* Battery power remaining display is omitted in this manual.
Note:
1) The battery operating time will vary depending on the environmental conditions, such as
ambient temperature, charging time, and the number of times charging and discharging the
battery.
2) In low temperature (especially while the heater of display is working), the battery operating
time will shorten to one-half of normal temperature use.
3) The indicator for battery power remaining shows the power level during each measurement
mode. The condition indicated for the battery power remaining in the angle measurement
mode may not be adequate to measure a distance. Changing from angle mode to distance
mode during a poor battery condition may cause the EDM not to measure a distance.
We recommend that you check the battery condition before going into the field.
4) Also note, when changing from one measurement mode to another, the battery indicator may
not show a decrease or an increase immediately. The battery indicator system was designed
to show the general condition for the battery strength. It does not respond instantly.
5) For more information on battery usage, refer to Chapter 13 “POWER SOURCE AND
CHARGING” .
