12. Device operation

Operation from the app

From the "Control" tab of the main screen, you can perform the following operations.

  1. Adjustment of the detection sensitivity (HIGH: high sensitivity, MID: medium sensitivity, LOW: sensitivity suitable for cycle racks)
  2. Periodic transmission on/off: the device will periodically acquire your location even when no movement is detected.
  3. Notification on/off: Turns smartphone notifications on or off.
  4. Location: Displays a map screen that shows your location.
  5. Device Settings: Configures advanced settings for the device.
  6. Locked status change panel

*The device can only be operated while connected via Bluetooth.
*The alarm triggering time and frequency limits, regular transmission intervals, etc. can be set in the "Device Settings".
*Regular transmissions consume a lot of battery power and should be avoided at all times or the interval should be changed to 180 minutes or more.

Operation on the device

If the AlterLock device and the smartphone are within a few meters of each other while in a Bluetooth connection, a short press of the button on the device can switch to the locked or unlocked state.

From [Device Settings], go to [Device], and tap [Adjust] to reset the switch response sensitivity.

Operation on the device side can be used if the Bluetooth reconnection with the smartphone is automatic; it can be used with the iPhone and most Android models, but depending on the smartphone's settings and power saving features, it may not reconnect.

Reboot the device

If the device doesn’t reconnect with your smartphone or isn’t working properly, you can reboot it by holding the button down for at least 10 seconds.
There is no security issue as the lock status and settings will be maintained after a reboot.


13. Device operation check

After registering the AlterLock device, ensure that the anti-theft alarm and notification features are operational.

  1. With the device nearby, open the main screen and tap 𝗨𝗻𝗹𝗼𝗰𝗸.
  2. When the lock status display switches to "Lock", the accelerometer is enabled.
  3. If the device detects movement above a certain level, an alarm will sound.
  4. The first alarm sound is set to a relatively low warning tone. If you make another movement a few seconds after the alarm has sounded, the alarm will sound at maximum volume.
    *If you want to set the alarm to sound at maximum volume from the first time, or change the alarm sounding time, please go to "Device Settings".

  5. Confirm that you will receive a notification on your smartphone.
  6. The alarm sound will stop if you tap 𝗠𝗶𝘀𝗱𝗲𝘁𝗲𝗰𝘁𝗶𝗼𝗻 or if time passes, as the notification is also displayed on the main screen.

Note 1: For quicker notification, the initial alarm won’t acquire location information after Lock mode is turned on.
Note 2: If the device detects movement for the second or subsequent time while locked, it will acquire location information and then send a notification. This may take up to 3 minutes, depending on the reception of GPS satellites, but usually takes about 60 seconds. If the Wi-Fi signal is active, the positioning will be completed in a short time.
Note 3: After the second data transmission has been completed, a one-minute waiting period is set. Note 4: By default, the alarm will not go off after the fourth time the device is locked and motion is detected. Because we believe that it is better to track the location of the device than to keep sounding the alarm in case the device is taken away. You can change this setting under 'Advanced'.


14. Advanced device settings

For more information on the detailed settings of the AlterLock device, please refer to this page.

To deactivate a device

Deactivation of the AlterLock device is done in the following cases

  • When you no longer intend to use the device
  • When using a different smartphone
  • If you are unable to reconnect or operate the device
  1. On the main screen, select the "Control" tab and tap 𝗗𝗲𝘃𝗶𝗰𝗲 𝗦𝗲𝘁𝘁𝗶𝗻𝗴𝘀.

  3. With iOS, open Settings > Bluetooth on the Home screen, select 𝗔𝗹𝘁𝗲𝗿𝗟𝗼𝗰𝗸 if it appears, and tap 𝗙𝗼𝗿𝗴𝗲𝘁 𝗧𝗵𝗶𝘀 𝗗𝗲𝘃𝗶𝗰𝗲.

15. Estimated battery life

The approximate operating time of the fully charged device in each state is as follows:

StateOperating time
No Periodic Transmission 45 days
Periodic Transmission (24 hours) 35-40 days
Periodic Transmission (3 hours) 16-28 days
Periodic Transmission (1 hour) 7-15 days

Note 1: The above figures show the operating time during Bluetooth connection. If the Bluetooth connection time is short, the operating time will be slightly longer than shown.

Note 2: The battery is designed to operate over a wide temperature range, but conditions below 0°C or above 45°C may reduce the battery life or cause damage.

Note 3: Locating the device or sounding the alarm consumes a lot of power. The time taken to locate the device depends on the environment, and therefore the operating time may vary significantly.

Tips to make your battery last longer

Do not store the device in extremely hot or cold environments.

Routine storage in direct sunlight or in a car during the summer months, prolonged storage in freezing conditions, or repeated charging may damage the battery and reduce its operating time.

Periodic transmissions should only be used when necessary.

We recommend that you only turn the device on when riding, as periodic transmissions of location data and data transmissions consume battery power.

Deactivate the device if it won't be used for a long time.

If you aren't going to use the device for a long time, charge the battery for about an hour and deactivate the device before storing it.
