5. General default settings
5.1 Selection of language
Once the computer (by removing the plastic tab) has been activated, you automatically access the "Sprache?" (Language) menu. By pressing the SET button, you access the language selection option. Use the MODE button to choose one of the eight languages shown (German, English, French, Dutch, Spanish, Italian, Russian or Polish) and confirm your choice via the SET button.
5.2 Choice between km/h and m/h
In the "Dimensions?" menu, "km/h" is pre-set as the standard unit. If you wish to accept this default setting, press the MODE button.
To change it to "m/h", press the SET button. Then use the MODE button to choose between "m/h" and "km/h" in the "Unit Speed" window. Confirm your choice via the SET button.
5.3 Choice between °C and °F (only FC 840, 845)
Use the MODE button to choose between "°F" and "°C" now. Confir rm your choice via the SET button.
5.4 Setting(s) of wheel size(s) (FC 830, 840, 845)
You can use your cycle computer on 2 cycles – even if the wheels are different sizes. To do this, you need a separate holder and sensor for each cycle. For FC 830/840, you need Art. ZF 406 Uni-Base, ZF 435 transmitter, ZF 50 magnet. For FC 845 you will need Art. ZF 410 Night-LightBase + magnet, ZF 435 transmitter. Press the SET button to make or change the settings for cycle 1 or cycle 2 in the "Settings for cycle" window. Use the MODE button to select "Cycle 1" or "Cycle 2", then press the SET button to confirm.
5.5 Entering the code number
In the “Code No. 1” bzw. “Code No. 2” window, enter the 4-digit code of the sensor to register this on the computer. Smooth, uninterrupted communication between the computer and the sensor is assured by the Radio Select technology only once the sensor is registered. If the cycle or computer is stolen, the computer is of no use to the thief.
You will find the code number on a peel-off sticker on the sensor. You should remove the sticker and stick it in the instruction manual.
Press the MODE button repeatedly until the first digit has been correctly entered, then press the SET button to confirm. Repeat the procedure for the each of the other digits.

5.6 Setting(s) of wheel size(s) (wheel circumference)
Under “Wheel Size 1” or “Wheel Size 2” (only for FC 830, 840 845), you should now enter the wheel circumference of your bike. This can be seen from the wheel size data shown on the side of your tyre. Please consult the table shown on P. 55 for the appropriate 4-digit number.
Next press the MODE button until such time as the appropriate digit appears, then use the SET button to move to the next digit. Once you have confirmed the fi nal digit, you automatically reaccess the "Set Wheel" window.

5.7 Setting the current time
If you wish to change the time, press the SET button. One after another, hours, minutes and seconds (start automatically after confirmation of minutes) can be changed via the MODE button. Use the SET button to confirm your entries and to move to the next digit.
5.8 Entering and changing the PIN anti-theft protection
You can use a PIN to protect your cycle computer from misuse by unauthorized people. The cycle computer cannot be used unless the correct PIN is entered. Once the time has been set, you automatically access the "Change PIN?" window. Here you can enter your own PIN and, if necessary, subsequently change it. If you don't wish to use a PIN, press the MODE button. Otherwise, after pressing the SET button, you will be asked to enter the old PIN (default setting is "0000"). To this end, press the MODE button until such time as the appropriate digit appears and then use the SET button to move to the next digit. PIN input is monitored. Should the PIN have been entered incorrectly, the message "Wrong PIN" appears for approx. 3 seconds and you will be asked to re-enter the PIN. If the PIN is correct, input a new PIN of your choice as described above. Once the last digit has been confirmed via the SET button, PIN entry must be repeated. Should the repeat PIN entry be incorrect, you will return automatically to the "Change PIN?" window. Note down your personal PIN on Page 68 so that it is readily available if required!
5.9 Entering and changing the PIN time
If the bike computer is in Sleep mode and is not ‘awakened’ for a set time, it has to be reactivated by entering your PIN. The period concerned (PIN Time) can be (re)set in the “Set PIN Time” window – after you have pressed the SET button, you will be asked to enter your PIN. After correct PIN input, you automatically access “PIN Time” where you can enter the time of your choice up to max. 240 minutes. If you wish to dispense with the securing of your bike computer via a PIN, then set the PIN time to “000”.
An energy economy function is linked to the PIN-time setting. The PIN-time default setting is 60 min. and the PIN default setting "0000". As such, the clock is displayed in Sleep for 60 min., after which time the clock display shuts down. This period of time can be adjusted as described above. If the PIN time is set at 0, the energy economy function is deactivated and the clock is displayed on an ongoing basis.
If a PIN is set at "0000" and a PIN time at more than 0, the energy economy function and the PIN enquiry are activated. This means that, once the PIN time has elapsed, the clock display shuts down and the computer can only be reactivated via PIN input.
6. Main menus
Press the MODE button to move between the main functions (menus) - see 6.1 - 6.9. To enter figures (time, counter settings, etc.), repeatedly press the MODE button until the digit you want is displayed, then press the SET button to move on to the next digit. When you have completed your entry of the last digit, press the SET button to confirm.

By pressing and holding the SET button in the "SET" menu for 3 seconds, you then have the option of correcting your default settings and making further settings. Pressing the MODE button brings you automatically to the menus "Clock?" "Wheel Size?" with its submenus "Bike 1" and "Bike 2" (not applicable to FC 820) and "Total km" one after the other. Press the SET and MODE buttons simultaneously for 3 seconds to move to the general default settings (P. 48, Point 5.1.ff).
7. Training
7.1 Targeted training
Your TRELOCK bike computer gives you a wide range of options for training in a targeted manner. You have the possibility, for example, of monitoring
• how long you train for
• how many kilometres you cover
• how long you need to cover a certain distance.
Via the symbols „▲“, „●“ and „▼“ on the display, you are able to monitor the intensity of your training session on an ongoing basis.
▲ = the current speed is higher than the average speed on the current lap/stage
● = the current speed equates to the average speed on the current lap/stage
▼ = the current speed is lower than the average speed on the current lap/stage.
