Changing Receiver Modes
The receiver has the following information and power modes:
• Normal Mode – the standard surveying mode.
• Extended Information Mode – used for testing purposes during
normal operation.
• Sleep Mode – used to stop recording data, but keeps the receiver
powered on “standby.”
• Zero Power Mode – used to prevent battery discharge.
Entering Extended Information Mode
Extended Information Mode (EIM) is used for receiver testing
purposes. In this mode, the receiver continues to work as usual, but
the STAT LED indicates “extended” information using a delimiter.
The Delimiter is a distinguishable double-blink that shows the overall
status of tests performed in EIM. The STAT LED color for delimiter
is calculated from the colors of other LED blinks, and becomes one of
the following colors when the tests complete:
• Orange – at least one blink is orange.
• Red – no orange blink and at least one red blink.
