Section One - Things You Should Know

Right, Left, Front, and Back Conventions

In this manual, right, left, front, and back are from the perspective of a user standing on the EFX

544, facing the display enclosure.

Warning and Caution Statements and General Safety Guidelines

Warning statements indicate a particularly dangerous activity. Warning statements you will find in

this manual include:

• To remove power from the EFX 544, the power cord must be disconnected from the wall

outlet. Always ensure that the EFX 544 is unplugged from the wall outlet when you inspect

or adjust the EFX 544, or when you isolate, remove, or replace an EFX 544 component.

• Removing the covers exposes high voltage components and potentially dangerous

machinery. Exercise extreme caution when you perform maintenance procedures with the

hood removed.

• During service operations you will be very close to moving machinery and high voltage

components. When you perform maintenance procedures with the covers removed, remove

jewelry (especially from ears and neck), tie up long hair, remove neck ties, and do not wear

loose clothing.

• When the EFX 544 is operating, the capacitor will hold a lethal amount of charge. Do not

touch the capacitor as serious injury or death might result.

• When the EFX 544 is turned off and the power cord is removed from the wall outlet, the

capacitor will hold voltage for 30–60 seconds. Allow the capacitor to discharge for a period

of one minute before you touch or work near the capacitor. Do not attempt to discharge the

capacitor by any other means.

• Exercise caution when touching any wire or electrical component during EFX 544 operation.

• Exercise extreme caution when working with the flywheels and/or the stairarms. Because of

the mass of the flywheels, serious injury may result if fingers are pinched between the

flywheel spokes and the stairarms.

• The flywheel is very heavy. Be prepared for the weight of the flywheel when it comes off of

the pulley shaft.

Caution statements are intended to prevent damage to the EFX 544 as a result of the current

activity. Caution statements included in this manual are listed below:

• Notice the orientation notch on the PROM (U3). These components must be positioned with

the same notch orientation.

• When it is necessary to lift the EFX 544, ensure that the EFX 544 has adequate support. Do

not lift the EFX 544 by the front cross-member.

Safety guidelines you should know and follow include:

• Read the owner’s manual and follow all operating instructions.

• Operate the EFX 544 on a solid, level surface. Locate the rear of the EFX 544 at least four

feet from walls or furniture. Keep the area behind the EFX 544 clear.

• Visually check the EFX 544 before beginning service or maintenance operations. If it is not

completely assembled or is damaged in any way, exercise extreme caution while operating

and checking the EFX 544.

• When operating the EFX 544, do not wear loose clothing. Do not wear shoes with heels or

leather soles. Check the soles of your shoes and remove any embedded stones. Tie long

hair back.

• Do not rock the unit. Do not stand or climb on the handlebars, display enclosure, or cover.

• Do not set anything on the handlebars, display enclosure, or cover. Never place liquids on

any part of the EFX 544.

• To prevent electrical shock, keep all electrical components, such as the power cord and

circuit breaker away from water and other liquids.

• Do not use accessory attachments that are not recommended by the manufacturer-such

attachments might cause injuries.

Procedure 3.1 - Software Access Codes

Over the years the codes used to access the various software diagnostics features have

changed. Currently we are using a “standardized” set of access codes. These codes will be used

on all current and future software. In using the standardized access codes the keys are

numbered left to right with key #1 on the far left and key #7 on the far right. If the standard access

codes do not function on the unit being tested refer to the appropriate old access codes listed

below. The standard access codes use all sequential key presses, the old access codes use

simultaneous key presses.

Standard Access Codes

Diagnostics Keys RESET,5,1,7,6,5,7,6,1

Odometer Keys RESET,6,5

Club Settings Keys RESET,5,6,5,1,5,6,5

Old Access Codes

Diagnostics Keys Ramp ▲, Resistance ▼, Resistance ▲

Odometer Keys Ramp ▲, Resistance ▲

Club Settings Keys Resistance ▲, Quick Start/Change

Procedure 3.2 - Accessing the Diagnostic Software

The EFX 544 diagnostic software cycles through the following tests:

• Performing LED Diagnostics

• Checking the Lift Calibration Number

• Heart Rate Diagnostic

• Performing the Keypad Test

Procedure

1. Plug the power cord into the wall outlet, then turn on the EFX 544 with the circuit breaker.

2. Press the RAMP ▲,RESISTANCE ▼and RESISTANCE ▲ keys, simultaneously or keys

RESET,5,1,7,6,5,7,6,1, sequentially.

3. Watch the upper display as the LED test progresses. The test is programmed to display the

following LED illumination sequence:

a Every LED on the left display window illuminates simultaneously.

b Diagonal lines of illuminated LED’s sweep across the left display window.

c The right display windows illuminate, then decrement from 8.8.8.8 to 0.0.0.0.

d The function LED’s illuminate simultaneously and then extinguish.

e Each function LED illuminates separately and then extinguishes.

4. With LIFT displayed in the right display window, watch the right display window (shown in

Diagram 3-1). Press the RAMP ▲and RAMP ▼keys. Verify that the lift calibration number

increments and decrements as the RAMP keys are pressed.

5. If you do not observe the LED illumination sequences described in Step 3...

Procedure 3.4 - Club Settings

Selecting United States standard units causes information to be displayed in miles. Information is

displayed in kilometers if metric units are selected. After you select a measurement standard, the

software accumulates and records workout information in the units of the measurement standard

selected.

The 120 Volt/240 Volt setting does not change the input operating voltage of the EFX 544. It

changes the resistance levels to match the input operating voltage. Therefore, this setting must

match the input voltage of the EFX 544. If the setting does not match the input voltage, the

resistance levels will be incorrect.

6. The maximum workout time is displayed on the left display window.

7. If you wish to change the maximum workout time...

Procedure 3.5 - Documenting Software Problems

When a problem is found with either the software or upper or lower PCA’s, record the information

listed below. If you isolated the problem to either the PROM, upper PCA, or lower PCA, include

the information you recorded with the malfunctioning PROM or PCA when you ship it to Precor.

When a problem occurs, record the following information:

• Model and serial number

• Software version number

Note:

Look at the PROM (U3) mounted on the upper PCA. A label on U3 indicates the software version

number. The part number of the PROM indicates the version number.

• User and program number running when the problem occurred

• A description of:

a What happened or failed to happen.

b The action taken by the user just before the problem occurred.
