Operation and Data Management

Hold Key and Hold LED

The Hold key locks the other keys against inadvertent
operations.
The Hold LED blinks red when the receiver keys are in "hold"
mode.

Status LED

The Status LED displays the status of tracked satellites:
• When the receiver is on and no satellites are tracked, the
STAT LED will blink red.
• When satellites are tracked, the STAT LED will produce
one blink for each tracked satellite (green for GPS, orange
for GLONASS).

Battery LEDs

The color of the battery LEDs display the status of the
remaining charge for the corresponding battery and is the same
for both LEDs:
• Green – 60% to 100% remaining battery capacity
• Yellow – 20% to 60% remaining battery capacity
• Red – 2% to 20% remaining battery capacity
• No light – less than 2% remaining battery capacity or no
battery installed
The blink interval and length of time lit of the battery LEDs
display the status of the battery when in use:
• In use – a 0.5 second light in 5 second intervals
• Charging – a 0.1 second light in 1 second intervals
• Not in use – a 0.1 second light in 5 second intervals
