3 Troubleshooting
Receiver won't turn on
The R1 GNSSreceiver will not turn on. There is no LED indication when the Power button is
pressed.
Cause: The battery is severely discharged. This may be because the device is new and has
not yet been charged, or it has been in storage for more than a few months.
Solution:
Charge the battery for an hour using the supplied charger, then disconnect and
reconnect the USB cable. The Power LED should turn on. Leave the device on
charge until the Power LED = (Green).
See Charging the battery, page 12.
Battery indicator for R1 GNSSreceiver shows empty
on an iOS device
On an iOS device, the small battery level indicator at the top of the status bar shows empty
in error.
Cause: This is an iOS issue which has been logged with Apple.
Solution:
Use the GNSS Status utility to view the battery status. See Using the GNSSStatus
utility, page 16.
R1 GNSSreceiver firmware upgrade
When you upgrade the firmware on a R1 GNSSreceiver, and it was previously paired with
an iOS device, you cannot reconnect.
Cause: The iOSdevice no longer recognises the R1 GNSSreceiver when the firmware is
upgraded on the receiver.
Solution:
Before you can reconnect your iOSdevice with a previously connected R1
GNSSreceiver, you must 'forget' the connection on the iOS device:
1.
Go to Settings / Bluetooth, and tap the Info button next to the R1 [serial
number] device you want to forget.
2. Tap Forget this device.
