Troxler Enhanced RoadReader Plus 3451 Manual Of Operation And Instruction page 52

Once the PDA establishes communications with the gauge, the
software displays the status of the gauge's nickel-metal hydride
(NiMH) batteries, as shown in Figure 3–10. This display includes
the charger status (ON or OFF), the actual battery voltage, and the
battery status (OK or LOW). Press the 〈Done〉 button to continue.
If the battery voltage falls below 5.5 V, the gauge shuts
off. Recharge the NiMH batteries as described on page
C–24.
The gauge then enters a five-minute warmup period, which allows
the baseboard electronics to warm up, and the gauge to acquire GPS
data.
If the operator presses 〈Abort〉 to bypass the gauge
warmup, Troxler does not guarantee the accuracy of the
GPS location data.
To preserve battery life, the gauge shuts down
automatically after five hours of inactivity.
