Frequently Asked Questions - BB 3500 TRELOCK

How do I install the Trelock BB 3500 bike computer?

Mount the handlebar bracket using the provided zip ties. Attach the sensor to the fork and the magnet to a spoke. Route the wire carefully. Insert the battery, then place the computer unit into the bracket.

How do I set the wheel size on the BB 3500?

Measure your wheel circumference in mm (e.g., 2100 for a 700c road bike). Press and hold the SET button for 3 seconds, then use the MODE button to adjust the number and SET to confirm.

The display is blank. What should I do?

Check the battery. Replace with a fresh CR2032 coin cell. Ensure the battery contacts are clean. If still blank, reset the unit by removing the battery for 10 seconds.

How do I switch between km/h and mph?

Press and hold the MODE button for 5 seconds to enter unit selection. Press MODE again to toggle between km/h and mph, then press SET to save.

How do I reset the trip distance?

Press and hold the SET button for 2 seconds while viewing the trip distance (TRIP) screen. The trip distance will reset to zero.

Is the Trelock BB 3500 waterproof?

It has an IPX4 rating, meaning it is splash-proof. It can withstand rain, but do not submerge it in water or use a pressure washer.

What battery does the BB 3500 use?

It uses a CR2032 3V lithium coin cell battery. This is widely available at electronics stores. Expected battery life is about one year under normal use.

Why is my speed reading zero or erratic?

Ensure the magnet on the spoke passes close to the sensor (within 3mm). Check that the wire is not damaged and the sensor is aligned. Verify the wheel size setting is correct.

How do I replace the battery?

Remove the computer from its bracket. Open the battery compartment on the back (usually a small latch). Remove the old battery and insert a new CR2032 with the + side up. Close the compartment securely.

What does the AUTO function do?

The BB 3500 has an auto start/stop feature that pauses timing when the bike stops moving and resumes when you start again. This ensures accurate ride time recording.

TRELOCK®

INSPIRED GERMAN INNOVATION

The TRELOCK data systems of the Bike & Body computer line were developed to specifically cater for your needs. This line offers you a multitude of bike, altimeter, pedal stroke and pulse measurement functions, depending on the product features. The hardware, software and ergonomics of the products thoroughly meet the highest demands in terms of quality, convenience and performance.

An outstanding feature is the fully digitized data transfer between the various transmitter modules and the cycle computer developed by TRELOCK – RADIO SELECT®. The receiver of the cycle computer exclusively selects coded system data – data transfer without any cross talking effect. Interference due to mobile phones or training partners' cycle computers is not received.

Theft is pointless owing to the PIN coding.

The wireless wake-up function is a special function – ride off without switching on.

Data transfer to a PC via a USB interface is possible with the accessory set ZF 450.

The visual control system, large mono keys and the neatly arranged display with full text displays in eight languages allow very simple operation.

2.5 Setting the current time

• Press the SET button
• Change the digits by pressing the MODE button several times
• Confirm the individual digits by pressing the SET button

2.6 Entering and modifying the PIN – anti-theft protection

You can protect your cycle computer against foreign access with a PIN. Activation of the cycle computer is only possible in this case if the PIN is entered correctly. After adjusting the time and date, the user is transferred to the "Change PIN?" window. You can enter your own PIN here and subsequently modify it if necessary. If you do not wish to use any PIN, press the MODE button. Otherwise, after pressing the SET button, you will be asked to enter the former PIN (the factory setting is "0000"). In order to do this, press the MODE button until the appropriate digit appears and subsequently jump to the next position by pressing the SET button. The PIN is controlled. If the PIN has been incorrectly entered, "Wrong PIN" appears for approx. 3 seconds and you will be requested to make a new entry. If the PIN is correct, enter a new PIN of your choice as described above. After confirming the last position by pressing the SET button, the PIN must be re-entered. If repetition of the PIN is incorrect, you will be returned to the "Change PIN?" window. If you wish to dispense with safeguarding your cycle computer with a PIN, reset the PIN to "0000".

Please note your personal PIN on page 2, so that you can have it available if appropriate.

2.7 Entering and modifying the PIN time - energy-saving function

If the cycle computer, which is in sleep mode with the PIN function active (PIN not equal to 0000), is not awakened over a certain period of time, it can only be reactivated by entering your PIN. This period of time (PIN time) can be entered or modified in the "New PIN time?" window: After you have pressed the SET button, you will be requested to enter your PIN. After making a correct entry, you

will be transferred to "PIN TIME", where you can enter up to 240 min. The factory setting is 60 min. In sleep mode, only the time will be displayed until the PIN time elapses. After the PIN time elapses, the time display will also be faded out. If the PIN time is set to "0", this energy-saving function is deactivated and the time will be permanently displayed.

2.8 Logging in the pedal frequency

sensor(BB 2000, BB 3000, BB 4000)

• Log the pedal frequency sensor in by pressing the SET button
• Enter the code no. by pressing the MODE button (repeatedly)
• Confirm the individual digits by pressing the SET button
• Repeat the process for the other digits

After confirming with the SET button, the user is transferred to the "Pulse limits?" window. Before you now modify the upper heart rate limit, you should be aware that "Maximum" displays the upper heart rate limit with total exhaustion of your physical performance ability. This value is already calculated on the basis of the personal data that you have entered. You should not increase this value, or have your personal upper heart rate limit determined by your physician by means of a stress test. Calculation formula: 220 - age = maximum value

7.1 Training manager

Depending on the product features, your TRELOCK cycle computer offers a wide range of specific training options. You can, for example, determine

• how long you wish to train
- the minimum number of kilometres you wish to cycle
- the gain in altitude you wish to achieve (BB 3500, BB 4000)
• how many calories you wish to burn in a training session (BB 3000, BB 3500, BB 4000) or

In the "Pedal frequency" menu (BB 2000, BB 3000, BB 4000):

= the current pedal frequency is above the training limit entered.

- = the current pedal frequency is optimal for your training.

= the current pedal frequency is below the training limit entered.

In the "Heart rate" menu (BB 3000, BB 3500, BB 4000):

7.2 Putting the ZF 460 chest band on (BB 3000, BB 3500, BB 4000)

A Attach the elastic band to the sensor. The chest band can be adjusted to fit sizes M to XXL.
B Moisten the inside of both contact points on the right and left next to the sensor.
C Put the chest band on as illustrated. The TRELOCK logo on the transmitter must be legible and must not be upside down! Adjust the length of the elastic so that the chest band fits comfortably, but cannot slip during training.

Press the MODE button for 2 sec. and repeat the procedure if necessary until the main menu "Heart rate" appears on the display. If the chest band has been put on correctly, the heart symbol will now flash and the current heart rate will be displayed – you can now start to train.

Why is the speed incorrectly displayed?

A wrong wheel size has been entered.

Why is the altitude incorrect?

(BB 3500, BB 4000)

Barometric pressure has changed – altitude compensation is required.

Why is no speed or pedal frequency (BB 2000, BB 3000, BB 4000) displayed?

The distance between the sensor and the respective magnet is too great or the battery in the respective sensor is flat.

Why isn't the heart rate displayed? (BB 3000, BB 3500, BB 4000)

a) The chest belt is not correctly positioned.
b) The contact points on the sensor are not moistened or are dirty.
c) The sensor battery is flat.

Why does the display go dark or react sluggishly?

The operating temperature (5 °C – 50 °C; 40 °F – 120 °F) is too low or too high.

Why is the display pale?

The battery is flat and needs replacing.

Can my training partner's cycle computer interfere with my device?
