4.4 HEART RATE CONTROL WORKOUT OPERATION
Your Matrix treadmill offers a heart rate control workout mode.  The 
heart rate control workout mode allows the user to program their 
desired heart rate zone and maximum allowable incline and the 
treadmill will automatically adjust the incline based upon the user's 
heart rate.  The heart rate zone is calculated using the following 
equation:(220-Age)*%=targetheartratezone.Theusermustwear
a telemetric heart rate monitor or continually hold onto the contact 
heart rate grips for his workout. 
1) Choose TARGET HEART RATE by selecting the target heart rate 
workout button and press ENTER.  
2)Entertheuser'sageusingtheARROWKEYSortheNUMBER

3) Enter the desired percent of maximum heart rate using the 
ARROWKEYSortheNUMBERKEYPADandpressENTER.
4) Enter the user's weight (the user's weight is used to calculate 
the caloric expenditure value, providing an accurate weight helps to 
ensure an accurate caloric expenditure rating for each user) using

4.5 FITNESS TEST WORKOUT OPERATION
Your Matrix treadmill offers a variety of fitness tests - the Gerkin Firefighter Protocol, the Army, Navy, USMC, and USAF as well as the Physical 
Efficiency Battery (PEB). 
The Gerkin Protocol was developed by Dr. Richard Gerkin of the Phoenix (Arizona) Fire Department. It is a sub-maximal graded treadmill 
evaluation used by many Fire Departments across the United States to assess the physical condition of the firefighters. The test requires 
constant monitoring of the user's heart rate so the use of a telemetric chest strap is highly encouraged. The workout operates as follows:
WARM UP:Thewarmupis3minuteslongandrunsat3.0mph(4.8kph)and0%incline.
STAGE 1: At the 3 minute mark, the treadmill will gradually increase speed to 4.5 mph (7.2 kph). The actual test begins at 4.5 mph (7.2 kph). 
STAGE 2:Afteroneminute,thetreadmillinclinewillincreaseto2%.
STAGE 3: After one minute, the treadmill speed increases to 5.0 mph (8.0 kph).

evaluation remains at the stage where the target heart rate is exceeded, without any change to speed or incline.  If the heart rate does not 
return to or below the target heart rate, the evaluation ends and the final evaluation stage is recorded. If the heart rate returns to or below the 
target heart rate, the program continues at the point where it would have been had the program not stabilized for 15 seconds.  
TEST COMPLETION:  The test is completed when user's heart rate exceeds the target for more than 15 seconds or when the user completes
