6 Connecting and Personalizing
We strongly recommended that you personalize your SavvyLevel device. This ensures that you will
quickly be able to identify your device. The Passkey feature will prevent any unauthorized users from
accessing your device.
1. Make sure your SavvyLevel device is powered on.
2. Select Connect device in the main menu and from the list of
scanned devices, select your device to make a connection.
The factory default device name is SavvyLevel. See Figure
1.
3. When presented with a Passkey Logon screen, enter your
device passkey. The factory default passkey is 000000. See
Figure 2. Once logon is successful, your Smartphone will remember your passkey when re-
launching the app. Make sure you record your passkey.
If you use more than one Smartphone to connect to your SavvyLevel then it must also use the
same passkey.
Once connected, you can begin to personalize your device.
Changing your passkey
A passkey is used to encrypt data between your Smartphone and the SavvyLevel device. If you
change your passkey then make sure you record your changes and place it in a safe location. If you
forget your passkey you must reset the SavvyLevel device. See section 9 Reset SavvyLevel to
Factory Default.
1. Select Security in the main menu and then select Change Passkey. You will see the
Passkey Change screen. See Figure 3.
2. Enter a new passkey. You must enter exactly 6 numbers or characters (alphanumeric).
Characters maybe upper or lower case. Special characters are not accepted.

Changing your device name
You can further customize your SavvyLevel device by changing its Bluetooth broadcast name. This
can help you identify it when you have many listed Bluetooth devices.
1. Select Security in the main menu and then select Change Device Name. You will see the
Device Name screen. See Figure 4.
2. Enter a new name. You may enter up to 11 numbers or characters (alphanumeric).
Characters maybe upper or lower case. Special characters are not accepted but with
exception to the space and underscore characters.
7 Zero Level Calibration
Zero level calibration only needs to be performed once after the
SavvyLevel device is first installed. It uses sophisticated thermally
compensated algorithms to achieve unprecedented precision over a
wide range of operating temperatures.
For best results calibration should be performed at median
temperatures around 25°C (77°F), with the SavvyLevel device
temperature stabilized.
To calibrate:
1. Place your caravan/RV/4WD or trailer on level ground or at
its preferred level for comfortable use.
2. Make sure your SavvyLevel device is powered.
Select Settings in the main menu and then select Zero Scale. Press
OK to complete the action. See Figure 5 and 6.

10 Troubleshooting
Q –I get very poor Bluetooth signal range.
A –The most likely cause is that there are too many signal obstructions (metallic objects) in a direct
path, between your Smartphone and your SavvyLevel device.
Try to operate your Smartphone in a different location. Try opening hatches or window coverings in
your caravan where your SavvyLevel is installed. Try to place your SavvyLevel in a better location.
Refer to the ‘Installation Guide’ sheet.
Q –My compass does not work.
A –Check that your SavvyLevel is not too close to magnetic or ferrous objects. Refer to the
‘Installation Guide’ sheet.
