There should only be two possible causes for an incorrect time to be displayed on Ubidium. 

No GPS Signal Found

In order to obtain a GPS lock for GPS time Ubidium requires a high level of GPS signal lock, this is often not possible to achieve when inside a building. If you are inside, please move to an outdoors location, in some open space, to re-sync the GPS. 

To attempt to sync to GPS time again, open the Time Settings by pressing the top Navigation Button. This opens a second menu with additional options, press the top Navigation Button again to open the Update time menu.

In this final menu, press the top Navigation Button one more time to Update time, this will force Ubidium to attempt to Sync to GPS if available or Sync via NTPD whichever is available. 

When Ubidium cannot locate a GPS signal, and no NTPD time is available, then it will use the time of its internal clock to set the time. This internal clock still maintains a high level of accuracy, even when the system is switched off, however it may therefore not reflect the correct time zone. In such cases the time will normally be incorrect by a value of hours only, see the following section to check the time zone. 

Incorrect Time Zone

It is usually possible to identify an incorrect time zone when the system time is incorrect by a factor of hours, but the minutes and seconds are correct. This may occur when the system cannot obtain GPS time and so reverts to the internal clock, or potentially if you are operating close to the border of two time zones. 

The time zone can be manually set through the Time Settings menu which can be opened by pressing the top Navigation Button. This opens a second menu with additional options, press the third Navigation Button again to open the Timezone menu.

Here you can choose to set the Timezone from a list, press the top Navigation Button to open the list of available Timezones. Recently used Timezones will be displayed at the top of the list, Timezones are then sorted alphabetically, first grouped by region and then by city. You can scroll the list faster by pressing and holding the corresponding Directional Button, then select the Timezone with the OK button. 

When being used as an Active system a Loop Cable is used to activate the Transponders which generate the times.

This loop cable must be secured to the ground, covering the full width of your timing point, it is important to ensure that the loop cable is setup correctly to ensure reliable and accurate recording of times. The Loop Cable is connected to the Active Loop Port on the back of the system , NOT the Trigger port under the flap. You additionally need to raise the black 2.4 Ghz antenna so this is pointing vertically up, this is used to receive data from the transponders. 

Loop Cable Setup

The loop cable should form a rectangle with a width of 60cm, the exact line on which you wish to record a time should be positioned across the middle of the length of the loop.

Normally the loop cable will be fixed to the ground using duct tape along the length of the loop, or covered with a mat to secure it in place. Loops can be buried in the ground, particularly for motorsports or on soft surfaces, when doing so it is common practice to protect the loop using some sort of pipe. 

Where possible use a loop of exactly the required length, never coil any excess loop cable since this can cause interference resulting in transponders not being activated. Loop cables cannot be installed on metal surfaces, this will completely inhibit the loop signal meaning no passings will be generated. 

Loop Settings

Depending on where transponders are being worn or mounted, and the setup of your loop, it may be necessary to check the system settings to adjust the detection height of the loop. This is done by adjusting the Loop Power setting. 

To open the settings for the Active Loop, press the Navigation Button second from the top, this opens a menu for Detection Settings, which now has 3 options, the top one is for Active, so press the top Navigation Button to open this menu. 

To change the Power value press the Navigation Button next to this menu item, you can now adjust the Power in increments of 10, from 0 to 100, by using the up and down Directional Buttons, then pressing the OK button to select a value.

A higher Loop Power will result in a higher maximum detection height, a value of zero will mean the Loop is switched off.

As a general rule you should try to ensure that the system can detect transponders at a height 50% higher than the expected maximum height of a transponder. To test the maximum detection height, walk away from the loop to a point further away than the maximum height, hold the transponder at the height you wish to test and walk across the loop at a moderate pace.

If the system generates a passing, which will be indicated by both a beep and red LED flash then the transponder was detected, if no passing was generated you may need to first move further away from the system or adjust the Loop Power. 

Normally it is only necessary to change the Channel and Loop ID values if you are working with multiple systems or Loop Boxes for additional timing points. The use of Channel and Loop ID is explained in the Active Settings guide.
