Product Information
Facts
NOTE! Before you start using the recumbent - remember to remove any transport protection and protective tape on the flywheel.
Technical details
Initial operation
RT2 is mechanically calibrated in the factory. The user may still want to check this. For the procedure, see section "Calibration".
If you use power adaptor (optional): First, connect the power adaptor to the power connector on the right side of the recumbent, see Fig: Overview. Then plug the power adaptor into the wall outlet.
Perform the electrical calibration as specified in section
"Calibration”. Test by pedalling the recumbent. If the recumbent works properly, it is ready for use.

Monark bikes measure the effect of the flywheel, so it will be a friction of 6-8% if you measure the impact of the pedals (measure the effect of the crankshaft, the difference is 4-5 %). These percentages will be primarily due to friction in the chain, pedals and bearings.
RT2 is set to measure the workload at the flywheel.
The bike can be set to work with effect in the pedals / crankshaft (the cycle constant).
Technical data power adaptor (accessory)
Output voltage: +9 V DC
Current: 500 mA
Polarity: Minus (-) in the middle of connector. See Fig:
Polarity.
(Art. No. 9384-650, USA Art. No: 9384-62)
Calories
There have been different theories on how to calculate this, since it depends on several factors and this means that it can only be seen as an estimate.
Fig: Polarity
As a standard calculation, when we display calories on our calibrated bikes, we use: 1 minute with 100W gives 7 kcal. It is easy to convert watts to calories if it was on the flywheel, the formula is 1W=0,2388x10
-3 kcal/s with four decimals. But when you normally show calories you want to show the total amount of calories your body has used during your training, not only the calories "burnt" on the flywheel.
Serial number
The serial number is located on machine plate (5) according to Fig: Overview.
We have chosen the formula given above that we think complies with the results given for a standard cycle position.

Distance seat - handlebar 80-470 mm
Recumbent adjustments
When you ride on the recumbent you should adjust the distance to the pedals so that you get a comfortable seating position. You can adjust the seat longitudinally by lifting the lever on the right side and push the seat forward / backward. Once you find the correct position, release the lever and make sure it locks (a click is heard).
To change the seat-back tilt, pull out the sprint to the right and help with the other hand to change the tilt. Once you find the correct position, release the lever and make sure it locks (a click is heard). See Fig:
Adjustments.
Daily check
The following procedure ensures that the recumbent works for daily use.
• Check the HR function if you use chest belt, see section, on 'Heart rate'.
• Check the braking force by putting on a certain workload and check that the load is applied.
• Test by pedalling and check that a reasonable rpm is obtained - verify by a clock. Feel if the pedals move smoothly. Listen for unusual sounds. Adjust if necessary.
• Adjust the seat and make sure it is securely attached and that the adjustment is working properly.
• Make sure the support legs are in position by rocking the bike. Tighten if necessary.
If something unusual is found during the daily inspection that you cannot resolve, please call customer service.

Pulse function
The user's heart rate can be measured with pulse sensors in the handles of the seat (some models) or with chest belt that detects your pulse from the heart.
Heart rate monitoring requires that the chest belt is correctly placed. Make sure that your skin is clean where the chest belt should be placed. When it is correctly fitted the logo on the belt will be central and readable, outward and upright, by another person.
The chest belt should be secured at a comfortable tension around the mid section, just below the breast muscle, see Fig: Placement chest belt. Moisten the electrodes before use, see Fig: Electrodes on the back
of the chest belt.
Pairing display and chest belt
Normally the display connects to the first ANT+ chest belt in "short range" and shows the heart rate until the chest belt is outside the "long range". If there is no
ANT+ chest belt but a 5K chest belt in "short range", the heart rate from the 5K chest belt is displayed until the signal is lost.
ANT+ is prioritized and the first choice of the display.
5K is discriminated, but after 30 seconds with only
5K the display is locked to this chest belt as long as you do not lose the signal.
NOTE! Electromagnetic waves can interfere with the telemetry system. Cellular phones are not allowed to be used near the bike during test.
Monark Exercise AB recommend that you use an ANT+ chest belt for best function.
Pulse standard (chest belts)
The following pulse standard / chest belts can be used:
• Standard, uncoded 5K chest belts (5-5.6 kHz)
• Chest belts with ANT+
Short range ANT+: 0.6-0.8 m
Long range ANT+: 4-5 m
Range 5K: 0.8 m (31 ½")

The meter has the following functions:
• Settings for different units of measurement
• It is possible to calibrate the meter to get the correct workload
• Personal data such as age, max pulse, weight and gender can be set
• USB port for continuous output of data to an external computer
• The meter also shows current pulse as percentage of max. HR
• The workload is rpm independent
Connecting to PC
You can connect a PC to the display. This is done via the USB connector (8) in Fig: Display. The display will show "PC" and the current RPM. Although HR is displayed if you use chest belt. In the PC software your values are logged, but you cannot change workload, it is change by the workload lever.
An appropriate software is available to download from our website: www.monarkexercise.se.
Sleep mode
Sleep mode is activated after 10 minutes if you do not press any button or if no rpm is recorded. This is to save battery power.
All settings are saved, but the personal settings are erased (to protect your personal privacy).
The meter wakes up when you press any button or if rpm is recorded. The meter goes directly to 'Quick start' (see separate section).

at different workloads is:
0.2333 ... l / kpm = 0.01428 L / W (2.8 l / min at
1200 kpm)
This is according to Astrand's table between 150 W and 300 W, and a good approximation for 15-700 W and a cadence of about 50-65 rpm.
Press ENTER (for 5 seconds during the test) and a new test is started with the same settings.

• No batteries in the meter
• No current in the outlet (if power adaptor is used). Check the fuses.
• Check cables and connections.
• Correct power adaptor? Check that the transformer information (voltage, current, polarity, AC / DC) in section "Facts" complies with the transformer which is used.
• Check calibration.
• Check that brake belt is hooked in the spring.
• Check that the battery is alright in the chest belt, moisten your thumbs and click on the electrodes, a low clicking sound will be heard at the battery cover, alternatively that the heart rate is displayed in the computer software.
• Make sure the belt fits correctly on the test person,
see Fig: Placement of chest belt
in section "Heart Rate", and that the strap is sufficiently tightened. Moisten the electrodes, in severe cases it may be necessary to use gel alternative, one drop of dish washing liquid mixed in water. Pulse signal strength varies from person to person. Try the belt with a person known to have a good pulse wearing a chest belt.
• Make sure there are no loose cables. Use another HR receiver (HR watch or test bike monitor) to check the chest belt.
• Use an external unit, for example a HR watch, to check if it also indicates an irregular pulse. If this is the case, there is probably disturbance in the room. The disturbance may be electronic fields from power cables, elevators, lamps etc. or other electronic devices which are too close (e.g. cell phones).
Move the bike to a different location in the room or change rooms. If an irregular HR remains it should be checked manually. If the HR remains irregular at work the person's health should be examined.
• Check cable.
• The potentiometer shaft is not attached to the pendulum shaft, tighten the screw.
• The potentiometer is misadjusted.
• The pedals are not tight. Tighten them or change pedals.
• The crank is loose. Check, tighten.
• The base bearing is loose. Contact your dealer for service.
• Check that the carriage block is taken off and that nothing is against the crank, chain, or wheel except the brake belt.
• Loosen the chain.

Service action:
• We recommend isopropyl alcohol to disinfect the surface of the bike. Use a damp, but not wet cloth to clean the surface you wish to disinfect.
• Surface treatment with a rust inhibitor, especially when the bike is clean and the surfaces are dry This is done to protect the chrome and zinc parts as well as the painted parts (4 times per year).
• Check now and then that both pedals are firmly tightened. If not the threading in the pedal arms will be damaged. When the ergometer is new it is important to tighten the pedals after 5 hours of pedalling (check this 4 times per year).
• Check that the pedal crank is secure to the crank axle (4 times per year).
• Be sure that the pedals are moving smoothly, and that the pedal axle is clear of dirt and fibres (4 times per year).
• When cleaning and lubricating be sure to check that all screws and nuts are properly tightened (twice a year).
• Check that the chain is snug and there is no play in the pedal crank (twice a year).
• Check that pedals, chain and freewheel sprocket are lubricated (twice a year).
• Be sure that the brake belt does not show significant signs of wear (twice a year).
• Check that the handlebars and seat adjustment screws are lubricated (2 times per year).
• Be sure that all moving parts, crank and flywheel are working normally and that no abnormal play or sound exists. Play in bearings causes fast wearing and with that follows a highly reduced lifetime.
• Check that the flywheel is placed in the center and with plane rotation.
• Grind the brake belt contact surface, see section
"Brake belt contact surface" (once a year).

Batteries
If the display is battery-operated, the batteries are in a separate package at delivery. If the storing time has been long the battery power can be too low to make the computer act correctly. Batteries must then be changed.
Manual pendulum bike / exercise bike:
To loosen the brake belt on the bike remove all tension.
Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.
Flywheel bearing
The flywheel bearing is long-term greased and requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.
NOTE!
When replacing the brake belt it is recommended to clean the brake surface. See ”Brake belt contact surface”.
Brake belt contact surface
Crank bearing
The crank bearing is greased and normally requires no supplementary lubrication. If a problem arises, please contact your Monark dealer.
Deposits of dirt on the brake belt and on the contact surface may cause the unit to operate unevenly and will also wear down the brake belt. The contact surface of the flywheel should be smoothed with fine sandpaper and any dust removed with a clean dry cloth.
Transportation
During transport the brake cord should be tightened to prevent it from falling off the flywheel.
Remove any potential covers and all workload on the brake belt and then remove it. Grind with a fine sand paper. Grinding is easier to perform if a second individual cautiously and carefully pedals the cycle.
Replacement of brake belt
To replace the brake belt remove covers if necessary.
Make sure that the belt is loose.
Irregularities on the brake belt contact surface are removed by means of a fine sand paper or an abrasive cloth. Otherwise unnecessary wear on the brake belt may occur and the unit can become noisy.
Pendulum bike with engine:
To loosen the brake belt on pendulum bikes with engine, connect power to the unit and raise the pendulum to 4 kp. Hold it there until brake belt is loose. Please note how the belt is assembled. Remove it from the bike. Attach the new brake belt and assemble the bike in reverse order.
Always keep the brake belt contact surface clean and dry. No lubricant should be used. We recommend replacing the brake belt when cleaning the contact surface. In regard to assembly and adjustment of the brake belt, see ”Replacement of brake belt”.
Weight basket bike:
To loosen the brake cord on cycles with a weight basket set the basket to its upper position. Loosen the lock washer that is holding the cord and remove it from the tension center. Loosen or cut off the knot on the other end of the cord and then remove the whole cord from the bike. When assembling a new brake cord, first enter one end into the hole in the tension center, and tie a knot and let the knot fall into the bigger part of the hole. Lock the end of the cord with the lock washer.

Chain 1/2“ x 1/8“
Check the lubrication and tension of the chain at regular intervals. In the middle of its free length the chain should have a minimum play (3) of 10 mm (1/4 inch). See Fig: Chain adjustments. When the play in the chain is about 20 mm (3/4 inch) the chain must be tightened. Otherwise it will cause abnormal wear of the chain and sprockets. Therefore it is always recommended to keep the chain play as small as possible. Loosen the hub nut (2) on both sides and tense the chain with the chain adjuster (1) when needed.
When the chain has become so long that it can no longer be tightened with the chain adjusters it is worn out and should be replaced with a new one.
To adjust or replace the chain, remove covers if required.
To adjust the chain the hub nuts (2) should be loosened. Loosening or tightening the nuts on the chain adjusters (1) will then move the hub and axle forward or backward. Then tighten the nuts on the hub axle again. See Fig: Chain adjustments.
To replace the chain, loosen the chain adjusters as much as possible. Dismantle the chain lock (6) and remove the chain. Use pliers to both release the lock washer and mount it again (4). Put on a new chain and assemble the chain lock. The spring of the chain lock should be assembled with the closed end in the movement direction (5) of the chain. See Fig: Chain
replacement.
NOTE!
At assembly the flywheel has to be parallel with the centerline of the frame. Otherwise the chain and sprockets make a lot of noise and wear out rapidly.

Freewheel sprocket
When replacing the freewheel sprocket remove frame covers if necessary. Remove the chain according to section ”Chain 1/2” x 1/8””.
Loosen the axle nuts and lift off the flywheel. Remove the axle nut, washer, chain adjuster and spacer on the freewheel side. Replace sprocket-adaptor and assemble the new parts in reverse order according to the above.
NOTE!
Do not tighten the axle nut completely. It must be possible to loosen the adaptor-sprocket half a turn.
The sprocket should be lubricated with a few drops of oil once a year. Tilt the cycle to make it easier for the oil to reach the bearing. See Fig: Lubrication.
