situation, remove the e-stop key from the treadmill and the running belt will come to a stop.
Safety Sentry
Safety Sentry uses display feedback to determine user presence. If a user is not detected within 10
seconds, the display beeps and inquires Run? (LED console) or Are you there? (E3 View console).
Page 52 of 79
Cybex 525T Treadmill Part Number LT-24018-4 H

The treadmill will use every sensor available to determine a user is still on the belt before asking if you
are present, then shutting it off. If the user is lighter than 100 lbs. (45 Kg), the motor drive may not be
able to determine they are on the belt. In this instance, the treadmill can only rely on the key inputs, or
the heart rate to establish your presence. It is advisable for lighter users to take advantage of the wireless
heart rate feature to avoid triggering the Safety Sentry.
An unattended, running treadmill can create an unsafe environment for a user. The Safety Sentry feature
is intended to allow the treadmill to stop the running belt when the treadmill is unattended. To avoid the
treadmill running unattended, follow these steps:
1. At the end of your workout, verify that the running belt is stopped by visually checking the Cybex
logo on the running belt, it should not be moving.
2. If the belt is moving, place feet on both sides of the top step and press STOP or remove the e-stop
key from the treadmill.

Meaning of % Grade
A 1% grade is not the same as a 1 degree incline. The % grade is the relationship of the measurement
of rise over the measurement of run (also called slope). For example, a 1 foot (meter) rise in height over
a length of 100 feet (meters) is a 1% grade. Expressed as a mathematical formula, the grade is calculated
as follows: 1 ft. (m) / 100 ft. (m) = 0.01 = 1%
With respect to treadmills, the percent grade is roughly equal to the increase in height (rise) of the
treadmill divided by the length (run) of the treadmill.
The degree of incline can be related to % grade by taking the Arctangent of the grade. For instance,
15% grade is equal to 8.53 Degrees (ArcTan(.15)=8.53°). The opposite is true to determine % Grade
from Degree of incline (Tan (8.53°)=.15).

7. Check the belt tension after the running belt has been centered.
Make sure the running belt tension is tight enough so that the running belt does not slip or hesitate
when stepped on. Walk on the treadmill at 3.5 - 4 mph (5.6 - 6.4 kph) and every 4th to 5th step throw
your weight into your step to feel if the running belt is slipping. If slipping is felt, confirm it is the
running belt slipping and not the drive belt. With the hood cover removed, observe movement at the
drive belt and front roller.
Do not over tighten the running belt. Over tightening the running belt can cause the belt to stretch
and require replacement. Continue procedure until running belt stops slipping.
8. Check running belt for centering position.
If running belt is not centered, perform steps 5 and 6.
Check Running Belt and Deck Surfaces
The running belt and deck should be checked periodically for any excessive wear. In an effort to make
sure that the running belt operates properly, visually inspect the belt often to make sure that there are
no tears or fraying in the belt material. The running belt should be replaced every 15,000 miles (24,140
km). The running deck should be flipped every 15,000 miles (24,140 km) and replaced every 30,000
miles (48,280 km). A service prompt will appear at this interval and the parts will need to be replaced.
Tools Required
Phillips screwdriver
Disconnect external power source
1. Toggle the on/off (I/O) power switch to the off (O) position. The on/off (I/O) power switch is located
under the front end of the unit, or on the front right side panel.

7 - Hill Interval 1:3
This workout utilizes a one minute work interval followed by a three minute rest interval. The rest intervals
are of a higher incline that those found in the other Hill Interval workouts, and therefore require a longer
recovery period.

8 - Cardio
This workout is designed to maintain a high total demand using two four-minute segments of alternating
incline. This allows prolonged intervals that take advantage of long-term energy systems and total
aerobic capability when associated with speeds that require a high sustained cardiovascular demand.

9 - Heartrate Control (E3 View Monitor Option)
Note: This workout requires the user to wear a 5 KHz Polar
®
or compatible heart rate transmitter
belt. The Heart Rate Control workout (HRC) cannot be selected on the control console unless it
detects a heart rate signal. The HRC workout will not work with the cardio touch contact heart
rate system.
After selecting the HRC workout, the treadmill will prompt you for workout time, weight, age, and target
heart rate. Your age is required to estimate the proper range of heart rates. The target heart rate is
calculated by the formula: 208 - (0.7 x Age). You will then have the option of adjusting the suggested
target heart rate selected either up or down. Select a target heart rate which will allow you to exercise
comfortably and safely while at the same time allowing you to reach your training goals. If you are unsure
of what to select as your target, consult your physician or a physical training professional, After starting
the HRC workout, the treadmill will attempt raise your heart rate to your target within 3 to 5 minutes.
The treadmill will emphasize using elevation of the treadmill deck first to achieve higher workloads and
thus higher heart rates; this is done to maximize the use of a walking gait, which is safer and more
comfortable for many users. As a result, many users will spend nearly the entire workout at elevation
up to 12% grade. After reaching your target, the treadmill will attempt to keep you there within 5 beats
per min. As you tire, the treadmill will compensate by reducing elevation, speed or both. A two-minute
cool-down is built in at the end of the workout.
Method of HRC workout:
User selects heart rate target in the initial start of workout or accepts the suggested target of the formula:
208 - (0.7 x Age). This target heart rate is extremely important for more reasons than just the
establishment of the target itself. It also makes an assumption of the general fitness level and controls
several aspects of how quickly the elevation and speed will be adjusted. As an example, the starting
speed for a selected target of 120 bpm (beats per minute) will be 2 mph. The starting speed for a selected
target of 140 bpm will be 3.5 mph. In between those selected targets the starting speed will be proportional
to the difference between 2 to 3.5. The workout will also be modified depending on what the selected
target is at the start of the workout. This means someone with a higher selected target will get faster
changes in speed and grade than someone with a lower target. This has the effect of getting the more
fit user to their selected target faster without overshooting the target for someone with a lower fitness
level. After the starting speed is attained by the treadmill, it will then increase the elevation every 15
seconds up to 12% grade or until the computer senses that the user is getting close to approaching
their target heart rate. Since the control is somewhat predictive in nature, it will leave ample room for
the user's heart rate to catch up to the increasing load. If the target heart rate is not attained at the load
level of the start speed at 12% grade, then the treadmill will start increasing speed every 15 seconds
up to 4 mph or until the computer senses that the user is getting close to approaching their target heart
rate. If the user is still not at the target, the treadmill will increase speed to 5 mph and drop the elevation
down to 8% grade. This is done because the speeds between 4 and 5 are difficult for the user because
it is too slow to jog and too fast for many to walk. The drop in elevation compensates somewhat for the
larger increase in speed. The system will then increase the speed of the belt every 15 seconds up to
the maximum speed of the treadmill or until the computer senses that the user is getting close to
approaching their target heart rate. At any time if the users heart rate exceeds the target, the load will

be decreased in the same order it was increased to ensure that the rate is stabilized at or below the
target. When the time period is reached that is two minutes before the selected total time of the workout,
the system will go into the cool down mode. This cool down will be similar to the cool down protocols in
all the other workouts on the treadmill.
During the control period, the user has limited control over speed and elevation. Within the initial elevation
climb segment up to 12 % grade, the users may vary elevation but not speed. Within the other segments
the user can vary speed but not elevation. The user's selections are not persistent, however. At the next
15-second mark, the controller as described above will generally choose a new speed or elevation. The
user is in fact advancing or retarding the action of the servo.
If at any time the heart rate signal is lost, the system will make no changes in load until such time as
the HR signal is regained. If the heart rate signal continues to be lost (no stable HR) for a time period
exceeding one minute, then start the cool down profile regardless of what the time period is.
