manual the comes with your car seat
  • read the vehicle manual
  • find a certified child passenger safety instructor or technician to help you and check your installations

 

Airline Use:

  • unfold the Diono car seat before boarding the plane and ask the flight attendant for seat belt extenders
  • make sure to install the car seat next to the window so passengers can get by in case of an emergency
  • make sure to take the slack out of the seat belt extender before connecting to the airplane seatbelt

Rear Facing Installation:

  • first secure the detachable base and slide in the locking mechanism
  • adjust the harness to be the proper height for rear facing
  • adjust the head support to fit your child properly

Folding and Unfolding:

  • to unfold: lay the car seat down on a stable flat surface and undo the velcro strap, tuck it in behind the fabric and open seat until clicked and locked.
  • to fold: remove the red velcro strap from behind the fabric and loosen up the harness as much as possible so they are at the top of the car seat. release the lever at the bottom of the car seat and push seat inward - secure the top with the red velcro strap.

 

Right For Newborn:

  • whether you buy an infant only car seat or an all-in-one convertible car seat, both car seats have to meet the same standard
  • seats like the Diono all-in-one convertible car seats come with an infant cushion insert to properly fit your child in the harness
  • all-in-one convertibles are more economical - they have a lot of room for growth for your growing child

FAQ's:

can the radian 3RXT fit 3-across in my car?

Most likely, yes, as long as you have 51” (129.6cm) in the back row from vehicle armrest to armrest. It may be necessary to install all three using the vehicle seat belt system.

can the harness straps be cleaned?

Yes, we recommend using a damp cloth with a solution of water and baking soda to wipe the straps clean. They cannot be saturated in any liquid, or they will need to be replaced. Replacement harness straps can be purchased on our website.

can I use the radian 3RXT from birth?

Yes, the weight limits on all our convertible car seats starts at 5lbs. The newborn must also meet a length requirement where the top of their shoulders reaches the lowest harness slot on the seat.

are the harness pads and buckle pads required on my seat?

Yes, they are required while your child is sitting in forward-facing. They are optional but recommended while sitting in rear-facing. The center buckle pad is required at all times.

Perfect Little Nugget Ice!
Color: Piano Black, Color: Piano Black
I'm not one to usually do reviews, but I really love this little countertop ice maker. I was spoiled when I had an icemaker in my fridge at our previous house. This Countertop Ice Maker Machine is AMAZING and I'm so thankful for it! The size and shape of the ice is just right. It's super! The little nuggets are just the right size. They are not too hard. The ice becomes light and chewy. It's like I was eating ice skittles, lol. So simple to use. Fast too! I believe I can get a full tray (about 5-6 scoops) in less than an hour, maybe 45 minutes? I guess it makes some noise, it's not loud enough to bother me one way or the other. One button does it all - one quick tap to make ice and one short push to clean the machine. Simple to clean, cycle takes 15 minutes, dump the water (pull to edge of counter and open plug on bottom, let drain in small jug or bowl. Then, rinse, repeat twice and let air dry overnight and it's ready to go and go and go again the next day. It really feels sturdy and solid. I'm thinking if the inside is built as good as the outside this will last a long time. I've been seeing Typhur products more often and I know they are a quality brand name.

Built for people who love nugget ice!
Color: Piano Black
If you love nugget ice, this machine delivers exactly what you’re hoping for - soft, chewable, restaurant-quality pellet ice at home, consistently and quickly. The biggest differentiator is speed and volume. It produces up to 35 lbs per day, and the first batch is ready fast. The ice texture is true crushed pebble/nugget style - not hard cubes disguised as “pellet” ice. It’s ideal for iced coffee, sparkling water, cocktails, and entertaining. The stainless steel exterior feels premium and modern on the countertop. Noise level is typical for a countertop ice maker, noticeable but not disruptive. It’s not silent, but it’s absolutely reasonable for the output.

Short life span
Color: Piano Black
We really liked this ice maker. The good-the water reservoir and ice basket are larger than in our last one, so we only refilled this one maybe once a day (family of 4). The ice didn't build up on the side and trigger the ice maker full shut off like our previous one. It is quieter than our last one too, and seemed to make ice just as fast. The bad-it doesn't turn itself back on as the ice melts and refills the water reservoir. The really bad-we've only used distilled and RO water in it. We've been fighting with it for a couple of months now to get it to make ice. We've cleaned it over and over with the cleaning solution. We also cleaned the vents as suggested with a vacuum and compressed air. It's to the point that it literally makes 2 ice cubes every time we start it, and that's it. We bought it 6 months, and we're giving up on it. We'll try another brand.

Almost Perfect
Color: Piano Black
Came from another ice maker and I miss two things: 1) size. This unit is tiny. It might be good if it’s just for you and maybe one other person, but for a family of four where everyone uses ice for their drinks and water bottles around the clock, this was constantly empty and needing more water. 2) the ability to start making ice on its own after there’s enough water. It has a sensor to tell you when it’s full of ice and it has a sensor to tell you when the water level is low, but it doesn’t have a sensor to tell it when the water has been refilled. You have to push the “ice making” button twice to get it to restart. Not a huge problem, but if you’re like me and leave your ice machine on 24hrs a day, you could come back to an empty ice machine after the ice in the basket melts. With my old ice maker, the machine would sense the water was low and stop. But then all the ice that was already made and in the basket would melt and fill the reservoir again and the machine would sense that and start back up on making a new batch small gripes, I know. Overall, it’s a nice, cute little ice maker and my kids love nugget ice.
