NVRAM Test
The NVRAM (Non-Volatile Random Access Memory) test will not erase all stored information such as user identification, and
all saved programs. The NVRAM is a computer chip that saves information even when the treadmill has been turned off.

TM
/ ENTER key.
2. Press the JustGo™/ENTER key to start the NVRAM test. The NVRAM test will perform automatically.

/ ENTER key. The EPROM TEST
will perform automatically.
• The display will show ‘‘EPROM IS OK’’ if the EPROM is intact and it will display a “CHECKSUM” code (for Bodyguard

• The display will show ‘‘EPROM IS NOT OK’’. This means the EPROM might be damaged.

Heart Rate Test
The heart rate test allows you to determine if the heart rate system (chest strap or hand grip) is working properly and that
the computer is displaying your heart rate signal during a program.
1. In the Diagnostics menu, select the “HEART RATE TEST” and accept it by pressing the JustGo
TM
/ ENTER key.
2. The top left display will show the signal received from the chest strap and the bottom window will show the hand grip
signal. Attach your heart rate chest strap. You do not need to step on the treadmill for this test, but simply stand near
the computer. Within a few seconds, your actual heart rate signal will be displayed on the screen. Do the same for the
hand grip system; put your hands on the two metal plates and wait for 10 to 15 seconds.
3. Press the CLEAR/STOP key to terminate the test.
