Slevio Timer Functions

The Slevio gym timer comes with 10 different functions.

I’ll break each function down below.

Clock

Clock mode displays the hour, minute, and seconds on the screen.

You can set it to 12 hour or 24 hour (military) format.

Custom Intervals

You can set up to 9 custom intervals with the Slevio gym timer.

Intervals are displayed with the letters “F” and “C” on the screen.

When first setting up the rounds, you’ll see the screen above with the number of rounds shown on the right side.

F stands for fitness, this is your workout timer.

The round number you’re currently on is shown next to the F.

C stands for cease, this is your rest period.

The round number you’re currently on is shown next to the C.

Countdown

Just like the name states, countdown just counts down from top to bottom.

Set a time, press start, and it’ll start counting down to zero.

Maximum countdown timer is 99 minutes and 59 seconds.

Countdown with Rounds (AMRAP)

AMRAP means as many reps as possible or as many rounds as possible.

With this setting you select a certain amount of rounds (F), select the time, and hit start.

The round number is shown on the left in blue.

The timer will countdown to zero, then start the next round from the top immediately without any rest period.

Counter (Count Up)

This is the opposite of countdown.

Set a time, press start, and it’ll start counting from zero up to your set time.

You can count up from 0 to 99 minutes and 59 seconds.

Counter with Rounds (EMOM)

You can use this function for EMOM workouts.

EMOM means you do a number of reps every minute on the minute but you can select more than a minute per round.

With this setting you select a number of rounds (F), select the time, and hit start.

The round number is shown on the left in blue.

The timer will count up, then move to the next round immediately without any rest period.

Stopwatch

This one’s self explanatory.

The timer counts up just like a stopwatch.

Alarm Clock

The alarm clock setting works just like a regular alarm clock.

Set a time when you want it to ring and you’re done.

A red bell on the screen tells you that the timer is on (seen right next to the blue 8).

Countdown Settings

The Slevio gym timer comes with a 10 second countdown by default.

This gives you a visual and audible cue to get ready before your workout starts.

You can adjust the countdown from 0 to 10 seconds.

The final 3 seconds give you an audible beep (if the volume is on).

Volume Settings

This feature lets you adjust the volume of the timer.

Anytime you press a soft key, the timer beeps.

The timer also beeps whenever it reaches zero or a set time.

It’s adjustable from 0 to 5, 5 being the highest volume.

If you choose 0, the sound is disabled.

Slevio Pros & Cons

Pros

Portable: At less than 7″ long, you can take the Slevio timer with you anywhere

Price: You can’t beat the $60 price tag with all its features. Other brands charge twice as much for the same.

Multi-functional: With 10 functions, you get a whole lot of timing options to cover your workouts.

Battery operated: Equipped with a 30 hour battery life so you don’t need wall outlets near your workout station.

Strong magnet: The magnetic spine can attach to your weight rack, iron plates, your car, and anything metal.

Cons

Lanyard: Lanyard can be difficult to attach to the timer but I don’t think it’s even necessary.

Instructions: The instructions manual can be a bit confusing. Watch my video above to make it easier.
